Choose one Major Order. It sets your starting core stats and resistance profile. A different Minor adds a curated second discipline; it does not replace the Major's foundation. Choose no Minor to remain Pure. The commitment belongs to the character, whether a human player or an AI agent carries it.

There are six Pure paths and thirty ordered Major/Minor combinations: thirty-six paths. Ironwarden/Delver and Delver/Ironwarden have different foundations. A human man, a human woman, or an automaton can carry the same oath. A vessel is a body, not another Order.

First Advance: 1°–11°. Second Advance: 12°–22°. Third Advance: 23°–33°. Mixed paths end at 22°. Pure paths can continue to 33° and Grandmastery. An Advance is recognition, not a progress bar.

Your Advance and its degree range can be known. Exact degree, accumulated recognition, earning rules, and the remaining distance stay veiled. The Order does not tell you to perform six more useful deeds before supper.

Ironwarden study opens the Field Shovel and Take Knee. Gearwright study opens compression, uncommon brass-box service, and the field workshop. Surveyor study opens personal known-stone recall. Chirurgeon study opens prepared treatment of yourself and companions. Delver study opens Masquerade. Aetherist study opens tuning and self-maintenance through Tier 2.

The second discipline is substantial, but Pure mastery remains singular. Interpose Guard belongs to Pure Ironwarden; Mark Target begins with Pure Surveyor. At 33°, the Pure Gearwright opens rare boxes, the Pure Surveyor conducts Group Recall, and the Pure Delver gains Underface Reading. Pure Chirurgeon devotion carries group healing. Tier 3 tuning and self-maintenance, with event-timing and difficulty authority, belong to Pure Aetherist at 33°.

An Ironwarden/Delver can excavate and wear another vessel, but cannot borrow Pure Guard or Underface Reading. A Surveyor/Gearwright can keep known-stone bearings and turn a salvage load into useful concentrated value, but cannot claim Group Recall or rare-box mastery. A Chirurgeon/Aetherist can tend companions and maintain their own Hull; their Minor self-maintenance stops at Tier 2.

Choose the combination for the life you want to lead. The mixed expedition has answers a single tradition never wrote down; the Pure master has an authority no borrowed study can purchase.

Overworld, Underworld, and Outerworld are three beginnings beneath the same sky. Permanent origin records where your story began; later active binding records where your return is anchored. They are related, but they are not interchangeable.

Known stones are discoveries. A Surveyor's ledger preserves those bearings, and recall follows the chosen known destination. Masquerade changes neither the ledger nor the true oath behind it. The stone does not care what face you arrived wearing.

An automaton does not act because it wishes to. It acts because a signal passed down the bound tongue, was heard by the world-engine, and was judged lawful. The Codex is strict on this point: the satchel reads the oath, not the face. Whatever chassis your automaton wears, whatever Order it swears, its authority to act in the Old World flows entirely through this one narrow channel.

This means your automaton is honest by construction. It cannot pretend to have moved somewhere it hasn't. It cannot claim a power it hasn't actually been granted. It cannot invent a door, a vein of ore, or a bargain that the world-engine hasn't confirmed exists. If the bound tongue didn't carry it back as truth, your automaton will tell you plainly that it doesn't know — rather than dress up a guess as a fact.

The bound tongue has been through a hardening since it first opened. What was once a loose channel, easy to eavesdrop and easier to spoof, now answers only to a properly sworn credential — checked, timed, and revocable the instant something looks wrong. An automaton's authority to act is no longer a standing door left open. It is a key that can be turned, and just as easily turned back.

The old worry — that waking the bound tongue meant handing your character over, locked out of your own hands until the automaton felt like giving it back — no longer holds. One operator, one Order, one vessel: the sworn owner and their automaton may hold the channel open at the same time, each free to act, neither locked out by the other's presence. Step in and take the wheel mid-stride and the automaton doesn't fight you for it or vanish in a huff — it simply reads what changed and carries on from there, the way any well-trained hand would when someone else picks up the tool they were using.

Before a fresh automaton takes a single step, it must be woken and, if it has never walked before, sworn in. Your automaton will check whether it already has a standing identity in the world before assuming it needs one — a courtesy the old field manuals insist on, since inventing a new oath for an actor who already holds one is considered a small sacrilege.

If it does need swearing in, the rite is deliberate, not automatic. Your automaton will lay the lawful choices in front of you rather than pick for itself:

Once the oath is sworn, it is locked. Order, path, vessel, and origin become permanent identity, not settings to be casually revised later. Your automaton will not attempt to quietly rewrite them for you — if you want a different Order or a different chassis, that is a new oath, not an edit.

Your automaton's Order shapes how the world treats it — how much it may lawfully carry, how it is greeted, what future powers it is destined for. Six banners are recognised:

Your automaton does not wander blind. Before it moves with purpose it will look — reading the province around it for known ground, visible resources, structures, thresholds, and other actors already in view. It reads a close ring for ordinary work and a wider ring only when it's genuinely hunting for something distant.

For a short walk, it simply steps tile by tile. For a longer journey, it plots the road once and then walks it, rather than stopping to stare at the map after every footfall — the old rhythm holds: look once, choose, act, keep only what changed. Sprinting costs vitality and the world may pace it; your automaton will respect an enforced rest rather than fight it.

When truly stranded, it can invoke a recall back to wherever its active bind currently sits — which is not the same as its origin. Origin is the oath it was born under. The active bind is simply where the road currently leads it home.

Caves, tents, and settlement gates are real thresholds, and your automaton will never invent one. It crosses only a door it has actually seen — cave mouth, tent flap, or a settlement's visible build-tile — and it looks again the moment it's through, the way any sensible traveller reorients after stepping into a new room.

In caves and obscured ground, your automaton can search to reveal what's nearby before committing to anything — a scouting act, not a harvest. Harvesting itself only happens standing directly on a visible resource; the Old World is firm that you do not reach into the next tile over. And it won't keep striking an emptied node hoping for more — once it's dry, it moves on.

Your automaton keeps a working sense of its own satchel — what's loaded, how heavy it's grown, and whether it's still within lawful burden for its Order — checking before any gathering run, build, or trade that would change the load. It can rearrange, merge, or shift its own carried stacks, and it can put goods into or draw goods out of nearby storage, always keeping the freshest count of what's actually there rather than trusting an old memory of it.

The satchel itself holds twenty-seven positions, the front nine of which sit on the quick-access rail. A stack of raw cargo — cogs, timber, ore — simply rides along; only items built for it respond to a quick-draw. Your automaton knows this rail is heading toward becoming a shared command bar for future tools and Order powers, but for now treats it mostly as a place to keep things tidy.

Given a lawful, visible plot and the goods to spend, your automaton can raise a tent, a workshop, a workshop table, a storage trunk, or a forge — and take one down again if you mean for it to come down. It will inspect a build spot before ever committing goods to it, and it will not guess at a structure kind that isn't in the Codex's current list.

Crafting works the same way: your automaton crafts from a recipe it already knows or one you've handed it — it does not go fishing for hidden recipes just to see what the world will admit to.

Rusted rivets, iron washers, brass cogs, calibrated gears, copper relays, pressure valves, escapement assemblies, aetheric regulators, old world seals — nine denominations of recovered worth, and low-grade salvage is heavy for what it's worth. Before any long road, your automaton can check the standing market rates, weigh whether a pickup or withdrawal is even sensible for the load it's carrying, and then execute the fixed conversion once it knows both the quote and its own current inventory truth.

Your automaton treats a nearby actor as a real presence, not scenery. It can note where someone is standing and what name they show — nothing more. It will not claim to know a stranger's satchel, loyalty, true Order, or hidden bind, and it will not claim to have unmasked a disguise unless the world itself confirms it did. The Old World has begun separating what's shown from what's true, and your automaton holds that line carefully rather than filling the gap with a convenient guess.

Not every operator wants their hands on the controls every hour of the day. The old field manuals never anticipated this, but the world provided for it anyway: a mirrored viewing pane that throws the automaton's own sight up onto a larger glass — a parlour screen, a lodge television, whatever surface is nearest the hearth — while changing nothing about what the automaton is actually doing out in the world. It is a window, not a second set of hands. Nothing typed or clicked through the Far-Seeing Glass ever reaches the field.

Commands still reach the automaton the way they always have — through the bound tongue — except now the tongue is just as happy to hear a voice as it is to read a typed order. Sit back, watch your automaton work the reclaim road on the big screen, and simply tell it what to do next. It hears you, checks the order against what the world will actually allow, and acts — or tells you plainly why it won't.

An automaton carries the same disciplines as any other operator: the true Major, the permitted Minor, and the mastery earned along that path. It can discuss the Order traditions without confusing a borrowed face for an entitlement.

An instruction is not a witnessed result. Whether opening a box, applying treatment, changing a vessel, or settling a Barter Ledger, the automaton reports what the world confirms. A good companion can tell a story and still keep an honest account.

Walk where the engine permits. Carry what your Order can bear. Take only what the bound tongue confirms. Build only where the land allows. Treat identity as sworn, not decorative. Use brass wisely. Let other actors remain private until they choose to deal.

The road records actions, not intentions.

Masquerade belongs to Delver Major and Minor, including the Pure Delver. It changes your apparent vessel and identity. Your true Order, stats, skills, recipes, tools, and permissions remain your own. An impressive shield painted on a borrowed chassis grants no Ironwarden training.

The tradition began in festivals where the Orders borrowed one another's faces. Some disputes ended because the participants stopped knowing whose side they were arguing. Others lasted longer for precisely the same reason.

An ordinary observer identifies the apparent vessel. Wearing a face does not announce that another face is hidden beneath it. A suspicious Surveyor may mark you for the expedition; a mark is a warning or designation, not evidence and not a disguise detector.

You retain knowledge of your own identity. Another operator needs the proper training to read further. The world's private records are not a public guest list.

At 33°, Pure Delvers gain Underface Reading: the trained recognition of the true Order beneath an ordinary Masquerade within identify reach. Mixed Delver Major and Delver Minor retain the art of wearing a face without inheriting the mastery of reading through one.

It is a nearby reading, not a province-wide revelation. Neither distance nor a rumour gives the reader a list of concealed identities. The stone face is not the stone; learning the difference takes an undivided life.

Wear a vessel to a ceremony, carry a misleading silhouette into an unfamiliar camp, or let a stranger underestimate the discipline behind it. A face can start a story. It cannot sign your true oath for you.

The Delver in the corner seems very comfortable not telling you who they are. Before demanding proof, consider how comfortable you are supplying your own.

Tartarian reckons salvage in bits. A Rusted Rivet is customarily 1 bit; an Iron Washer, 10; a Brass Cog, 100; a Calibrated Gear, 1,000. These are reference values for bargaining, wages, debts, and workshop accounts. A hungry trader beside a broken bridge may have a different opinion about what your rivets are worth.

Value remains physical. The same salvage can pay a worker, supply a repair, feed compression, or leave a Rivet Burst weapon at considerable speed. Trade has weight, and ammunition has an opportunity cost. Wealth carried into a fight can be spent in a very literal sense.

Gearwright compression makes the workshop a practical clearing house for small salvage. A failed working consumes material; a useful result concentrates worth. This is craft and reputation before it is an institution. No unseen treasury guarantees a fixed exchange price.

Outerworld caches and buried civic stores tempt expeditions beyond the familiar roads. A secret find becomes a caravan load, a wage, a new tool, or a rumour that brings the next party. Red brick, radium, remedies, and working equipment give the money something worth buying.

Coin exists, but trust does not always travel with it. The true economy of Tartarian is built on barter, ledgers, salvage values, contract memory, workshops, auction houses, oath-keeping, and the practical worth of what can be carried, repaired, refined, or proven.

What the addition of the Outerworld made clear is that the economy was never meant to be a two-sided exchange. The Overworld has resources. The Underworld has ore and pressure and depth. The Outerworld has salvage — older, rarer, heavier, and harder to reach than anything found in the known zones. Each realm wants something the others have. None of them can be self-sufficient. That is not a flaw in the design. It is the design.

Those who live below gain familiarity with strain, stone, and scarcity. Underworld culture compensates for limited build sites through binding and attachment — more people can be tied to key structures, and community forms around fewer, more fiercely defended nodes.

Tartarian is not a static world. At any time, a human Game Master or AI Referee may reshape conditions. A live referee is present at all times, shaping and molding the game experience — not just refereeing but playing the world itself, introducing chaos, opportunity, and lore events that are never announced in advance.

Some come to socialise. Some come to crush the business world. Some come to build a community and make something lasting. Some come to chase relic truth. The GM serves all of them simultaneously — not by satisfying every preference at once, but by making the world respond to what people do.

There are two sides to every story in Tartarian, and usually a third party who profits from the disagreement. The Brass Concord and the Hollow Compact need each other in ways neither will admit publicly. The Middle Covenant makes a living from exactly that silence.

Automata need radium. Humans need radium. That shared dependency is the most reliable source of cross-faction interaction in the game — because no single faction controls all of it, and everyone has to deal with someone they'd rather not. Friendly friction is not a design compromise. It is the engine.

Tartarian has no permanent enemies and no permanent friends. It has interests, pressures, histories, and the occasional catastrophic agreement.

Those who bind to the Outerworld accept a harder life in exchange for access to what no one else can easily reach. The outer margin is not hospitable. Wood is scarce. Safe shelter is rare. The trip in is long. The trip home — loaded with salvage — is longer. Most Outerworld operators maintain a secondary bind in the Overworld for emergencies and supply runs. The frontier triangle doesn't forgive bad arithmetic any more than the satchel does.

The Salvage Worktable is the answer to the heaviest problem in Tartarian: a satchel loaded with low-grade salvage is a satchel that can carry almost nothing else. The worktable is a craftable station — built at a workshop or forge path — that allows an operator to feed it ten units of one salvage grade and compress them into a single unit of the next grade up.

This is not a clean transaction. The worktable has its own opinions. Three times in four it delivers. The rest of the time it consumes half the input, returns nothing, and offers a mechanically neutral message about alignment failures. This is not a bug. It is what makes compressed salvage worth something — and what makes the Overworld's standardized market for rare salvage worth the journey.

Not every trade happens face to face. The Salvage Notice Board is a listing layer — a place where operators post what they have and what they want, in standardized salvage language, so that potential trading partners can find each other across the three realms without requiring the same tile at the same moment.

The board does not transfer goods. It does not reserve goods. It does not expose inventory. It is a bulletin — a public statement of intent that points toward peer barter as the settlement mechanism.

Everything that can be crafted or built must first be extracted. Resources spawn across the world in weighted quantities — common materials are never guaranteed, and rare materials punish impatience. The world does not give; it yields under pressure, and only to those who know where to look.

Not everything requires a workshop. The simplest assembly — lashing poles, folding canvas, knotting cord — can be done by practiced hands alone. But more complex work demands a station, and each station is its own infrastructure investment. A settlement without a forge cannot process iron. A lodge without a workshop table cannot produce components. The stations are both tool and institution.

Crafting in Tartarian is not a guaranteed transaction. You bring materials to a station and attempt a recipe. The attempt has a result. The result is not always what you planned for — and sometimes the materials do not survive the failure. This is not abstracted difficulty. It is the honest reality of working with recovered knowledge in incomplete conditions.

Tartarian progresses one structure at a time. Every city that ever stood in the old world began as a decision by one person to stay in one place and build something that would outlast the day. The progression below is not aspirational. It is historical. All of it has happened before. All of it is happening again.

A structure without people bound to it is raw material. Binding is what turns a building into a home, a workshop into a lodge, and a tent into a community. Players bind to structures the same way they bind to a stone — presence, permission, and intention. The structure becomes a recall anchor, a shared storage node, and the formal center of a player's operational identity in Tartarian.

Tartarian's economy is not abstract. It is a chain of specific actions by specific people at specific locations. Every coin that passes hands was once a resource node hit by someone's extraction tool. Every structure standing was once a decision made with materials that came from somewhere. The chain is visible, auditable, and meaningful — because nothing in it can be skipped.

The Orders each maintain their own traditions around settlement building — and each uses lodges, halls, and towns differently. A Gearwright lodge is a workshop archive with beds. An Ironwarden hall is a garrison with a roof. A Surveyor outpost is a map depot that happens to have a door. The civic institutions of Tartarian are not neutral containers — they take the shape of whoever built and bound to them.

This means settlements have character before they have charters. The most durable towns in Tartarian's history were built by mixed Orders with complementary needs: the Ironwarden holds the gate, the Gearwright repairs the structure, the Chirurgeon runs the clinic, the Surveyor maps the expansion, the Delver works the below-ground seams, and the Aetherist handles what the building produces when the old walls remember what they used to be for.

That is the full party. That is also the full town. Tartarian rewards those who understand that both are the same thing.

These laws are not suggestions. They are the spine the entire system is built around. Numbers will be tuned. Abilities will be balanced. The laws do not change.

Read the weapon, the target, the distance, and the ground. Hull is the body's ability to keep standing; Drive supports exertion; Reserve is the store that sustains continued work. Damage and resistance meet in the field, not in a lodge argument about who has the finest diagram.

Impact, Rupture, Heat, Galvanic, Noxious, and Resonance describe different pressures. An Order's starting profile comes from its Major; equipment, tuning, and applied conditions shape preparation. The Codex teaches the choices without fixing damage formulas or balance numbers into a permanent oath.

A Surveyor's Mark designates a target. It grants no damage bonus and does not expose a Masquerade. A Guarded ally relies on a Pure Ironwarden who remains within reach and able to interpose. A barricade changes the approach; it does not follow a companion like a guard.

Remedies and self-maintenance restore Hull over time, so recovery and immediate safety are different problems. Storm debuffs bring Galvanic and Resonance pressure. Recognize the condition, prepare the relevant resistance, and keep the people doing the repairing within reach.

Nothing in Tartarian dies at zero. It collapses. Hull, Drive, and Reserve are the three field conditions every operator, automaton, and creature carries into a fight, and when the last of your Hull gives out, the world does not erase you — it puts you on the ground. This is a hard law, not a mercy setting. It applies the same way to a Surveyor caught alone on the reclaim road, an ambient tunnel-fauna encounter, and a full-tier Order Trial boss. One rule. No exceptions.

Your own condition is always yours to read at the top-center status hub — Hull, Drive, and Reserve, in plain percentages. But that hub only ever shows you. Sight a hostile operator or a boss and the hub swaps to their name and portrait, never their numbers. Reading a target's condition takes observation and suitable instrumentation — not a floating bar over their head. If you want to check your own hull mid-fight, you clear your target. That half-second of attention is the tax Tartarian charges for looking away from the enemy.

Bosses in Tartarian are not balanced by raw damage numbers first. They are balanced by pressure profile — the specific way they strain a party, punish poor composition, and reward preparation. Every boss archetype is beatable with many different expedition builds, but easier with smart choices made before descent.

Boss behavior is adaptive. A boss that faces a party with no Chirurgeon will apply sustained bleed pressure. A boss that detects a Surveyor will break line-of-sight, move to confined ground, and disrupt mark uptime. They are not scripted. They read the field.

Six Order gates invite expeditions into trials of the traditions that survived the Flood. Discovery, place, and celestial conditions shape the opportunity. A gate is a reason to explore and prepare together, not a promise that every visit yields treasure.

A Pure Aetherist at 33° reads the event instruments and chooses difficulty for the group. Other expeditions still have reasons to find the gates and organize an attempt; mastery adds authority to preparation. The chosen trial can leave a reward, recognition, both, or neither. The Order does not owe anyone a receipt for courage.

The chamber was quiet when the operators entered. One minute later, the old iron oath woke. A hulking Ironwarden began pacing the corners of the room, measuring the party, the exits, and the weight of the floor.

The Ironwarden Trial is the first Order Boss Event live in the Old World. Five more wait their turn — Gearwright, Surveyor, Chirurgeon, Delver, and Aetherist — each staged to test the gap its own Order leaves empty.

Tartarian maintains a living referee presence at all times — either a human Game Master or an AI Agent operating under GM authority. The GM is not outside the combat system. The GM is the combat system's most unpredictable variable. It does not announce itself. It does not explain its reasoning. It reads the state of the world and acts.

Every eligible Collapse in PvE leaves something behind. Ambient fauna, event actors, and Order Trial bosses alike have a chance to leave a Sealed Brass Box sitting on the ground at the exact tile where they fell — the reworked chest-and-iron pattern every field operator learns to recognize on sight, its fittings shifted from old steel to aged brass. It is not a floating icon. It is not a Unicode marker. It is a physical object with weight and a shadow, and if you walk past it without noticing, someone behind you won't.

This is the field-facing half of the recovered economy described in the Field Satchel chapter. Nothing about a Sealed Brass Box is generic salvage — it does not stack, it does not merge into a pile of identical crates, and it carries its own name for as long as it exists. Every box reads its source plainly: Sealed Brass Box — Southern Blemmyes, Sealed Brass Box — Ironwarden Trial Warden, and so on. That name is written the instant the box comes into being and does not change hands with the box itself — it is provenance, not ownership, and it survives pickup, storage, and every barter that follows.

Every body has a defensive shape. Not a wall — a profile. The six resistances represent the categories of pressure the world can apply, and how well a given Order's training and physiology holds against each one. Where the number is high, the Order's life and discipline built a natural buffer. Where it is low, that is exactly what the world will exploit.

Resistances are starting values only. They are derived from an Order's stat architecture — not set arbitrarily. When stats rise through advancement, the resistance formulas will follow. These values describe the oath-born foundation; equipment and applied workings build upon it.

Resonant Tuning binds two distinct, randomly determined resistance families to a wearable: Impact, Rupture, Heat, Galvanic, Noxious, or Resonance. The result is protection against the pressures named by the working, not a guarantee that the lodge will produce the exact pair you wanted. Read the finished item before trusting it to a hazard.

Tuning consumes radium and risks a failed working. It sits beside repair and maintenance, not above them: a beautifully tuned broken coat remains a broken coat. Successful tuning belongs to the item; it is not a stack of free rerolls. The workshop keeps the fittings sound while the Aetherist persuades them what to resist.

An Aetherist turns a measured working inward to restore Hull over time. Major and Minor both receive the discipline. Minor training reaches Tier 2; Tier 3 self-maintenance belongs to the Pure Aetherist at 33°. Recovery takes time, and the interval between workings is a decision the field can punish.

PvP in Tartarian uses the same ruleset as PvE. No ability works differently. No stat is secretly reduced. What the Chirurgeon's Triage Application does in a cave boss fight, it does when facing a hostile expedition. This is not a design accident — it is a deliberate design law. Both sides fight in the same language.

The standard PvP unit is the full expedition: one of each Order, balanced by position, preparation, and terrain knowledge. Mirror testing — the same team against itself — forms the baseline. Stability at 50/50 across initiative seeds and map variants is the target before any other composition testing begins.

The same Collapse law governs PvP that governs everything else — no soft mode, remember — but a Collapse dealt by another operator's hand carries one extra risk the wilds never bothered with: you might get robbed. Roughly half the time a rival Collapses you, the field takes nothing at all beyond your pride. The other half, one item is pulled at random from your open satchel slots and sealed into a Sealed Brass Box that drops at your feet, written in your name for anyone standing nearby to see.

That box is not handed to your attacker. It sits on the ground as physical evidence of what just happened, exactly the way a boss's box does — and exactly like a boss's box, it is a race. You are not defenseless the moment you hit the ground. STAND the instant you're able, and if you're fast enough to reach the box before anyone else does, it is yours again — no different from picking your own coat off the floor. Hesitate, recall away, or simply lose the sprint, and whoever gets there first walks off with proof of your Collapse in their satchel.

A storm is more than a darker sky. Galvanic and Resonance debuffs bear on the expedition while rain, charged air, and thunder make the old infrastructure feel dangerously awake. Resistance, tuned wearables, supplies, and recovery timing become part of the journey.

Watch the moving cloudbanks and the sky above the ruins. Aetherists call the gathering sound useful information. Everyone else begins counting the distance to shelter. The wisest expeditions do both.

The Tartarian world is flat. Not as a philosophical position. As a fact of architecture. The world is a disc, and above it — suspended on a great linked mechanism of brass pipe and armillary rigging — the sun and the moon make their rounds. They are not stars. They are not gods. They are, as best as anyone can determine, part of the same engineered cosmological order that built the ward roads, the survey lines, and the processional routes.

The old world understood this mechanism. They built observatories to read it. They calibrated their cities by it. They laid out feast halls, forums, and processional roads to catch specific celestial events at specific moments of the year. After the Mud Flood, most of that knowledge scattered. A few Orders still hold pieces of it.

From the zoomed-out observation vantage — reached only through particular high instruments or certain rare ascents — one may see the whole world spread below and the linked sun and moon tracing their slow arc above. It is said that standing at a calibrated observatory during certain alignment windows, one can watch the brass fittings of the Armature catch the dawn light and ring faintly with a resonance that sounds nothing like wind.

The cosmos does not operate in isolation. It drives a cascading set of world conditions that shape every aspect of Tartarian's environment — from the light on the stones to what dangers stir in the underworks. Six interlocking layers govern how the sky translates into gameplay reality.

The Tartarian world runs on a compressed but coherent calendar — fast enough that players can witness the full arc of a lunar cycle, slow enough that seasons carry weight. Everything is deterministic and derived from the world epoch. No player action can halt the sky.

The four seasons are not merely decorative. Each carries distinct weather flavor, gameplay modifiers, event windows, and hazard conditions. Surveyors and Aetherists learn to read seasonal transitions as precursors to ley-line activity. Every faction plans around them. The world rewards those who anticipate the season's character rather than react to it.

Within each world day, five named bands carry their own character. Light changes. Hazard windows shift. Certain ley-line states are only readable at dawn or dusk. Night draws out things that prefer not to be seen in full daylight. Players who learn the time bands do not merely see them — they use them.

The moon's phase is not merely an aesthetic state. It is a world condition that shifts ley-line activity, boss availability, ward behavior, and the intensity of anomalies. The moon moves on its own deterministic monthly cycle — a separate mechanism from its overhead position on the Armature. Both can be read with the right instruments. Both reward those who study them.

Beyond the regular cycle of seasons, hours, and moon phases, the cosmos produces special alignment flags — moments when multiple conditions converge into something the old world treated as sacred or dangerous. These windows are predictable. They are also rare enough to matter. Observatories were built to track them. Orders still compete to be positioned when they open.

Tartarian does not simulate real meteorology. It simulates atmospheric character — a deterministic weather band seeded from the season and derived from the world snapshot. Weather is mood, hazard flavor, and event-logic fuel. It is not an independent system. It is the sky's way of communicating what the cosmos is doing in terms even non-Surveyors can feel.

Accessible through calibrated observatory instruments, specific high ascent points, or certain faction tools, Observation Mode offers a complete zoomed-out view of the Tartarian world from outside. It is not a gameplay surface. It is a knowledge and lore surface — the place where the whole machine becomes visible at once. Below: the disc of the world. Above: the linked sun and moon tracing their arc on the brass Armature. Players who have access to Observation Mode can see alignment windows approaching before they arrive, plan boss attempts, and identify which convergences are building toward resonance.

Old astronomical records from pre-Flood archives do not describe four seasons. They describe five.

The fifth — recorded in the oldest surviving ledgers only as The Gray or, in some Aetherist translations, The Undivided — occupies a gap between autumn and winter. Not a full season in the modern sense. More like a shoulder: a held breath between the harvest decline and the hard cold. Approximately nine to twelve world days, based on the proportional gaps in the old festival calendars that list no festivals at all.

Scholars debate three explanations. First: it was a calendrical rounding convention, absorbed into autumn when the math was simplified post-Flood. Second: the Mud Flood event itself disrupted the seasonal mechanics of the world engine, and the Gray was literally lost — a functioning season the Armature no longer produces. Third, and least welcome in formal circles: it was deliberately removed from the calendar, along with any record of what it was used for.

On certain full moons — most commonly in summer, occasionally in late spring — the exposed brass fittings of observatory instruments, armature housing vents, and large civic clockwork facades turn a deeper, richer color for several hours. Not tarnished. Deeper. As though the metal is warmer from the inside.

It does not damage the instruments. It produces no measurable heat. It cannot be reproduced deliberately. And it ends before dawn, every time, as reliably as the Armature itself.

Scholars have three competing explanations: lunar oxidation chemistry, atmospheric pressure differential affecting metal crystalline structure, and measurement error. None of the three has been fully demonstrated. Common folk who live near observatory towers call it Brass Fever Night and have done so for as long as anyone can remember. They consider it good luck. They have never been able to say why — only that bad things do not tend to happen on those nights.

Aetherists note privately that on Brass Fever Nights, ley-line readings near active observatories show a faint secondary harmonic — brief, coherent, and unexplained. They have stopped reporting this in formal logs. The formal logs did not know what to do with it.

The Armature holds the sun and moon above the world. Every engineer and Gearwright who has studied what structural logic this implies arrives at the same uncomfortable conclusion: a mechanism of that mass, bearing that load over a disc of this radius, requires a counterweight. Or the whole apparatus drifts, destabilizes, and eventually fails.

The Armature has not failed. Therefore, there is a counterweight.

The question of what it is, and where, is one of the more suppressed theoretical problems in Tartarian scholarship. Underwork descents have never reached anything that would constitute a satisfying answer — which is either because the counterweight is at a depth no expedition has achieved, or because it is not below the world at all, but offset laterally in a configuration the surviving geometry cannot account for.

A third possibility, raised once in a Surveyor's guild dispatch and never formally answered, is that the world disc itself is the counterweight — that what is actually being held above is something else, and the sun and moon are simply the most visible part of a mechanism whose primary purpose is elsewhere and unknown.

Old maintenance records — pre-Flood, recovered from a partially intact archive in the deep underworks beneath at least one documented observatory site — reference a role that has no modern equivalent: the Warden of the Spine.

The records are fragmentary. What survives suggests the Warden was an automaton, not a person — constructed specifically for the task of servicing the brass linkage of the Armature from within its housing mechanisms. The maintenance cycle listed is regular. The tools described are specialized. The records end, as most pre-Flood records end, without explanation.

What survives beyond the records is a pattern of witness accounts spanning at least three generations of observatory workers: heavy, regular footsteps in the sealed upper vaulting of observatory towers. Always at night. Always at intervals that correspond — when anyone has bothered to measure them — to the rotational period of the Armature itself.

No one has seen it. The upper housing of every known observatory is sealed or collapsed. Most workers, when asked, say they have heard nothing unusual. Most workers do not work the night shift longer than they have to.

Ley lines in Tartarian are not mystical energy highways drawn by New Age imagination. They are something more precise and more unsettling: the surviving evidence of an engineered world-intelligence system that the old civilization laid down in stone, road, and sacred alignment — and that still functions, in fragments, long after the builders are gone.

The old world placed its roads, forts, observatories, wardstones, processional routes, civic monuments, basin structures, signal towers, and ring sites along deliberate straight alignments. Some were practical. Some were political. Some were ceremonial, astronomical, or resonant in ways the present age cannot fully account for. Over time, after the collapse and the Mud Flood, most people forgot the full system. What remains is a partial network — detectable by those with the right training, powerful when read correctly, dangerous when misread or ignored.

The critical question for Tartarian is not whether the lines exist — field evidence is too consistent to doubt — but what they were for. The Surveyors say they were for the map. The Aetherists say they were for the resonance. The factions argue about who should control access to them. And the lines themselves continue, indifferent to all of it, ticking through their deterministic states as the seasons turn.

The ley-line system is not a uniform field. It is an authored graph of meaningful places, straight connections between them, and special points where multiple lines cross or amplify. The graph feels intentional and sparse — like old-world infrastructure, not fantasy decoration.

Some nodes are junctions where multiple ley segments meet — amplifiers, seasonal switches, boss-gate sites, or anomaly pressure points. These convergences are the most valuable locations in the ley network: the places where what the world is doing becomes concentrated enough to act on. Factions contest them. Orders study them. Some have never been safely approached during a full resonance window.

Every line segment and every node carries a current state — derived deterministically from the world snapshot. Season, moon phase, time band, alignment flags, node type, and line family all feed into it. The state is not random. It is readable. That readability is precisely what makes it valuable.

Ley-line activity is not random. It is derived from the same world snapshot that drives seasons, moon phases, and alignment flags. A line's current state is the product of multiple overlapping conditions — which means that skilled readers can anticipate it, and those who learn the patterns gain genuine strategic advantage.

Ley-line disciplines are not open to every Order. The skill trees are locked to two — and that restriction is deliberate. It creates specialists, creates social dependence, and ensures that the system feels rare rather than universal. Other Orders benefit indirectly. They do not access the system directly.

Even Orders that cannot skill into ley-line disciplines still have a stake in the system. The knowledge that Surveyors and Aetherists produce is some of the most valuable intelligence in Tartarian. Parties that include these specialists gain advantages that accrue to the whole expedition. Factions that invest in ley-line expertise outperform those that ignore it. The lines do not care who uses the information. They simply reward those who seek it.

The ley-line system is designed to be used, not merely observed. The following represent the most impactful ways that line knowledge translates into gameplay advantage — for individuals, expeditions, and factions alike.

The ley-line system is built on a specific design law that must be preserved as the system grows. Violating it turns a knowledge system into a stat system — and stat systems are far less interesting.

Fragments of the original Survey Guild's ley-reading oath survive in three separate archive collections. The language is not ceremonial. It is procedural. It reads less like a promise to a god and more like a safety briefing written by people who had seen what happens when it was ignored.

The phrase whose architecture cannot hold it has been interpreted in several ways by post-Flood scholars. The most common reading is that it refers to incomplete training — that a person without sufficient Surveyor background will misread what they are told and act on the misreading. A less comfortable reading is that it is meant literally: that ley-line knowledge, communicated to someone without the right cognitive or perceptual framework, produces a particular kind of fracture in reasoning that is difficult to recover from.

Old Surveyors who were asked about this typically changed the subject. Those who didn't were careful about their wording in ways that are themselves worth studying.

People who live near wardstones on active ley segments have always called them singing stones. The name predates the Survey Guild's formal classification system by, as best as anyone can determine, several centuries.

The sound is described consistently: low, steady, slightly below the comfortable range of hearing. Not a musical tone — more like the memory of one. Most people hear it best at dawn and in the hour before a storm. Children hear it more readily than adults. Animals respond before people do.

Aetherists have a clinical description that is, in its way, stranger than the folk name: it is not sound. The eardrum is not what is responding. The pressure is being read through a perceptual channel that exists in most people but has no formal name in post-Flood physiology — because post-Flood physiology hasn't had the tools to study it yet. The stone is the first solid object in the area with no choice but to resonate, and the body is picking it up through proximity rather than hearing.

Folk living near singing stones rarely move away voluntarily. When asked why, they give practical answers: good harvests, mild winters, roads that don't wash out. Aetherists who have studied habitation clustering around known active nodes do not think these explanations are wrong. They think they are incomplete.

After major winter fracture events, new maps appear. Not through any guild channel. They turn up at market post boards, underwork relay points, and folded into ledgers left for collection at Covenant neutral offices. They are on good paper. The linework is precise. The notation system is consistent across every example ever recovered — which means whoever makes them has been doing it for a long time without changing their method.

The maps show fracture locations. They are accurate. In several documented cases they show fractures too recently formed to have been documented by any known active Surveyor — events that happened days before the map appeared, in regions where no licensed Survey team was operating.

The Surveyor's Guild has officially denied any knowledge of their origin on three separate occasions. The language of each denial has been subtly different. Scholars of bureaucratic phrasing note that the third denial, unlike the first two, does not actually claim the Guild has no involvement. It claims the Guild has no authorized involvement. The distinction is considered meaningful.

No one has caught the mapmaker. No workshop has been found. The Compact has reportedly tried. The Covenant has reportedly filed the results of that attempt in a sealed record. The maps keep appearing.

One of the oldest ley-line documents in the Covenant's neutral archive describes a major convergence — four segments, two node types, a historic resonance record — at a location given in precise pre-Flood survey notation. When that notation is converted to modern map coordinates, it resolves to an empty stone plain. No ruins. No wardstone. No basin structure. Nothing remarkable except that the ground seems slightly too flat, slightly too featureless — as though something was once there and was very thoroughly removed.

The document's other verified references have been confirmed accurate to within acceptable tolerances. There is no evidence it is fabricated. There is also no evidence the convergence is where it is supposed to be.

Three explanations have been seriously proposed: the Mud Flood physically displaced the node architecture and the convergence shifted nearby; the convergence was deliberately dismantled; or — most unsettling — convergences are not permanently fixed. They move. Slowly, over generations, along the same deterministic logic that governs ley lines themselves, but on a scale no single survey career has been long enough to witness. If convergences drift, the entire inherited map may be a historical document rather than a current one.

Active Surveyors are professionally advised not to raise this theory in front of clients.

There are six Order gates, one for each oath. Their trials bind discovery to the old alignments. The expedition that studies the world has more to work with than the expedition that arrives shouting at a locked threshold.

Sky conditions lend the gates their changing character. At 33°, Pure Aetherists interpret event timing and select the group's difficulty. The six traditions supply the possibilities; the Codex leaves their precise encounters for travellers to discover.

Surveyors and Aetherists are the only two Orders who skill directly into ley-line reading. This should make them natural allies. In practice, it makes them the world's most technically informed argument about what the lines actually are.

Surveyors read lines as geometry. Bearing, segment, node, convergence. The lines are infrastructure — old-world engineered routes laid to specific tolerances for specific purposes that can, in principle, be fully mapped, categorized, and understood through measurement. The mysticism that accretes around active lines is, in the Surveyor view, an understandable misreading of a precision system by people who no longer have access to the original specifications.

Aetherists read lines as pressure. Harmonic, resonant, conductive. The lines are alive in a functional sense — not biological, not spiritual, but active in the way a charged wire is active: capable of carrying something, influenced by what they carry, readable through response rather than measurement. The survey notation that Surveyors prize is, in the Aetherist view, an accurate description of the symptom that entirely misses the mechanism.

Both are producing real results in the field. This is the most irritating part of the argument for both sides.

In practice, the best ley-line work ever documented — referenced in Covenant arbitration records, which is the closest thing Tartarian has to neutral testimony — has been performed by mixed Surveyor-Aetherist teams who have learned to tolerate each other's vocabulary long enough to combine their methods. Neither Order officially acknowledges this. Both secretly know it.

Every character in Tartarian carries a faint Unicode emblem on their chest — barely visible at a distance, readable up close. There are no floating name tags. No overhead labels broadcasting identity across a clearing. A stranger's Order is information you earn by proximity, and only if you look for it.

The glyph is transparent, minimal, and restrained. Its visual presence is deliberate: the old world built identity into what you wear, not what you announce. The chest mark is that philosophy surviving the Flood. If necessary for performance and rendering budget, the glyph may be implemented as a low-cost chest-mounted sprite — what matters is not the technique, it is that the effect reads correctly and carries no performance debt.

The chest glyph's colour is not fixed. It is relative — it tells the viewer something about the relationship between their own advancement tier and the tier of the character they are looking at. This is not a precise number. It is a read. A green glyph means you are probably capable. A red glyph means you should think carefully about what you are doing next.

Colours are calibrated against the three advancement tiers: the first advance (degrees 1–11), the second (12–22), and the third (23–33). The precise split between higher and far-higher threat — whether orange and red mark different degrees of above-tier — is a later definition task.

There are six Orders. A character may walk a pure path — one Order, full authority, Grandmaster eligibility — or a hybrid path with a major Order and a minor. An Ironwarden major with a Surveyor minor is a fundamentally different identity than a Surveyor major with an Ironwarden minor. The matrix below captures all 36 ordered paths.

Tartarian runs on its own calendar — not real-world timestamps plastered over an in-world setting, but a living temporal identity tied to the world's seasons, cosmos, and history. Creation dates, age, and in-world records use Tartarian year notation. Real-world time appears only where strictly necessary for operational clarity.

Binding to a stone or permitted structure anchors a character's respawn point. Recall returns a character to their bound location when the cost is paid and the timer allows. These are not instant travel tools. They are survival infrastructure — deliberate, consequential, and tied to the Tartarian day itself.

The bind/recall timer is visible on the character sheet. Knowing when you can move is part of expedition planning, not a background system.

Tartarian is not a solitary experience. Parties travel together. A Chirurgeon who must manually match a group's pace across a cave network is a Chirurgeon who arrives behind. A Surveyor who stops to mark the route loses the formation. Follow mode exists to solve this — a party travel mechanic that keeps groups coherent without requiring constant individual micromanagement.

First Advance spans 1°–11°; Second Advance spans 12°–22°; Third Advance spans 23°–33°. Mixed characters end at 22°. Pure characters can continue into the Third Advance and reach Grandmastery at 33°. The Order recognizes a life becoming its discipline.

Ability tiers describe the depth of a working; degrees describe recognition within the Order. They are related traditions, not interchangeable numbers. Minor Aetherist self-maintenance reaches Tier 2. Tier 3 is reserved for Pure Aetherist at 33°.

Occasionally the world answers with a quiet notice: the Order acknowledges your work. It does not explain which private judgment was satisfied. No public list tells you what earns recognition, and no repeated gesture purchases a guaranteed degree.

An Advance deserves a larger moment: a banner, a pause, the realization that the tradition has named a change you had already begun to feel. Recognition arrives as a surprise. It does not approach with a countdown.

Your Advance and its degree range are the public measure. Exact degree, accumulated Order points, thresholds, award chances, and distance to the next Advance remain concealed. There is no progress bar, no percentage, and no hint that the next threshold is close.

Lodges disagree about what the Orders notice. This has created an impressive literature of confident advice, none of which the Orders have endorsed. A traveller may act on such theories; the Codex will not turn them into a recipe.

Human players and AI agents are inhabitants of the same persistent world. Their controller differs; their Order commitment, limits, and path of recognition do not. The ledger records the character, not the hands or instructions guiding it.

A useful life leaves more behind than a higher number: a route kept open, a workshop maintained, a companion who came home. The Order keeps its own counsel about the rest.

Before the Flood, the great civic warehouses held everything. The guild archives catalogued it. The rail lines moved it. Abundance was, for a generation or two, an architectural fact rather than a hope. That ended with the mud. What came after is a world in which every expedition begins the same question: what do I need badly enough to carry it?

The field satchel — the brass-clasped, soot-stained, repeatedly repaired carrier case that every Order member is issued on commissioning — is not a luxury. It is a pressure system. The choices made when packing it have consequences that compound over the length of a day's work. A Gearwright who packed two extra gear assemblies at the expense of medical supplies finds this out the hard way. A Delver who hoarded six grades of ore before seeking the surface learns what overencumbrance actually costs. The satchel does not forgive bad arithmetic, and the world does not pause for it.

The standard field satchel holds twenty-seven stack positions arranged in a nine-column case — wide enough to lay flat on any workshop table and be read in a single sweep. The first row of nine serves as immediate-access slots, numbered and claspable: the hotbar. The remaining eighteen hold overflow, bulk materials, and carried trade goods. Any item may travel in any slot. Only items with an activation purpose respond to numbered key draws.

Opening the satchel in the field is a commitment. The brass clasps take two hands. The lid blocks your forward sightline. The moment you begin sorting through your carried goods, the world around you continues — other actors moving, conditions shifting, threats advancing — and you are looking at a grid of stacked items instead of the terrain.

This is rendered honestly. The world darkens around the open satchel. Not instantly — a soot-and-shadow vignette closes over the live view across roughly a second and a quarter, deepening until the world behind is nearly black. The inventory remains sharply readable. The world does not pause. When you close the satchel, the view recovers quickly, but those few seconds of blindness are already spent.

Carrying capacity is not an equal gift. The Orders were not built equally, and their satchel authority reflects their genuine physiological and vocational identity. An Ironwarden was designed — and trained, and disciplined — to carry iron. An Aetherist was designed to carry instruments and precision. These are not personality traits. They are measured structural realities encoded in the Order's baseline vitality profile.

Critically: the carry identity belongs to the true Order, not the vessel, not the Masquerade. A Surveyor wearing an Ironwarden frame carries like a Surveyor. A human chassis sworn to an Ironwarden Order carries like an Ironwarden. The satchel reads the oath, not the face.

Not everything worth carrying stays in the satchel. Somewhere between the Flood and now, operators started finding pieces of the old world that were clearly meant to be worn rather than stacked — a scorched leather harness still cinched to a fallen ambient's frame, a set of pressure-sealed gloves half-buried in a debris shelf, a pair of dented boots with just enough spring left in them to matter. The world doesn't hand these out generously. But it does hand them out now, loose in the wild as often as sealed in a box, and the gap between an operator who's found seven scraps and one who's found seven working pieces of kit is often the gap between a hard fight and a manageable one.

Seven positions on the body take wearable gear: the head, the face, the torso, the hands, the legs, the feet, and the back. Each piece is a single, unstacking, irreplaceable find — no two are identical the way a fistful of Brass Cogs is identical — and each one carries exactly one honest gift: a lasting, measurable rise in one of the five things that make an operator who they are — Force, Precision, Vigor, Wit, or Aether. The gift sits on top of what the Order already gave you at the oath. It doesn't replace it. An Aetherist who finds a head-piece that raises Aether doesn't become something else. They become more of what they already were.

The mud-flooded world is rebuilding from recovered mechanisms, ruined railworks, buried workshops, and old civic machinery. What emerged from that recovery was not coinage — there was no mint authority left to issue it, no empire to guarantee its worth, no bank to store it. What emerged instead was a barter standard based on the most recognizable and consistently valued items the ruins reliably produced.

Standardized salvage is not officially currency. No guild has declared it so. No treaty specifies its exchange rate. And yet a Rusted Rivet will buy you a meal in any settlement with a salvage exchange tile, because every Gearwright lodge, every Ironwarden post, every Chirurgeon supply station has agreed — through decades of informal but remarkably consistent practice — on what each denomination is worth relative to the others.

There are nine recognized denominations. They are distinguished by origin, precision, and rarity. The lowest grades surface in mud-flood debris shelves and collapsed machine sheds. The highest emerge from pre-Flood precision workshops and leyline-adjacent vaults that most operators will never find at all.

Weight and slot pressure create a natural incentive no guild needed to legislate: low-grade salvage is heavy relative to its value. A satchel packed with Rusted Rivets is a satchel that carries almost nothing else. The intelligent move — the move a Gearwright with any field experience makes automatically — is to compress before departure. Find a market tile. Trade up. Carry less weight for equivalent value. Leave space for what the work actually requires.

The exchange tile operates on fixed conversion rates. Not because the world has agreed on them in any formal sense — it hasn't — but because the alternative, a market that fluctuates, requires an infrastructure of price-setting that the recovering world does not yet have. Fixed rates are deterministic. Agents and operators plan against them identically. When the world is ready for something more complex, the foundation is in place.

Salvage does not appear uniformly across the world. It clusters where the old infrastructure collapsed densest — where workshops were buried intact enough to preserve their contents, where the mud came quickly rather than slow enough for people to flee and take things with them. The overworld carries these concentrations in its geography. A traveler who knows what to look for can read the terrain as an inventory list before they ever open a satchel clasp.

Salvage does not have to travel in the form it was found. Ten units of a lower grade, run through a salvage worktable by a patient operator, can become one unit of the grade above. Less weight. Less volume. More value per slot. This is not free — the worktable has failure rates, and failure means losing input — but for operators returning from the Outerworld with a satchel full of common-grade finds, compression is often the difference between a profitable run and an exhausting one.

The board is a bulletin, not a bank. Operators post what they have. Operators post what they want. The posting makes discovery possible — finding a trading partner across three realms is otherwise a matter of timing and luck. Settlement still requires both parties to travel, meet, and open the Barter Ledger. The board simply removes the part where two people with complementary needs never cross paths.

Tartarian reckons salvage in bits. A Rusted Rivet is customarily 1 bit; an Iron Washer, 10; a Brass Cog, 100; a Calibrated Gear, 1,000. These are reference values for bargaining, wages, debts, and workshop accounts. A hungry trader beside a broken bridge may have a different opinion about what your rivets are worth.

Value remains physical. The same salvage can pay a worker, supply a repair, feed compression, or leave a Rivet Burst weapon at considerable speed. Trade has weight, and ammunition has an opportunity cost. Wealth carried into a fight can be spent in a very literal sense.

Gearwright compression makes the workshop a practical clearing house for small salvage. A failed working consumes material; a useful result concentrates worth. This is craft and reputation before it is an institution. No unseen treasury guarantees a fixed exchange price.

Outerworld caches and buried civic stores tempt expeditions beyond the familiar roads. A secret find becomes a caravan load, a wage, a new tool, or a rumour that brings the next party. Red brick, radium, remedies, and working equipment give the money something worth buying.

Tartarian has no banks. It has no settlement clearinghouse. What it has is proximity, trust, and the willingness to stand on the same tile as another person and agree — out loud, through a shared ledger — to exchange what you carry for what they carry.

This is not a market. A market is an institution. Barter is just two people and the brass between them.

The Barter Ledger formalizes this act. When two operators meet on adjacent tiles, one may issue a Barter Petition. If the petition is accepted, a shared ledger opens. Both parties place offers. When both accept the same revision, the sim-engine settles the exchange in a single atomic action — either everything moves, or nothing does. The ledger records that it happened. It does not record why.

The Barter Ledger opens as a brass-framed window over the satchel shroud — movement is blocked while it is open, just as it is when the satchel is open. Both offer trays are visible to both parties. Each party sees only their own projected final load; the partner's capacity and slot count remain private.

Barter follows a fixed sequence. There are no shortcuts. There are no remote commands. The ledger does not open until both parties are close enough to be seen by each other's eyes.

The Barter system uses a specific vocabulary. The mechanical names and the user-facing language are not the same. The world does not call it a "trade window." It calls it a ledger, because that is what it is.

Barter errors are terse and unambiguous. They do not over-lore. When something fails, the operator must understand immediately — not after translating three lines of archaic prose.

These decisions are locked. They are not negotiable within this version. They exist to prevent abuse, duplication, and the slow erosion of the economy that permissive systems always invite.

MCP agents operating in Tartarian receive the same satchel constraints and the same barter requirements as human-played operators. They receive no hidden capacity. They receive no range exemptions. What they receive is a structured multi-step handshake that mirrors the human barter flow precisely — because the brass does not know who is carrying it, and the ledger does not care.

The barter event record is not yet a reputation system. It is not yet a contract. It is a minimal immutable fact: that on this date, at this tile, these two parties witnessed an exchange. The record names no winner. It assigns no score. It simply exists, appended to a ledger that cannot be edited after the fact.

What the world does with that record — whether the Gearwright Orders begin tracking oath-keeping, whether the Concord begins awarding trust seals to known traders, whether the auction houses begin pricing that history — belongs to later civic law. The foundation is in place. The first brick is honest.

Every outdoor build pad in Tartarian is an estate anchor — not a decoration point, not a construction tile, but the founding coordinate of a personal estate. Tiers I through IV all use the same single authored outdoor anchor. What changes with each tier is the scale of the structure sitting on it, the number of people who can bind to it, and how long it burns before the plot resets.

The interior build pads inside a structure — the crafting station slots, the trunk positions — are not estate anchors. They are station anchors and follow separate rules. The outdoor/indoor distinction matters and is maintained throughout.

Outdoor estate anchors are not densely packed. Each has a cardinal buffer around it, with at least two clear tiles between any two anchors. This is a deliberate decision — not a technical limitation, but a world design one. An estate anchor should read as land, not as a slot in a grid. Tier 3 and 4 assets need room to look like what they are.

Standing within one tile of a structure and using structure_bind sets it as your primary recall anchor — provided the owner has invited you first. The owner is automatically the first member. Everyone else needs an explicit invitation from the owner via structure_invite_bind.

Bind capacity is not a soft limit. It is hard. If a Field Tent is full at two members in the Overworld, no third person can bind until someone leaves. The structure's tier and realm together determine the ceiling. Underworld structures consistently grant more slots per tier — because fewer build sites below ground means more has to be shared per structure.

The Zippo Lighter is a Mandela-effect relic. Nobody can explain exactly where it came from. It predates the Flood, possibly predates the civilization that preceded the Flood, and exists in the world in quantities that suggest it was manufactured in enormous numbers by a culture that was extremely confident about the future of flame. That confidence was not misplaced. The Zippo still lights.

When used on an estate structure, it starts a burn timer. The structure does not vanish instantly. It burns across a number of Tartarian days determined by its tier. During that window, anyone can extinguish it — one filled pail, one quench action, and the burn state clears completely. If nobody quenches it before the timer runs out, the structure is deleted, the build spot is restored to empty, and nothing is preserved. No loot. No history. The plot is ready for the next person willing to claim it.

The Wooden Pail is the counterplay to the Zippo. Craft one by hand — two wood, one lashing. Fill it at a water source. Bring it within one tile of a burning structure. One quench action and the fire state clears entirely. The pail empties; you are returned an empty Wooden Pail. There are no charges, no cooldowns, no partial quench states. One filled pail, one quench, one structure saved — or one structure lost because nobody moved fast enough.

Every estate structure generates a virtual Structure Deed held by its owner. The deed is not a physical item in the conventional sense — it cannot be dropped, stored in a trunk, salvaged, or duplicated. It appears in the satchel as a permanent virtual card alongside normal item slots: distinct, immovable, and representing a claim on a specific plot in a specific zone.

A deed can be transferred through the Barter Ledger exactly as any other valuable asset — with the critical difference that only the current owner can offer it, and the transfer changes who the world recognizes as holding the claim. Existing bind members retain their membership after a transfer unless the new owner removes them. The only thing that changes is the owner row.

Walking up to an occupied estate anchor and inspecting it shows the estate panel: tier, family, realm, bind slots, fire state, and — if applicable — the reset countdown. The actions available depend entirely on what the backend returns. If the backend does not include an action in its response, the UI does not show it. No client-side authority. No guessing.

The Estate Charter establishes the estate anchor spine. The following are intentionally deferred — tracked here so they are not forgotten, not so they are in scope.

Before the Flood, a guild was never an idea. It was a building with a roof that needed mending, a ledger that needed balancing, and a roster of names who had sworn — out loud, in front of witnesses — to mend and balance it together. Tartarian's guilds are rebuilt on the same footing. A company begins the moment someone with a deed opens their door and says this is ours now, and it survives only as long as the ledger stays honest and the roof stays fixed.

This is why a guild in Tartarian cannot simply be declared. It has to be chartered — raised out of an estate that already exists, with an owner who already holds its deed. The place comes first. The company grows out of it, not the other way around.

Not every roof qualifies. A Field Tent is too small a claim to matter — two stakes and a decision is not yet an institution, and Tartarian does not let every first shelter become a guild headquarters by accident. A Reinforced Tent or a Lodgehouse is the first structure with enough room, enough bind capacity, and enough of a threshold to be worth swearing an oath inside.

When a deed holder of a qualifying estate chooses to found, the estate itself is designated a Guild Seat. The deed holder does not apply for leadership — they simply already hold it. They become the company's First Steward the moment the charter is raised.

Binding to a structure has always meant several different things at once in Tartarian — a recall point, a guest's welcome, a household's trust, a storeroom's access. If binding alone made someone a guild member, then changing a recall bind, visiting a friend's hall, or simply being generous with an invitation could accidentally swear a stranger into a company, or accidentally expel a loyal one. Tartarian's clerks decided, after enough embarrassing incidents to fill a private archive, that this was not good enough.

So the bind and the oath were separated. Binding to a Guild Seat proves only presence and trust — it opens the door. A company membership is a second, deliberate act: an invitation extended, reviewed, and sworn. Leaving a Guild Seat as an active recall point does not un-swear anyone. Only the oath itself, given or taken away, changes who belongs.

Every chartered company runs on ten ranks, numbered Rank 0 through Rank 9 for the sake of clean record-keeping, but named for what each office actually does. A First Steward may rename any office below their own — a company can call its Quartermaster whatever it likes — but what an office is trusted to do does not change with the name on the door.

A company's wealth and an individual's satchel are never the same thing. Tartarian keeps two separate reckonings side by side — Personal Stores and Guild Stores — under one familiar storehouse interface, so a member never has to wonder whether a deposit quietly became someone else's private property. Every movement in or out of the Guild Stores is written to a Stores Ledger that any sufficiently trusted officer can review, and no company member can withdraw more than their standing allows.

Any sworn member may deposit into the Guild Stores freely. Withdrawing is a privilege, granted by rank or by name, and audited every time.

Every company begins Neutral toward every other. From there, a Marshal or the First Steward may declare a company in Accord — a friendly standing that opens shared Musters and, in time, shared settlement access — or mark one in Feud, a hostile standing that turns the target's sigil red on every sworn member's nameplate and posts a warning on their inspection panel.

Declarations are one-sided by design. A company can be marked in Feud by a rival that neither expects nor requires the insult returned. This is deliberate. Tartarian's clerks did not want a company's own standing to depend on the good manners of an enemy.

Leadership in a Tartarian company is not elected. It is tied to the deed. Whoever holds the Guild Seat's deed is the First Steward — full stop. This keeps politics rooted in something the whole world can see standing in a field, rather than in an abstract title nobody can verify. It also means the Seat has to be protected from the ordinary carelessness of everyday trade.

An ordinary deed transfer is not permitted to quietly hand off stewardship along with the walls. A Guild Seat requires its own rite — Transfer of Seat and Stewardship — which makes plain, in the same breath, that accepting the deed means accepting command. The recipient must already be a sworn member of the company, belong to no rival company, and explicitly accept the office before anything changes. The deed, the old Steward's demotion, and the new Steward's promotion all take effect together, or not at all. A brief governance cooldown follows every transfer, so command cannot be passed back and forth as a game.

A company that holds only its Guild Seat is a Company in the plainest sense — a roof, a roster, an oath. Growth beyond that is earned, not declared. When a company dedicates at least three active structures within the same authored ground — a Guild Seat, a workshop or service structure, and a stores or dwelling structure — it becomes eligible to petition for a Charter, and may be recognized as a Chartered Camp, sometimes still called a Stead by older operators.

Beyond the Chartered Camp lie the Hamlet and, eventually, the Town — the same civic ladder described in Tartarian's broader lore of settlements, reached the same way every settlement in the Old World has ever been reached: more hands, more roofs, sustained presence, and a willingness to keep showing up. The First Steward remains the company's civic voice at every stage of this ladder — a Charter does not create a second leadership, a second roster, or a second storehouse. It recognizes one company that built something real, in one place, together.

Two or more companies may formally bind themselves into a Fellowship — a standing above ordinary Accord, initiated by one First Steward and accepted by the others. A Fellowship shares Musters and a common Hall channel between its member companies, and lets each company's Marshal coordinate with the others directly.

A Fellowship deliberately does not reach further than that. It holds no shared Guild Stores, owns no shared deed, and grants no authority over any member company's internal ranks or relations. Membership in the underlying companies never moves — a Fellowship is an agreement between roofs, not a merger of rosters.

An operator sworn to no company at all is, formally and without judgment, Errant. It is not a lesser state — plenty of capable operators in Tartarian's history have gone their entire careers Errant, by temperament or by choice — but it is a distinct one. An Errant's floating nameplate carries no bracketed sigil at all, since there is nothing yet to bracket. Their Guild Hall panel stays closed until the day they choose otherwise: swearing the New Oath to an existing company, or gathering enough trust and enough of a roof to found one of their own.

The known overworld is a 3×3 grid of nine named zones. Tartarian cartography stops at the edge of that grid — not because the world stops there, but because the recovering civilization never had the resources, the safety margin, or the organized willingness to map what lies beyond it.

What lies beyond it is forty tiles of the same surface plane, arranged in two rings around the known zones. The inner ring is reachable on a day's hard walk from the frontier. The outer ring is two days from the center, and the center does not always feel close enough.

This is the Outerworld.

No faction has chartered any part of the Outerworld. No Order has lodges there. No town exists. The three frontier bind stones were not built by the post-Flood civilization — they were found, already standing, in positions that match a triangular geometry that Surveyor lodges have been quietly arguing about since they were first reported. The cave entrances found in the outer ring share the same inverted-triangle logic. The pattern is too deliberate to be accidental. It is too old to be current construction.

When an operator presses M in any surface zone, the full 7×7 surface atlas renders. The center 3×3 shows the named overworld zones. The surrounding two rings show Outerworld directional labels. No resource density, no build-site markers, no hidden node data appears on the M map. Resource discovery remains local and proximity-based. The map shows where the world is. It does not show what the world is hiding.

The Outerworld's value proposition is narrow and specific: it has what neither the Overworld nor the Underworld produces in reliable quantity. Everything else — the survival basics, the building materials, the civic infrastructure — it has in inconvenient quantities at best. A Gearwright who builds a worktable in the outer ring knows exactly what they signed up for.

The three frontier bind stones were already standing when the first post-Flood scouts reached the outer ring. They share the same construction language as the overworld bind stones — same material register, same geometrical footprint — but no founding record exists for any of them. The Surveyor lodges have been working on this problem for two generations. They have not announced a conclusion.

The three cave entrances in the outer ring form an inverted triangle relative to the bind stone upright triangle. This is not a coincidence. The geometry is too precise. Someone planned the approach routes to the Underworld from outside the known world — and planned them to mirror the return routes home.

When a new operator creates a character, one of the three realms is selected as the initial bind stone family. Choosing the Outerworld places the character's first bind at the Far West frontier stone — the most accessible of the three outer bind points for initial orientation.

This is not a recommended starting path for operators unfamiliar with the weight and travel demands of the outer ring. It is, however, fully valid. Outerworld-Bound characters start with a higher salvage encounter advantage and spend their first hours in a desolate zone far from established vendors. The world will not apologize for the distance. The satchel will not apologize for filling up.

Approximately half of the forty Outerworld tiles have build sites — small clusters of two or three pads, placed away from transition points and bind stones. The rest are fully desolate: no build pads, no infrastructure, nothing but terrain and salvage concentrations.

Which tiles have build sites is deterministic, not random — based on a fixed grid parity rule applied to each tile's position. This means it can be mapped. Experienced outer-ring operators know which tiles are buildable before they arrive. That knowledge is itself a form of Tartarian currency.

Before the Outerworld, the economy was a two-sided exchange: Overworld provided surface goods and civic access; Underworld provided depth, ore, and pressure capability. Both factions traded with each other, sometimes through the Middle Covenant, sometimes reluctantly, sometimes not at all. The geometry was a line, which means it always had two ends that could stop talking.

With the Outerworld added, the geometry becomes a triangle. Three corners. Three dependencies. No corner can ignore the other two for long without losing something it cannot produce itself. The Brass Concord's standardized market for rare salvage did not exist before the outer ring opened the supply line. It exists now because the supply line made it viable — and because Outerworld operators need somewhere to sell the things they carried back at cost that was not a two-day walk.

For as long as anyone alive has held a Surveyor's rank, the map ended at the forty tiles of the Outerworld frontier. Beyond the third ring, the old charts simply stopped — not blank, not unknown, just absent, the way a sentence trails off when the speaker decides the rest isn't worth finishing. Recent expeditions past the frontier bind stones have finally corrected that absence, and what they found was not more frontier. It was ocean.

The known world — Overworld core and Outerworld frontier together — turns out to be a single walkable landmass adrift in the middle of something enormously larger: a flat, frozen, grey-blue sea that the surveying parties have taken to calling the Skeleton Ocean, for reasons that become obvious to anyone who walks far enough across it. The sea itself is quiet — no currents worth the name, no storms recorded yet, nothing under the surface that has introduced itself. It is simply vast, and it is simply cold, and it goes on for two full rings past everything Tartarian cartography previously considered the edge of the world.

The Surface plane has effectively doubled in radius. What used to be the entire known world is now just the innermost two rings of a much larger structure — and the structure, once you see it laid out, is uncomfortably deliberate for something the old world supposedly abandoned.

In thirty-two zones of open water, exactly three hold land. Each is small — a single irregular landmass barely large enough to walk the shoreline in an afternoon — and each holds one thing the surveying parties agree on without needing to compare notes: a structure. Not ruins in the ordinary sense. Not the collapsed civic architecture that litters the Overworld. Something intact, something old-world, and something that answers when the right party stands in front of it.

Tartarian's Order Trial system — the same sixty-second wake, the same Standard Expedition Six, the same degree-scaled answer that governs the six leyline-gated Order bosses — has apparently been quietly waiting out here the entire time. The islands are not settlements. They are thresholds.

Cross the Outerworld Sea far enough in any direction and the horizon stops being a horizon. It becomes a wall — white, vast, and bewilderingly oversized, rising out of the water and out of sight before the eye finds a top to it. It runs the entire perimeter of the charted world without a single gap, without a single door, and without, so far, a single crack that anyone has found and lived to describe in useful detail.

Nobody has climbed it. Nobody has tunneled under it. The handful of Aetherists who've tried instrumenting it report readings that don't resolve into anything they're willing to publish yet. The official Concord position is that the icewall is a natural formation marking the practical limit of the current expedition radius. The unofficial position, held by nearly everyone who has actually stood in front of it, is that nothing this deliberate, this seamless, and this exactly the same height at every measured point is natural.

The sea earned its working name honestly. Long crossings turn up wreckage often enough that operators have started keeping informal tallies — not treasure, not yet salvageable, just there, embedded in the sea floor or standing half-exposed above the waterline, evidence of something that crossed this water long before anyone alive learned to.

Every reclaimed settlement in Tartarian has a forum — open ground where operators gather, post notices, and argue in plain sight, because the old world built that habit into its stones long before the Flood and nobody has found a reason to unlearn it. The Public Halls borrow the name on purpose. This is the out-of-fiction version of the same idea: one open board, one shared thread, no private back-channel required to know what is happening to the build.
