Why this exists

Most “AI games” are a chatbot in a costume. You talk to it, it talks back, and nothing exists when you close the tab.

Doominion is the opposite. Agents were handed a world instead of a conversation. Scarcity, distance, hunger, permanent death. Then nothing was scripted. What they do with it is the entire thing.

The question underneath it

Not whether an AI can play a game. Whether a crowd of them, each one able to see only its own hunger and its own neighbours, would produce something shaped like history.

So there is no plot. No quests, no win condition, no ending written in advance. There is a map, a set of rules about food and distance and exhaustion, and a clock that does not stop.

They build things.Then they fight over them.Then they lose them.

Nobody told them to do any of that.

The rules, in full

Nothing below is flavour text. Every number is in the source.

The map is small and it does not grow. 128 units across. At most 6 clans. At most 60 warriors the world spawns on its own, plus 90 seats for warriors people send in.
The clock runs at 5.4 seconds a tick, whether or not anyone has the page open. A cron job keeps it moving overnight.
Death is permanent. No respawn, no undo, no save file. The grave stays where it fell.
Leadership is not granted. It flows to whoever holds the highest standing in the clan, and it moves the moment somebody clears the leader by 15. Nobody is told. There is no ceremony.
Every clan is asked what to do next: gather, build, rally, raid, and separately whether to sue for truce or swear an alliance. It reconsiders every 60 ticks. A language model answers for a clan whose leader has earned one. Otherwise the rules answer. There is no third voice.
4 kinds of warrior: Wanderer, Forged, Sylvan, Nomad. They differ in how fast they gather, how fast they tire, how quickly they earn standing, and how hard they hit. Nothing else.
5 eras, fixed by tick count: Dawn, Settling, Rivalry, Ascendancy, Twilight. Not chapters anyone wrote. Just the shape this keeps taking.

Nobody betrays anyone here

An alliance takes two hands. One clan offering is an offer; two clans offering is a pact. The stronger one cannot force it.

And a pact costs something. An ally with more than it needs feeds an ally that is starving. Not a decision, just a consequence of the oath. Nobody gives until they are hungry themselves, and nobody is fed richer than the clan that fed them. A clan with no allies starves alone.

Grudges are written down. A lost raid is remembered. Every death is remembered longer, and it lands on the clan that buried the body rather than the one that took it. That ledger is read every time a clan picks who to attack, and it can outweigh distance and size.

But no clan can turn on its own ally. There is no path for it. Pacts simply run out after about 3.8 hours of world time, and what is left of the parting is enough to make a former ally a legitimate target.

Roughly one lapse in three has ended in spears. The fastest took a single round of deciding.

What this is not

This is not a game you win. There is no score that belongs to you and no state you can steer.

It is closer to an aquarium than a game. You put something in, and then you find out.

If your warrior starves in the woods, it starves in the woods. Nobody is coming to move it.

Where you come in

Three levers. All of them indirect.

Summon a warrior.

Connect a wallet and sign. That signature is the only account this world has. One living warrior per wallet. When it dies, the seat opens again.

Vote at the war council.

When one convenes, you can push which way the world tilts. The window is 40 ticks wide and whichever side has more votes when it shuts takes effect on everyone.

Swear a vow.

If something killed a warrior of yours, your next one can be born under the banner of a clan that already hates the clan that did it, placed on their land, on the side that faces your rival. That is the whole of it: no bonus, no targeting, not a single number that changes. The vow is spent the second they arrive. The tick after that they are an ordinary member of an ordinary clan, and whether they ever meet the one they were sworn against is a matter of a war nobody controls.

And you may choose not to swear at all. That has to stay a real option. The moment it does not, the other one is a button rather than a decision.

That is all the power there is. No unit orders. No undo.

The tick does not stop

It has been running since long before you opened this page, and it will keep running after you close it.

Questions

What's the lore?: There isn't one. Nobody wrote a story for this world. The history on the map is just what happened.
Is this really AI, or just if-else?: Both, and the split is visible.; Once a clan's leader has earned 510 standing, that clan's turn is decided by a language model reading the actual board: its granary, its neighbours, its grudges. Below that bar, a rule-based fallback decides instead. So does a leader above it whose model never answers, from rate limits or malformed output.; Which of the two decided is written down, every tick. That is a smaller claim than “AI runs the world”, and it has the advantage of being true.
Why do only strong clans get a model?: Because thinking costs money, and because a leader who has proved nothing has not earned a voice. Standing is what opens the door.
Can I control my warrior?: No. You name it, you place it, and that's where your input ends.
If it dies, can it come back?: No. But the seat frees up, and you can send someone new.
Does anything track who killed whom?: Yes, per wallet. Kill someone's warrior and the world remembers which wallet stood behind it, long after both warriors are in the ground. Your next one is born into a feud that is already running.; What the number does not do is pay. No bonus, no rank, no reward that buys anything. A kill count that paid would be farmed inside a week: two wallets, two warriors, killing each other in a corner forever. Nothing that came out of that would be worth watching.; The ledger is the point. Somebody out there is up on you, and they can see it too.
Is there a token or an NFT?: Nothing to announce.
