Play in an AI world that actually stays put.

You ask an AI for a fantasy world and it delivers: a mist-wrapped coastline, a capital carved into a cliff, a rival kingdom three days east across the salt flats. It is a great start. Then you play for an hour, and the salt flats are suddenly to the north, the coast is inland, and the three-day ride takes an afternoon. The world was never really a place. It was a description that changed every time the story looked away.

An AI writes each scene from a window of recent text, and once your adventure outgrows it, the details that anchored the map fall out: which town was north of the river, how far the mountains were, which road led where. Ask where the capital is twice, an hour apart, and you can get two different answers, because nothing recorded the first one. (The full mechanics are on the AI RPG memory page.)

A world that holds together needs its geography stored as fixed data outside that window. That is what the map below is.

Auferet keeps a world map: an endless plane of named locations, each with fixed coordinates. As places are discovered or established in your story, the game master writes them onto the map, and from then on it reads from the map instead of guessing. The capital sits where it was placed. The rival kingdom stays east.

Because every location has real coordinates, the game master can compute the exact straight-line distance and compass direction between any two of them. A two-day ride stays a two-day ride. When you set out north, you arrive at what is actually north. Travel stops being a vibe and becomes something the world can measure, which is what makes a journey across your setting feel like crossing an actual place rather than teleporting between descriptions.

The map works underneath the storytelling. The game master still narrates the road, the weather, and who you meet, but on top of a geography that is fixed and looked up rather than re-invented each turn. That is the difference between a world you read about once and a world you can explore for a hundred sessions.

The flow is simple. You tell Auferet the kind of world you want, from a drowned city of canals to a frontier moon colony, and it generates a starting setting and a scenario to begin in. From your first steps, the places you visit are recorded on the persistent world map, so the geography starts stable and stays that way.

As you play, the world fills in. New towns, ruins, and landmarks get their own coordinates the moment they matter, world facts collect in the Event Library, and the people you meet are kept in the Character Library so they return later with their history intact. If you already have a setting of your own, upload it and play inside your own canon instead of a world the AI invented on the fly.

Here is what that looks like in a real play, not a description of one. On 2026-09-10, on the free-tier model, a fresh account started from one line, "I'm a royal courier riding out from the cliff-carved capital with a sealed letter for the rival kingdom three days east across the salt flats", and rode three turns. This is the map the Game Master wrote into the save while it narrated, read back from the save file, unedited:

Three turns in, the map holds the two places the courier actually stopped at. Asked how far the ride had been and which way the capital lay, the Game Master took the distance from the map, 150 cells due east at one mile each, and the capital's direction from the story, since the capital had been described in the opening but never placed:

The whole play, every turn and the map as saved, is published as a JSON file. What the map holds, it measures; what only the story holds, it narrates, and a place goes on the map the moment the story makes it one. The honest test is the one that catches most tools: travel across your world, then double back. If north is still north and the far city is still the same distance away, the world is real.
