Ambermead is a small English village in the 1350s, a few years after the Black Death emptied half its houses. It runs on its own clock. A day in the village lasts 48 minutes, and it goes on whether or not anyone is watching. You're an unseen visitor: walk anywhere, go inside, look around.
The village keeps real books. Every household farms its strips in the three open fields, keeps its beasts, pays rent and tithe, and lives off what's in the barn. Harvests go well or badly with the weather. People are born, marry, fall ill, grow old and die.
Each villager has a mind of their own. A small AI model plans each person's day and writes what's said when two of them meet. They have their own natures, likes and grudges, and they remember what they've been told. Claude writes who each of them is and the village's daily chronicle.
Everything you see is made in code: the land, the buildings, the weather, the animals. The Chronicle has the village's news, who lives here, and each person's diary.
