Aetherium Hearts

Send them down and wait. They walk the labyrinth on their own feet, fight, and sometimes do not come back. Those who do bring back the tale of it.

Raise adventurers in Selwyn, town of the Ash Marches, and send them down into the labyrinths. The expedition runs by itself — they walk, they fight, they gather, and sometimes they fall. Those who come back bring the whole of it with them, written up by an AI as a single tale. No two are ever the same.

◆ Three labyrinths The Ashen Corridor, the Frostcrystal Archive, the Ember Crucible. Each runs to a different depth and a different danger, and at the bottom of each an Aetherium Heart lies sleeping.

◆ It runs on its own Once they are down there, they walk and fight on their own feet. The descent continues while the app is closed.

◆ Tales The record of a returning expedition is woven into prose by an AI. Send it straight to X, Threads, Bluesky or Discord.

◆ The town and your company An armoury, a general store, a forge, the guild, a temple, a shrine — Selwyn holds nine places to go. You can also go looking for an adventurer who has gone missing.

◆ Standings Set the Aetherium Hearts you have offered at the Shrine of Astel against every adventurer in every town.
