Aetherium Hearts

In Selwyn, a town at the edge of the Ash Marches, raise adventurers and send them down into the labyrinth. The dive unfolds on its own — your adventurer walks, fights, and either returns or does not — and you can close the app while it runs. When they come home, an AI weaves what happened into a short tale, one telling for every dive, never quite the same twice.

◆ Three labyrinths The Ashen Corridor, the Frostcrystal Archive, and the Ember Crucible, each with its own depth and danger. At the bottom of each waits an Aetherium Heart.

◆ Automatic exploration Send an adventurer in and they explore on their own. Progress continues even while the app is closed.

◆ A tale of every journey Read what happened as prose, written by AI from the events of that dive. Share it straight to X, Threads, Bluesky, or Discord.

◆ A town and its people Eight facilities stand in and around Selwyn — armory, sundries, forge, guild, inn, temple, shrine, library. Adventurers who go missing can be sought and brought home.

◆ A world ranking Hearts offered at the Shrine of Astel are counted and ranked against every other town's adventurers.
