Aetherium Hearts vs Emberkeeper

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. Japanese and English, switching with your device. Free to play, with no in-app purchases.

Long ago, at the end of this road, stood a kingdom whose fire never went out. But the fire died, and the kingdom turned to ash. You are the knight who keeps the ember. The Emberkeeper. Fall, and you rise again beside this fire. If the fire dies, you stop. ■ While the fire burns, the knight walks on Keep the ember fed and your knight walks the road, cuts down foes, and challenges the bosses. While the fire burns, close the app and the march continues. Turn on notifications and you are told before it dies. ■ Read the tells, pack the cure Every boss has its tells and its weakness. One fears fire, one drinks blood to heal, one lays curses. Bring the right weapon and tools and you can win. Ignore them and you will fall, again and again. ■ What goes on your belt? Potions are your knight's fuel. Firebombs, purifying incense, whetstones, shield oil. What you send along decides the fight. ■ Fall. Rise. Grow stronger. Fall, and the wounds you left on the boss remain. The shards you earned scatter where you fell. Go back and reclaim them. Spend them on vigor and strength, and infuse your blade with fire or blood. There is no ceiling. ■ Two kingdoms, ten bosses Five in the Kingdom of Ash, five in the Sunken Royal City. From the ruined gate to the burning abyss, from the flooded streets to the black trench. From the Ashen Gatekeeper to the Abyssal Leviathan. Come back before the ember dies.
