Adapted from the underground-dungeon game classic Wizardry Variants Daphne, this story uses a simplified D&D setting. You can think of it as a light novel similar to Goblin Slayer.
Once every hundred years, the Gate of the Abyss opens, and the "Curse of Death" sweeps across the continent. Fiends that feed on death run rampant, plunging the world into despair. The king, whose line has sealed the gate for generations, vanishes under mysterious circumstances. The royal pact crumbles, and resistance becomes increasingly futile.
Aysin awakens as an amnesiac undead protagonist. His right hand manifests the power to turn back time, allowing him to repair ruins and awaken bones. In the labyrinth, he encounters Lulunade, a girl only he can see, and joins forces with the heir to the throne, Prugrit, the knight commander Dilenhart, and others. Together, they seek to recover his memories and uncover the truth behind the fiend's curse.
