The world has been shattered, shifted, and rebuilt with the passing of each era. Long dynasties, continental empires, heroes among heroes, felled by the Champions of the Beyond to usher change. An era dominated by true monsters, an era where power is absolute, an era where humanity is at its edge from the apex predators of the period. Monsters unlike anything that the world has seen, machines of precision⁠; merciless with endless ambitions ⁠— Dungeons.

Once again, a new Champion is selected by the now fading power of the Beyond. Leah. A just formed Dungeon with fragmented memories of a different life and world, a Dungeon with the memories of a human of a different realm. She must learn the harsh reality of what this new world is while trying to stay alive, and more importantly, find out what she is.
