Synopsis

In a world forever altered by a cataclysmic war between the surface and the depths, humanity must co-exist with dungeon babies—mysterious individuals born with superhuman abilities and an insatiable draw to the subterranean labyrinths. Kim Jin-U is one such child. Yet, yearning for a peaceful life, he successfully suppresses his primal urges, choosing instead to work as a humble dungeon guide to support his beloved family.

But fate refuses to let his talents waste away. When a routine expedition spirals into a catastrophic disaster, Jin-U is thrust into the ultimate trial. Through a twist of destiny, he inherits the ownership of a sprawling, dangerous labyrinth. Now a Dungeon Lord, Jin-U can no longer run from the call of the deep. To survive the ruthless politics of the underground and protect those he loves, he must embrace his long-buried instincts, conquer rival territories, and build the ultimate subterranean empire. Will he remain master of his destiny, or will the abyss consume him?
