Aurora, a reincarnated Demon King, awakens in a vast underground world with a single goal: create the ultimate dungeon and crush the human kingdom that destroyed him in his former life. Using magic, traps, summoned monsters, and demonic contracts, Aurora begins constructing a labyrinth designed to lure, test, and annihilate invading adventurers.
As he recruits deadly women, enslaved spirits, and powerful demonic allies, Aurora steadily expands his underground empire—each new floor built with strategy, cruelty, and obsessive precision. Meanwhile, the surface kingdom mobilizes knights, priests, and heroes to destroy him again, unaware of how quickly the dungeon is evolving.
How to Build a Dungeon blends dark fantasy, dungeon-construction strategy, political scheming, magical warfare, and morally gray worldbuilding, focusing on a villain protagonist’s rise to power.
