About this game
Dungeons Are Not Meant to Be Invaded
You are not a hero exploring a dungeon.
You have become the one who builds it, manages it, and keeps it alive.
As a minion who escaped from the Creator,
you establish a new dungeon and rise as its king.
Adventurers, drawn by rumors, see it as nothing more than a “low-level dungeon” and invade.
Your mission is simple.
Summon monsters, design your dungeon,
and decide where adventurers die—and where they retreat.
