From the introduction:
The great Wizard Cull is a hero to the peasants and nobles alike, a man of honor who saves all those in need.
Little do they know, he has a darker side. The Magic User is a worshipper of Chaos, and uses his immense power and wealth to play games on unsuspecting travelers. The Labyrinth is his oldest game.
Discovered underneath his tall tower in the Hinterlands, the dungeon has been stocked with many terrible foes for Cull’s endless games.
If you can escape, great riches will be your reward. But if you cannot break free of this terrible place, your corpse will become just another on the pile!
