Monsters have been threatening a nearby town, and a novice dungeon maker has a plan: build a dungeon in the adjacent caverns to lure the creatures away from the settlement. What the demons find enticing, you can also learn to exploit — venture inside, hunt what you've drawn in, and keep the town safe. As the dungeon grows deeper and more elaborate, increasingly powerful creatures move in, culminating in the hoped-for arrival of the legendary Wandering Demon — whose defeat would finally bring lasting peace to the region.
