I have recently been prepping a two level, 37 location dungeon lair - the rooms are a combination of natural caverns and pieces of sunken buildings of an ancient city broken apart and then reconnected by the current occupants' digging. Parts of it are unstable, parts show signs of work, heck in some places the PCs might be able to dig through walls to do their own renovations! I've got cultist patrols, a cellblock, a sunken church to a sloth god, and flooded chambers, a pump room run by zombies etc. . .
