In honor of the gaming luminary Jennell Jaquays, the C.R.A.M.P.S. Dungeon of Sin and Madness takes a factional wing approach to level design. The dungeon is designed on small form grid paper, a massive 70-room complex with tons of secret doors, treasure, unique encounters, and looping paths. It is designed for use with OSE but should work with any standard fantasy RPG system.
The design challenge for me here was to populate a 70-room dungeon on a single face of letter-sized paper and still be able to read it. There is much implied and lots for the DM to fill in with their imagination, but the heart is there for all the ideas I wanted to inject. I hope you have fun reading it, and I hope your players enjoy exploring it.
