My entry to the One Page Dungeon Contest. I tried to incorporate player choice into it from the very first room. I'm afraid I may have added too much detail based on my own "story" of how characters might encounter this place. I think what made adventures B1 and B2 work so well was the room to fill in your own details and fit them into your world. I'd like to try running a party through it and make some revisions based on how that goes.
I envisioned this for lower level parties. They'll get wet, miserable, and, if the treasure is adjusted appropriately, rich.
