Lair of the Possessed Otyugh
Luke used this dungeon to run an impromptu one-on-one RPG session over IM, and posted his APon the Story Games forum. His descriptions are perfect, far better than anything I planned to write for this dungeon, for example:
You are in the Lair of the Possessed Otyugh. You are standing in the rubble of a partially collapsed tunnel. Ahead of you is a door. You pry open the jammed door and... Enter the Preparation Room. The room is lit by guttering tallow lanterns. Tables covered in jars line the room. A slab for embalming bodies rests in the center of the room. A corridor leaves ahead of you and another entrance on your left leads to a small room.
And the climactic encounter later:
A mountain of refuse and offal cascades from the back wall down over the altar into a viscous pit in the center of the chamber. There are four vestibules, two on the left wall, two on the right. They lead to the murder holes. At the top of the refuse pile is an opening. Water runs from the opening down into the pit. A ghoul cultist stands atop the pile, shovelling garbage down into the pit. The pit contains a writhing mass of flesh and tentacles, “FEEEEDMMME.” it bellows. “YOUR GOD HUNGERS.”
