This is one of the modules from the Dungeons & Dragons campaign that I ran, in case anyone's interested. It uses ascending AC.
The text is here (Word document), and the map is here (jpg).
The appearance of the wicked priests, and the miniature city, are by Aaron Somerville. I got them from issue 7 of Fight On! The giant arm is based on this. The stone faces are by ragnorakk from the odd74 forum.
EDIT: I've changed the link to the map, after some people reported problems downloading it.
