From publisher blurb:
This is the Crypts section of the Palace of 1001 Rooms. It contains rooms 601-700 of The Palace of 1001 Rooms.
This is a module for Dungeons & Dragons gaming systems. The concept is a magical and mysterious palace in the clouds, accessible from many worlds, whose rooms are all connected by portals that lead to random locations within the palace. It's a ready-to-go, off-the-shelf, mega-dungeon romp for 1st - 20th level characters, with a lot of old 2nd and 1st edition content presented in a generic, non edition-specific format. Players or DMs roll a d100 to determine the room they're in and there is a corresponding page number in the pdf. It's a 1:1 match, so a roll of 53 sends the DM and players to page 53 of the pdf, where the details of that room are shown along with an illustration.
