The cult of the devil lords has fallen, and their temple disappeared along with them, punished by the fiends for imprisoning one of their kind. The crypts where the temple once was fell apart, and only the dead roam them now... The dead and the devil, waiting, imprisoned, for someone to cross the threshold once more.
Open the Crypt of the Fallen Cult where the worshipers of evil once performed their wicked rituals and uncover the truth about the cult's sudden disappearance. Did forces of good wipe them out... or did one of their deals with the devil turned to be more than they bargained for?
Crypt of the Fallen Cult is a one-shot dungeon crawl for parties at level 3 (or 5) for the 5th and 3.5 editions! Featuring new monsters and a multitude of puzzles and obstacles for players to overcome, it can be easily dropped in into any urban or horror-themed adventure as a point of interest, where adventurers could discover occult-related items, or find forbidden knowledge.
