Forgotten Temple of Tharizdun
Gary Gygax
 The Forgotten Temple of Tharizdun is set in the World of Greyhawk. The player characters (PCs) follow a band of marauding norkers from the caverns, discovering the temple along the way. They must search through the dangerous mountain passes to find the norker lair inside the temple. The adventurers are drawn into the story by a gnomish community and travel to the temple. After battling their way in, the PCs explore the temple chambers, which contain mundane creatures and new monsters from the Fiend Folio supplement. During their exploration, the characters may reach chambers of the temple in which religious rituals were performed, and risk insanity and death as they encounter remnants of worshipers of the imprisoned god Tharizdun. To progress further, the characters must enact portions of the rituals of worship of Tharizdun, traveling into an underground sub-temple, and magically opening an inner sanctum called the Black Cyst. Having advanced this far, the characters are likely to be driven insane, killed outright, or permanently trapped within the underground temple.
