Tharizdun

In the Dungeons & Dragons fantasy roleplaying game, Tharizdun is the god of Eternal Darkness, Decay, Entropy, Malign Knowledge, Insanity, and Cold. He originated in the World of Greyhawk campaign setting but has since also appeared in other settings. He was imprisoned ages ago by a coalition of deities to prevent the destruction of existence itself. Although imprisoned, Tharizdun still has a degree of his original multiverse-threatening power. His holy symbols are a dark spiral rune and a two-tiered inverted ziggurat known as an obex. His holy number is 333. Publication history Created by Gary Gygax based on Robert J. Kuntz's dark god "Tharzduun", Tharizdun first appeared in the module Forgotten Temple of Tharizdun. He would later appear in Gygax's series of Gord novels. Writer Michal Tresca speculated that Tharizdun might have been inspired by Clark Ashton Smith's Demon Lord and ruler of the Seven Hells, Thasaidon, who appeared first in The Tomb-Spawn, Weird Tales, Vol. 23, No. 5, May 1934. Advanced Dungeons & Dragons 1st edition (1977–1988) Tharizdun's existence was first revealed in the module The Forgotten Temple of Tharizdun (1982), by Gary Gygax. Tharizdun was subsequently detailed in the World of Greyhawk Fantasy Game Setting (1983).
