Beneath the Temple of Elemental Evil

The Temple of Elemental Evil is an adventure module for the fantasy role-playing game Dungeons & Dragons, set in the game's World of Greyhawk campaign setting. The module was published by TSR, Inc. in 1985 for the first edition Advanced Dungeons & Dragons rules. It was written by Gary Gygax and Frank Mentzer, and is an expansion of an earlier Gygax module, The Village of Hommlet (TSR, 1979). The Temple of Elemental Evil is also the title of a related 2001 Thomas M. Reid novel and an Atari computer game.
The Temple of Elemental Evil was ranked the 4th greatest Dungeons & Dragons adventure of all time by Dungeon magazine in 2004, on the 30th anniversary of the Dungeons & Dragons game.
In the module T1 The Village of Hommlet, the player characters must defeat the raiders operating out of a ruined fort nearby, and thereafter the characters can use Hommlet as a base for their adventures. The adventure begins in the eponymous village of Hommlet, situated near the site of a past battle against evil forces operating from the Temple. The adventurers travel through Hommlet and are drawn into a web of conspiracy and deception.
The module is intended for first-level characters, who begin the adventure "weary, weak, and practically void of money". They travel to a town with a reputation as having a great opportunity to earn fortunes and to defeat enemy creatures, but also to lose one's life. While the town initially appears hospitable, the characters soon learn that many of its inhabitants are powerful spies for minions of evil.
