-->''A sinister force, long thought destroyed, stirs from the black hole that spawned it. Like an ebony darkness it prowls the land and safety is but an illusion, for it watches from every shadow and ponders possibilities.''

A classic ''TabletopGame/DungeonsAndDragons'' TabletopRPG adventure module that was also adapted into a video game by Troika.

The {{Backstory}} tells of the TempleOfDoom dedicated to the Demon Queen of Fungi, Zuggtmoy (don't laugh, she's one ''mean'' [[TheManBehindTheMan hidden]] FinalBoss!). The forces of good [[SealedEvilInACan sealed and hid her inside her temple]] with the help of five powerful wizards. For many years the temple was quiet and the nearby village of Hommlet was prosperous, but there are signs of life in the temple yet...

The temple was divided into roughly five sections, one for each classical element and a fifth lowest for herself and her followers. A firm believer in [[SocialDarwinist Social Darwinism]], Zuggtmoy had the head priest of each upper level go through a near constant EnemyCivilWar to find out who was the strongest.

The Temple of Elemental Evil is part of the ''TabletopGame/{{Greyhawk}}'' setting.

In 2001, Wizards of the Coast published a novelization of the module, written by Thomas M. Reid, who also contributed to R.A. Salvatore's ''Literature/WarOfTheSpiderQueen'' novel series.

In 2002, a 3rd Edition revisit, fittingly titled ''Return to the Temple of Elemental Evil'' put a new temple inside of an extinct volcano, 25 years after the fall of the first temple, in in-game time. The new Temple was actually [[spoiler:an EvilPlan by [[EldritchAbomination Tharizdun]], god of Entropy, to escape his prison.]] This game in turn was remade as a [[GameMod fan module]] for ''VideoGame/NeverwinterNights2''.

A partial conversion of the original module for the 4th Edition rules, covering the first leg of the adventure in Hommlet, was distributed by Wizard of the Coast to RPGA members in 2009; of the rest, there has yet been no sign.

The 1985 tabletop version (pen, paper, and dice) has many of the tropes on the TabletopRPG and ''TabletopGame/DungeonsAndDragons'' pages. The video game has its own set of VideoGameTropes, see ''VideoGame/TheTempleOfElementalEvil''.
!!The tabletop game provides examples of following tropes:

* AchillesHeel: The Goldenskull (if destroyed) to Zuggtmoy.
* CoolSword: Fragarach and its twin Scather.
* DependingOnTheArtist: Between the various incarnations of the module and his appearances in other material such as the miniatures spin-off game, the only thing consistent about Lareth's appearance is his long hair. Armor, facial structure and sometimes even hair color vary greatly.
* DidYouJustPunchOutCthulhu: It's extremely difficult to do, but the module notes that the player characters conceivably ''could'' defeat Zuggtmoy in direct combat. If that happens, she'll be banished back to the Abyss like any other demon lord, but the Elemental Nodes will also be destroyed, the Golden Skull will be useless, and the Temple will have effectively been defeated once and for all.
* TheDragon: Hedrack, to the demigod Iuz.
* EverythingTryingToKillYou: Hoo boy. Just ''existing'' in the Elemental Nodes is enough to kill you by degrees... and that's if you manage to not run into the numerous dragons and other nasty creatures populating each node.
* FightingAShadow: Straight D&D case with Zuggtmoy. Reducing her HitPoints to zero isn't enough to permanently kill, but it does banish her to the Abyss for several decades, destroys the Elemental Nodes, makes the Golden Skull useless, and effectively ends the threat of the Temple once and for all. Destroy the Orb first, however, and then [[DeaderThanDead defeat her within 4 days....]]
** As is Iuz, but if you kill him, it causes him to spend a long enough time recovering that most of his followers leave him, weakening him further.
* HopelessBossFight: Hedrack may summon Iuz (or he may fail) in your battle with him, when you fight him...
** BigDamnHeroes: Then Saint Cuthbert takes him away (after they heal any damage he has done).
* TheMole
** Hommlet: traders Rannos Davl and Gremag
** Nulb: Otis, Mother Screng (Canoness Y'Day) and Hruda (Murfles)
** The Temple: Kella the druid, Smigmal and various monsters (jackalweres, a lamia and two werewolves)
* EnemyCivilWar: Encouraged by the fungus goddess between the elemental level priests.
* KillerGameMaster: This module would turn even Gandhi into one. Seriously. This module raises complaints, warranted and unwarranted, of TheGMIsACheatingBastard. Particularly when [[spoiler:the Temple's assassins start to come after you...]]. The module also included rules for replacement forces being recruited and actually explicitly said that the temple forces would increase by the same amounts if the {{PC}}s were not killing off monsters quickly enough. If the {{PC}}s spent a lot of time training, crafting or otherwise wasting time any non-unique enemies could be two or three times more numerous for instance fighting twelve trolls instead of the original four in the room. A creative GM would have no problem deciding the temple could go on the offensive when it's forces were sufficiently built up, completely changing the tone of the scenario from a standard, if well crafted, dungeon crawl to a desperate struggle to save Hommlet and Verbobonc from a massive onslaught.
-->GM: "After several weeks spent in Hommlet researching spells, training and crafting useful magic items for your assault on the temple, your peaceful interlude is interrupted by the panicked news from a farmer of a vast army of humanoids bearing the colours of the four temples sighted approaching the village..."
-->PC: "OhCrap...."
* NiceJobBreakingItHero: Jaroo Ashstaff decided only to have the top level of the temple cleared the first time.
** When Creator/GaryGygax ran this module for the first time with his original group, Rob Kuntz decided to run his character, Sir Robilar through the dungeons solo. He defeated the dungeon (a CrowningMomentOfAwesome in itself), but Gary, annoyed that Kuntz had run so rampant through the Temple, decided to bring down the long arm of the law to tear his castle down to its component bricks.
* NoCampaignForTheWicked: Averted, evil players can get to ally with Zuggtmoy or Iuz and spread evil, but only in the Troika video game adaptation.
* SavageSetpiece: the rats.
* TempleOfDoom: The titular Temple of Elemental Evil.
* TitleConfusion: Just about everyone (even this article) leave off the "The" at the start of the title. The smaller font for it kinda encourages it.
* TokenEvilTeammate: several.
* TotalPartyKill: A common occurrence in the Temple of Elemental Evil.
