Demogorgon (Dungeons & Dragons)

In the Dungeons & Dragons roleplaying game, Demogorgon is a powerful demon prince. He is known as the Prince of Demons, a self-proclaimed title he holds by virtue of his power and influence; which in turn, is a title acknowledged by both mortals and his fellow demons.

Description
Demogorgon appears as an eighteen-foot tall, reptilian (or amphibious) hermaphroditic tanar'ri with a somewhat humanoid form. Two baboon heads sprout from his twin snake-like necks, and his arms end in long tentacles. Demogorgon's two heads have individual personas, called Aameul and Hedradiah. They strive to dominate each other, but are unable to achieve control because they are aspects of one another. In the 3E sourcebook Book of Vile Darkness, he is erroneously depicted as having hyena heads instead of baboon heads. His title as Prince of Demons is contested and of somewhat inaccurate in that in the Chaos of the Abyss there are no official titles. He holds this title through power and the fact no other demon has been able to prove themselves his superior and wrest the name from him.

Demogorgon can hypnotize with a gaze or drive enemies insane. His whip-like tail has the ability to drain the life energy right out of a living foe. His tentacles cause living creatures to rot away, as if by some sort of rapid leprosy.

Realm
Demogorgon lives on the 88th layer of the Abyss, known as Abysm, the Brine Flats, or Gaping Maw. This is a layer consisting of a great sea of briny water broken by tall, sharp, ugly, rocky prominences rising out of the endless murky water into a sky of yellow mist. Demogorgon's palace is two twin towers shaped very roughly like tightly coiled serpents that are covered with sharp, ugly fin-like features and spines, and crowned at the top with skull-shaped minarets. The two towers are linked by a bridge near the top. Beneath the fortress are reefs and caverns where aboleths, kraken and ixitxachitl dwell, constantly warring with each other and worshipping Demogorgon in his palace above.

The only significant landmass of the layer is a vast continent covered in tropical jungles. Here, Demogorgon's capital city of Lemoriax is located.

Relationships
The hatred between Orcus and Demogorgon is legendary. He is also a dedicated foe of both Graz'zt and Fraz-Urb'luu. Some of his allies include the Succubus Queen Malcanthet; the currently imprisoned Shami-Amourae was his former consort. In Gary Gygax's Gord the Rogue series, he is the brother of another demon lord called "Mandrillagon."

Cult of Demogorgon
Demogorgon's cult is relatively small compared to "true" deities, but much larger than those of most fiends. He is worshipped not only by evil humans, but also by the intelligent rays known as ixitxachitl.

Demogorgon in Dragonlance
Demogorgon made an early appearance in the Dragonlance campaign setting in Dragon #85, in the short story "A Stone's Throw Away" by Roger E Moore. The story describes Tasselhoff Burrfoot foiling an evil wizard's attempt to summon the demon lord.

Demogorgon in Greyhawk
In the World of Greyhawk campaign setting, Demogorgon sometimes goes by the ancient name "Ahmon-Ibor," or "the Sibilant Beast." He is responsible for corrupting the paladin Sir Kargoth and transforming him and thirteen of his fellow Knight Protectors of the Great Kingdom into Oerth's first death knights.

Baldur's Gate
In the computer role-playing game Baldur's Gate II: Shadows of Amn, it is possible to make a sacrifice to Demogorgon, thus summoning some demons with no wish to be friendly. In the expansion pack Baldur's Gate II: Throne of Bhaal, an avatar of Demogorgon appears imprisoned in the dungeon known as Watcher's Keep. The player's standard quest is to seal the dungeon in order to keep Demogorgon imprisoned, but the player can also destroy Demogorgon's avatar, sending him back to the Abyss.

Standard players may find Demogorgon very difficult. Power gamers may find him varying from hard to disappointing, depending on whether they are playing using difficulty-enhancing mods, such as "Tactics" (these may make him stronger, but normally requires that the players be far more powerful just to reach him, making Demogorgon not quite as hard, but still more challenging than the original game), or 'Ascension', which restores Demogorgon to his 'original' difficulty, which was deemed too difficult for more casual players, resulting in his statistics and abilities being reduced.

Nethack
In the game Nethack, Demogorgon is probably the most difficult demon in the game, as he wields a fearsome combination of stunning, poisioning, and damage attacks not seen in other demons. However, he does not have a fixed place in the game, and is generally only seen when other major demons summon him (a small probability per turn). This means that he is relatively easy to avoid if the player is not deliberately baiting him.

Creative origins
Demogorgon is based on the pagan god or demon Demogorgon, which was invented by Christian scholars as a being whose very name is taboo. A creature name demogorgon is featured in John Milton's Paradise Lost, Lodovico Ariosto's Orlando Furioso, Spenser's Faerie Queene and Percy Bysshe Shelley's Prometheus Unbound, although the D&D Demogorgon, appearance and history-wise, is not based on any of those sources.
