History of the Demogorgon
Dungeons and Dragons
In the Dungeons and Dragons fantasy role-playing 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. Demogorgon was also named as one of the greatest villains in D & D history by the final print issue of Dragon. Demogorgon first appeared in the D & D game in Eldritch Wizardry in 1976, and he appeared in the original Monster Manual in 1977. Demogorgan is an 18-foot-tall reptilian (or amphibious) hermaphroditic tanar'ri with a somewhat humanoid form. He can charm enemies and hypnotize foes.
Stranger Things
The Demogorgon was a predatory humanoid creature that entered Hawkins, Indiana in November 1983. The creature originated from the parallel dimension known as the Upside Down. When Eleven, a psychic test subject from Hawkins National Laboratory, made inter-dimensional contact with it, a gate between dimensions opened at the lab. The creature passed through, terrorizing Hawkins for approximately a week. It abducted various residents and took them back to the Upside Down, usually killing them. The friends and family of Will Byers, one of the Demogorgon's victims, slowly began to uncover the truth about the creature, with the help of the escaped Eleven. The creature was finally defeated and destroyed by Eleven in a showdown at Hawkins Middle School.
Realm
The 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. His towers are said to extend so far beneath the sea that they connect to the layer beneath him where he speaks with the obyrith lord Dagon. Numerous isles dot the layer, but they all resemble Demogorgon's palace: twin rookeries rising straight out of the sea and into the sky. The only significant landmass of the layer is a vast jungle-covered continent. Here, Demogorgon's capital city of Lemoriax is located.
Relationships
His title as Prince of Demons is contested and somewhat misleading in that in the chaos of the Abyss there are no official titles and positions. He holds this title through sheer power and the fact no other demon has been able to prove themselves his superior and wrest the name from him. Demogorgon is also known as Lord of All That Swims in Darkness.
