Demogorgon Demogorgon , also known as the Prince of Demons , was a powerful demon lord and lesser deity . The self - proclaimed title " Prince of Demons " was won by virtue of power and influence ; many demons challenged it but none could defeat Demogorgon and claim it . Description . The demon towered a full eighteen feet in height , his body at once sinuous like that of a snake and powerful like that of a great ape . Two baleful baboon heads ( with blue and red faces ) leered from atop his lumbering shoulders , from which writhed two long tentacles . His lower torso was saurian , like some great reptile with blue - green , scaly skin . He had an immense forked tail . Personality . Each of Demogorgon ' s head had its own name and personality . One was named Aameul while the other was named Hethradiah . The two heads warred with each other . Aameul relished deception , while Hethradiah relished destruction . Combat . Demogorgon preferred to avoid direct conflict , instead using magic to help his servants . Demogorgon could hypnotize with a gaze or drive creatures around him to terror and insanity just at the sight of him . His whip - like tail had the ability to drain the life energy right out of a living foe . His tentacles caused living creatures to rot away , as if by some sort of rapid leprosy . He was extremely resistant to magic . Demogorgon was comfortable underwater . Realm . Demogorgon lived on the 88th layer of the Abyss , known as the Gaping Maw . This was a layer consisting of a great sea of briny water broken by tall , sharp , ugly , rocky promontories . Demogorgon ' s palace , called Abysm , consisted of two twin towers roughly shaped like tightly coiled serpents , crowned at the top with skull - shaped minarets . The two towers were linked by a bridge near the top . Most of the fortress lay underwater beneath the towers . The reefs and caverns near the fortress were home to aboleth , kraken , and ixitxachitl s , which constantly warred with each other and worshiped Demogorgon in his palace above . Demogorgon also kept a fortress in the bog of the Gaping Maw called Ungorth Reddik . This was where he housed his armies of hezrou s , aboleths , scrag s , skum , and ichythoid creatures . The fortress was guarded by unusual retriever s , golem s , and other evil construct s . The only significant landmass of the layer was a vast continent covered in tropical jungles . Here , Demogorgon ' s capital city of Lemoriax was located . Demogorgon was also served by abyssal marauder s . Cult of Demogorgon . Demogorgon ' s cult was relatively small compared to " true " deities , but much larger than those of most fiends . He was worshiped by the intelligent manta ray race known as ixitxachitl s . Demogorgon ' s other worshipers included troglodyte s , kuo - toa , and other humanoid s , particularly evil human s . His cult prospered in times of chaos and caused great destruction wherever it was found . Temples to Demogorgon were split in half , with one side representing Aameul and the other representing Hethradiah . Demogorgon ' s domains were Chaos , Corruption , Demonic , and Evil . His symbol was that of a forked tail , often wrapped around a skull or sword . Aspects of Demogorgon . Mortals could not summon Demogorgon himself , but the most pious could use sacrifice to summon a temporary aspect of Demogorgon . The aspect was smaller and not as powerful as Demogorgon . An aspect of Demogorgon was always unbalanced , taking after one head more than the other . Relationships . The hatred between Orcus and Demogorgon was legendary . He was also a dedicated foe of Graz ' zt , and Fraz - Urb ' luu . He hated Sekolah and encouraged his followers to kill sahuagin . Demogorgon was allied with the obyrith lord Dagon , who often advised the heads of Aameul and Hethradiah separately . Dagon provided intellect , while Demogorgon provided brute strength . Some of his other allies included the Succubus Queen Malcanthet . The imprisoned Shami - Amourae was his former consort . He was the brother of another demon lord called Mandrillagon . History . Demogorgon once had a single head until a blow from Amoth split it in two . Soon after that battle , Demogorgon defeated the stone primordial Storralk . He kept Storralk beneath his throne , torturing him for eternity . On Nightal 15 , 1486 DR , Archmage Gromph Baenre weakened the barriers of " faerzress " , inadvertently " summoning " Demogorgon and allowing him to pass from the Abyss to the Prime Material Plane . He arrived at the tower of Sorcere in Menzoberranzan and cut a swath of destruction as he exited the cavern . Gromph was able to weaken the " faerzress " because of his study of psionics and the psychic conveyance of a plan devised by the goddess Lolth . In 1487 DR , Drizzt defeated Demogorgon in Menzoberranzan being a conduit from a barrage of magic and energy , released upon him and held by the kinetic barrier of an illithid hive - mind .
