Elements of the Cthulhu Mythos

The following tables and lists feature elements of the Cthulhu Mythos, that are often shared between works within that fictional setting.

The Cthulhu Mythos was originally created by writer H. P. Lovecraft in his horror short stories, although the term itself was coined later by August Derleth. Many writers, both during Lovecraft's lifetime and after, have added stories and elements to the Mythos. There is no central co-ordination of these stories, nor any oversight of the Cthulhu Mythos in general. Becoming part of the Mythos can be based on personal opinion and inclusion of these elements.

Overview

Tables appearing under these entries are organized as follows:

• Name. This is the commonly accepted name of the being or mythos element.
• Epithet(s), Other name(s). This field lists any epithets or alternate names. These are names sometimes mentioned in books of arcane literature, but may also be the names preferred by cults.
• Description. This entry briefly summarizes the being or mythos element.

Beings

Great Old Ones

Main article: Great Old One (includes a table listing all the Great Old Ones in the mythos)

The Great Old Ones are powerful, ancient creatures worshipped by deranged human cults. Many of them are made of an unearthly material with properties unlike normal matter. A Great Old One's influence is often limited to the planet where it dwells. If it is based on a planet outside the solar system, it can only extend its influence to Earth when the star of its planetary system is in the night sky. In such cases, the help of cultists performing various rituals may be required.

Outer Gods

Main article: Outer God (includes a table listing all the Outer Gods in the mythos)

The Outer Gods have unlimited influence, unlike the Great Old Ones, and function on a cosmic scale.[1] They include a subgroup known as the Lesser Outer Gods, or Other Gods.

Elder Gods

Main article: Elder God (Cthulhu Mythos) (includes a table listing all the Elder Gods in the mythos)

The Elder Gods oppose both the Outer Gods and the Great Old Ones. Many consider them to be non-Lovecraftian, because they introduce a good versus evil dichotomy into the cosmic indifference of Lovecraft's fiction.[2] However, others argue that these beings have no more concern for human notions of morality than the beings they oppose, and that humanity and the human world are beneath their regard.[3]

Great Ones

Main article: Dreamlands § Great Ones

The Great Ones are the so-called "gods" of the Dreamlands, but they are not as powerful as the Great Old Ones and are not even as intelligent as most humans. However, they are protected by the Outer Gods, especially Nyarlathotep.[4]

Other supernatural beings

Supernatural beings

Name	Epithet(s), Other name(s)	Description
Armandra	—	Daughter of the Great Old One Ithaqua. She resembles a beautiful redhead woman with webbed feet, whose membranes were cut down by surgeons, so now they look human but with square nail-less toes. She is a powerful sorceress, and one of the greatest acolytes of Ithaqua.
Beast of Averoigne	—	A seemingly supernatural-being, which is recorded as having descended upon the French principality of Averoigne, particularly both Vyones and Ximes, from an ominous red comet which appeared in the sky in 1369. It has no true body of its own, but needs to take possession of the body of another to feed, while transfiguring and horribly reshaping the host's body. Its resulting form is that of a pitch-black, semi-humanoid figure surrounded by a hellish nimbus of changing fiery-light, dimly revealing its shape. The limbs sway and writhe like boneless serpents, and grow sharp, harden claws. The neck similarly extends to a serpentine length and flexibility, whereas the head suddenly turns flat, reptilian, earless, and noseless.
Bgnghaa-Ythu-Yaddith	—	A gigantic Dhole worm tortured by the Denizens of Yaddith, in the Shrine of Nug, located within the Temple of Infra-Red Vapour on the Doomed Nebula Zlykariob (or Zlykrarlor, according to transcriptions).
Broodlings of Eihort	Gestalt Servants of the God of the Labyrinth	The Broodlings of Eihort are gestalt beings made up of the millions of tiny white spidery-brood of the Great Old One Eihort. A broodling looks like a deathly-pale, totally-hairless human.
Brown Jenkin	—	A mysterious rat-like creature, with a human-like face. The being was said to be the familiar of Keziah Mason. Probably a Rat Thing—see below.
Desh (Lesser and Greater)	—	Desh is the name given by Hyperboreans to creatures living within a near, but alternate dimension. Existing in many different forms, these creatures float through the invisible spaces around us, and are unaware of our presence as we are of theirs. Although the varieties of the Desh may be unlimited, only two forms are described (Lesser and Greater). Although of solid matter, they are semi-transparent, continually fading in and out of view.
Domaag T'eel	Servitor of the Great Old Ones	An alien-mass, made up of pseudopods, dwelling within the Moon, and capable to altering its orbital motion.
Droom-Avista	The Jester	True form not described, but likely a great demon to be invoked as a genie
The Dunwich Horror	Son of Yog-Sothoth, Bugg-Shaggog	An invisible egg-shaped monster of a gelatinous consistence, covered in tentacled suckers and "feet like hogsheads", with a mostly human face.
Father Dagon and Mother Hydra	—	Both appear as abnormally large Deep Ones.
Fthaggua	Lord of Ktynga	Appears as a bluish ball of energy. Fthaggua is both the lord and leader of the fire vampires, and dwells with them, and their god Cthugha, on or near the star Fomalhaut.
Fishers from Outside	—	The Fishers from Outside are much more avian in appearance than shantaks, though having one leg and a glaring Cyclopean eye and hideous, hooked, fang-lined beak. They are the servitors of the obscure Great Old One Groth-Golka, acting as proxies for their sire, by accepting both human sacrifices and worship by cultists. Fishers brood in caverns on the Moon, and are also sometimes connected with worship of the lunar Great Old One Mnomquah. Their sire is the hideous Quumyagga.
Fosterlings of the Old Ones	—	The Fosterlings of the Old Ones are the mutant offspring of matings between human females and Outer Gods or Great Old Ones. Through a special ritual, the Outer God or Great Old One sends a dream which reaches into the womb of a pregnant woman, altering the genetic structure of the unborn fetus. Once born, the child spends many years as a normal human being, until one day it transforms into something more closely resembling its alien parent.
The Four Horsemen of Nyarlathotep[5]	—	These characters feature in the comic series Fall of Cthulhu as servitors of Nyarlathotep and should thus be regarded as Million Favoured Ones. They are in order: Sysyphyx: "the Scourge of Atlantis". She is a multi-eyed worm that cuts off the head of her victims, replaces their spinal cord, and shapeshifts to look like them. She was (originally) a fat, cyanotic, red-headed woman who prophesied for Atlantis. Gnruk of Vol'Kunast: "Devourer of the Royal Corpse of Thuln", he is a disembodied essence that lies within an ancient box. When the box is opened alone, his essence enters into the body of the opener, and transforms them into a corpse-eating demon. The Masked Mute: "Sister of the Lost Abyss", she appears as a young, adolescent girl with innumerable masks to display her mood. Her true face can kill even the greatest monsters of the Dreamlands. Gith: "Father of Pestilence" and "Champion of Damnation". Gith is a mindless force from the Dreamlands, who can possess a human vessel (provided certain rites be taken, including removing the Vessel of its soul and disguising the Vessel as Anubis. Nyarlathotep states that Gith will only merge with a soulless child of the jackal.). He appears as a banded man (the Vessel's shape) with purple/blue flames in place of the eyes and mouth.
Fungus Vile	—	A kind of parasitic life form, neither really plant nor animal in nature, able to infect any organism it comes into contact with. It is suspected that this material originated on cold Yuggoth and subsequently spread through the cosmos with the mi-go.
Gnoph-Keh	—	Appears as a huge gnophkeh—possibly an avatar of Rhan-Tegoth or an independent entity.
Pth'thya-L'yt	—	A female Deep One, daughter of Mother Hydra who is almost 300,000 years old. For the last 80,000 years, she has lived in the city of Y'ha-nthlei, mating with Dagon, a union which many believe will result in the birth of a new species of Cthulhu's minions.
The High Priest Not to Be Described	—	Humanoid wearing a silken mask.
Knygathin Zhaum	—	Appears as a hairless, quasi-humanoid Voormi; Final form of no discernible species.
K'thun (female) and Noth-Yidik (male)	—	Abhorrent, malodorous beings whose mating spawned the Hounds of Tindalos.
The Lurker in the Star Pool	—	One of the Million Favored Ones of Nyarlathotep, possibly one of the Outer God's offspring. For aeons it has dwelled in the Star Pools, and today is in the servitude of the Floating Horror cult. Highly mobile, the Lurker has large membranous wings for flying and webbed appendages for swimming or walking on land. The creature's full appearance is confusing to behold, as it appears to be a mass of both multiple independent wriggling and squirming monstrosities.
Magnum Innominandum[6]	Great Not-to-Be-Named, The Nameless Mist, N'yog-Sothep, Milk of the Void	According to H. P. Lovecraft, this being is the spawn of Azathoth (making it on par with the Magnum Tenebrosum and Cxaxukluth) and is associated with, and possibly the progenitor of, Yog-Sothoth.[7] Little is known about this god, but it is considered to be extremely dangerous to sorcerers, hence its title "the unnameable" (archaic terminology, meaning not to be summoned or ritually named in an incantation.
Million Favored Ones	—	Beings said to be Nyarlathotep's spawn.
Mlandoth and Mril Thorion	The Source, The One	Unknown.
Mr. Shiny	—	Mr. Shiny (or Albert Shiny) is a shoggoth lord and an unusually intelligent and purposeful one, capable of controlling his body shape so as to pass for a human. Controlling his body in this manner requires continuous mental effort.
Narrathoth the Forgotten	—	A tall, whitish, and reptilian humanoid, larger than a man, with a single three-lobed eye. He is one of Cthulhu's servitor able to grant wishes like a djinn.
N'rath-Gol	Spawn of Nyarlathotep	One of the countless minions of Nyarlathotep—likely a Million Favoured Ones—who dwells on the dark planet K'yi-Lih, embodying the Chaos.
Our Ladies of Sorrow	—	Our Ladies of Sorrow-or the Three Mothers-are three powerful entities, and three of Nyarlathotep's Million Favoured Ones. They are: Mater Lachrymarum ("Our Lady of Tears"), the eldest, followed by Mater Suspiriorum ("Our Lady of Sighs") and finally the youngest Mater Tenebrarum ("Our Lady of Darkness"). They have inspired many legends, including that of the triple goddess, the fates, the gorgons, and Shakespeare's three weird sister-daughters of darkness (witches).
Pharol the Black	—	Appears as a black, fanged demon with tentacles instead of arms.
The Shaping Tree	—	A hideous tree-like horror with branches like rat's tails and weird pustules. It is able to transform human victims into jelly amorphous vectors of strange broodlings. The Shaping Tree is located in Australia, and is likely related to Shub-Niggurath.
Sho-Gath	The God-in-the Box	A smoky entity with the travesty of a human face, entrapped into a box.
Sss'haa	—	Leader of the serpent people of Valusia.
Ubb	Father of Worms	Leader of the planarian-like Yuggs. He is a large, aquatic, chthonian-like entity, pale gray and slug-like with a large mouth full of horn-like teeth, and ringed with tentacles. Ubb dwells in the cold fastness of the Pacific Ocean, with the rest of his race. The yuggs are said to guard their god, the Great Old One Zoth-Ommog, whose tomb, legend tells, lies at the bottom of an abyssal trench near the island of Ponape.
Ugga-Naach	Abomination of the Ancients	The result of an abominable mating between Nyarlathotep (in a tentacled avatar) and a “surrogate” human mother. Once born, it manifests as a 1.5 meters tall homunculus, slender and tanned in appearance, with a crimson tentacle in place of head, a glossy tongue, and green sharp-teeth.
The Five Vaeyen	—	Quintet of vulture-like statues that both guard and sequester the Great Old One Cyäegha
Wilbur Whateley	—	Mostly human twin of the aforementioned Dunwich Horror.
The Worm That Walks	The Putrefied Horror	A loathsome being, looking like a human corpse decayed into tones of green, black, and blue, with dripping pieces of flesh hanging from it. Prodigious claws or talons dangle from this apparition's fingers, and from the undead monster's eye sockets stare lidless, ban, eyeballs.
Wuthoqquan's Bane	—	A large, shapeless beast lurking in the sewers of Commoriom.
Xathagorra	The Chaos Spawn	Vile, multiform creature with a vast wingspan.
Xexanoth	Bane of Aforgomon	Unknown.
