Great Ones
The so-called "gods" of the Dreamlands, the Great Ones 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, particularly Nyarlathotep. While they once lived on peaks across the world they were driven off of lower mountains by the spread of humanity until they had to leave Earth entirely, leaving only a mark on Mount Ngranek. The Great Ones now rule from their hidden fortress of Kadath, whose location in time and space is unknown. As well as occasionally returning to white capped Thurai, Lerion and Hatheg-Kla on cloud ships under the cover of a light mist, they abandoned Kadath for a brief period for the "sunset city" that Randolph Carter conjured in his dreams. In the past, the Great Ones often married human women, so many human inhabitants of the Dreamlands have Great One blood in them.
Dagon- A deity worshipped by the Deep Ones. It is an evil fish-like god.
Hagarg Ryonis- Hagarg Ryonis, also known as The Lier-in-Wait is one of the Great Ones, the gods of Earth that reside in Kadath. He appears as a huge reptilian monster. (HP Lovecraft's Dreamlands, "Wizards of Hyperborea")
Karakal- AKA Karakal of Flames is one of the Great Ones, the gods of Earth that reside in Kadath. He might also be the same being as Zo-Kalar. (HP Lovecraft's Dreamlands, "Wizards of Hyperborea", Mike Minnis' "The Crawler of Pnoth")
Lobon- Lobon, also known as Lobon of the Sacred Spear is one of the Great Ones, the gods of Earth that reside in Kadath. He appears as an ivy-crowned youth bearing a spear. ("The Doom That Came to Sarnath"; H.P. Lovecraft's Dreamlands, John Fultz's "Wizards of Hyperborea")
Nath-Horthath- Nat-Horthath is known as one of the chief gods of Celephaïs. ("Celephaïs", The Dream-Quest of Unknown Kadath; HP Lovecraft's Dreamlands, "Kadath/The Vision and the Journey")
Oukranos- Oukranos is one of the Great Ones, the gods of Earth that reside in Kadath. (The Dream-Quest of Unknown Kadath)

Zo-Kalar- Zo-Kalar is a Great One dwelling on Kadath. Zo-Kalar was one of the chief gods worshipped in doomed Sarnath along with Tamash and Lobon. (HPL: "The Doom That Came to Sarnath"). It is also possibly the same being as Karakal or Karakal of Flames. ("The Doom That Came to Sarnath"; "Wizards of Hyperborea")
Outer Gods and Lesser Outer Gods
As it is known in the Mythos, the Outer Gods are ruled by Azathoth, the "Blind Idiot God", who holds court at the center of infinity. A group of Outer Gods dance rhythmically around Azathoth, in cadence to the piping of a demonic flute. Among the Outer Gods present at Azathoth's court are the entities called "Ultimate Gods" in The Dream-Quest of Unknown Kadath (called "Lesser Outer Gods" in the Call of Cthulhu RPG), and possibly Shub-Niggurath, the "Black Goat of the Woods with a Thousand Young". Yog-Sothoth, the "All-in-One and One-in-All", co-rules with Azathoth and exists as the incarnation of time in the cosmos, yet is somehow locked outside the mundane universe. Nyarlathotep, the "Crawling Chaos", is the avatar of the Outer Gods, existing as the incarnation of space and functions as an intermediary between the deities of the pantheon and their cults. The only Outer God to have a true personality, Nyarlathotep, possesses a malign intellect and reveals a mocking contempt for his master's degree. Lovecraft himself never made reference to them as the Outer Gods, instead calling them the Other Gods or the gods of the outer hells, as noted in his short story "The Other Gods".
Abhoth- Referred to as “The Source of Uncleanliness” it is a dark gray mass found in the cavern of Y’quaa beneath Mount Voormithadreth.
Aiueb Gnshal- (The Eyes Between Worlds, The Child-Minded God) is a mysterious Outer God, who has his abode in a forgotten temple located somewhere in Bhutan. He appears as a formless black void, with seven pulsing orb-like eyes, and is mainly worshiped by ghouls.
Aletheia- Aletheia (The End of the Darkness) is a god-like entity symbolizing or incarnating the truth. Named after the Greek goddess of truth, it manifests as a vast spiral of manifold titanic hands with a single cycloptic eye in each palm as in the Hamsa, and kilometric wire-like protrusions able to ensnare living beings, replacing their spinal bone in puppet-like fashion.
Azathoth- Sometimes referred to as the "Blind Idiot God", is a dreaming monster who rules the Outer Gods and created them, along with many other worlds. Azathoth can't understand anything in his dream, hence his title. Azathoth also shifts in his slumber, causing reality to change.
Azhorra-Tha- An Outer God imprisoned on the planet Mars, as it fled from Earth after the imprisonment of the Great Old Ones. Its appearance is that of an insectoid to toad-like squid, but its shape continuously changes, emitting an awful buzz. The Mi-Go discovered the prison of Azhorra-Tha the millennia after, and made everything to not reveal its location to any human being.
The Blackness from the Stars- The Blackness from the Stars is an immobile blob of living, sentient darkness, torn from the primal fabric of the cosmos at the center of the universe. It is distinguishable in darkness only as vaguely shimmering oily pitch. Although intelligent, it speaks no known language and ignores attempts to communicate.
The Cloud-Thing- A man-eating cloudy mass, it is an unnamed Outer God at the court of Azathoth.
C'thalpa- A huge mass of living sentient magma, located in the Earth's mantle. She is mother of the Great Old One Shterot, and five other unnamed hideous children. She is also served by a race of mole-like humanoid burrowers known as the Talpeurs.
Cxaxukluth- (Androgynous Offspring of Azathoth) is one of the Seed-Spawn of Azathoth, grown to adulthood and monstrous proportions. In appearance, Cxaxukluth resembles something of a cross between Azathoth and Ubbo-Sathla: an amorphous, writhing mass of bubbling, nuclear, protoplasmic-gel. He normally dwells alone within an unnamed dimension beyond time and space, unless disturbed or summoned away.
Daoloth- “The Render of the Veils or The Parter of the Veils” is described as a being that dwells in dimensions beyond the three known to humans.
Darkness- Darkness (Magnum Tenebrosum, The Unnamed Darkness) is a mysterious entity spawned by Azathoth, and is the progenitor of Shub-Niggurath.
D’endrrah- (The Divinity) is a sort of blurry female entity of supernatural beauty, dwelling within her obsidian palace located on Mars' moon Deimos. She lives in a hall composed of myriad mirrors that distort her appearance, which is that of a tentacled dark abyss. This Mythos entity is somewhat inspired by C. L. Moore's Shambleau, the illusionary Martian she-vampires of lust.
Kaajh'Kaalbh A lesser Outer God, servitor of Azathoth, but secluded in a parallel chaotic-dimension where everything is unstable. The god itself is constantly formed or disrupted and has no true form at all. Whoever attempts summoning this entity needs the aid of a dimensional shambler, and the deity may manifest in a variety of forms, often as an immense lava lake or a vast pool of solidified quicksilver.
Laldagorth- (The Dark Devourer) is both the cousin and servant of Azathoth, appearing as a black, shapeless, malevolent mist. The sight of such a fiend is unsettling if not traumatizing.
Lu-Kthu- (Birth-womb of the Great Old Ones or Lew-Kthew) is a titanic, planet-sized mass of entrails and internal organs. On closer examination it appears a wet, warty globe, covered with countless ovoid pustules and spider-webbed with a network of long, narrow tunnels. Each pustule bears the larva of a Great Old One.
Mh'ithrha- An invisible wolf-like fiend similar to Fenrir of Norse mythology (if not coincident). Mh'ithrha (Arch-Lord of Tindalos) is the lord of the Hounds of Tindalos, and the most powerful. Although not an actual Outer God as such, its form and astounding powers defy standard classification. Mh'ithra's eternal battle with Yog-Sothoth is said to be legendary.
Mlandoth and Mril Thorion- Mlandoth and Mril Thorion are the Cosmic entities embodying Good and Evil in their purest and most basic form.
Magnum Tenebrosum- (The Unnamed Darkness) Presumably a vast, dark shape.

Ngyr-Khorath- A misty, incorporeal being with an "eye of flame" at its centre.
The Nameless Mist- The Nameless Mist (Magnum Innominandum, Nyog' Sothep) is a "misty, shapeless thing" spawned by Azathoth, and is the progenitor of Yog-Sothoth.
Nyarlathotep- A shape shifting Outer God and messenger of the Great Old Ones.
Nyctelios- Once an Elder God, Nyctelios has been punished by his peers—especially Nodens—for having created a race of foul servitors. He has been permanently banished from the Elder Gods' Olympus and imprisoned beneath the eastern Mediterranean Sea, near Greece, in a dark, basalt-built citadel named Atheron. However the exiled deity is not dead but just sleeping, and one day he will rise again from his abyss manifesting himself as a blue, 6-metre tall, Cyclops-like monstrosity, with the bulk of his body covered entirely in crawling worms.
Ny-Rakath- A goat-like fiendish horror with bat wings and multiple horns, mentioned as the brother of Shub-Niggurath.
Olkoth- Olkoth (God of the Celestial Arcs) appears as a demoniacal god-like entity able to reincarnate in human bodies if the stars are right (sort of a "Cthulhian" Antichrist). Olkoth may emerge in our dimension through an eyeless, grotesque statue of the Virgin Mary.
Shabbith-Ka- Appears as a shapeless, roughly man-sized purplish aura, spitting and crackling with powerful electrical arcs. A sense of power, malignancy, and intelligence accompanies it and persons able to gaze at its form long enough can see a rudimentary face or faces within the glowing mass.
Shub-Niggurath- Called The Black Goat of the Woods with a Thousand Young, is an Outer God.
Star Mother- The Star Mother, also called The Great Mother Of All", appears as a chunk of yellow-green stone about the size of an infant. Its shape suggests a plump, huge-breasted, faceless female figure. From it extend dozens of pencil-thin root-like strands. It is one of the Larvae of the Other Gods and has no cult, although served by zombie slaves.
Suc'Naath- Suc'Naath is one of the mindless gods which twist and dance in the court of Azathoth. It appears as a formless spinning hurricane-like thing with strings of violet and golden colors across its shape, constantly emitting sickening smacking and screeching noises while showing pain-stricken faces across its body.
Tru'nembra- (The Flautist of Azathoth) Composed of living sound. This being appears as a mass of shimmering air that constantly emits sound ranging from 60 Db to 150 Db.

Yog-Sothoth- An Outer God and cosmic entity born of the Nameless Mist.
Elder Gods
In post-Lovecraft stories, the Elder Gods oppose the likes of Cthulhu. Derleth attempted to retroactively group the benevolent deity Nodens in this category (who acts as deus ex machina for the protagonists in both The Dream-Quest of Unknown Kadath and "The Strange High House in the Mist"). Joseph S. Pulver mentions in his Nightmare's Disciple (2006) a set of original Elder Gods, but offers no descriptions of their true forms. The story introduces entities as Adaedu, Alithlai-Tyy, Dveahtehs, Eyroix, Ovytonv, Urthuvn, Xislanyx and Xuthyos-Sihb’Bz'. Others have a cult title as Othkkartho (Sire of the Four Titans of Balance and Order), which is said to be Nodens's son, and Zehirete, who is The Pure and Holy Womb of Light. Sk'tai and Eppirfon are both siblings. Eppirfon was originally Cthulhu's second bride who bore him a son, T'ith, now dead, murdered by Cthulhu himself.

Nodens- Nodens ("Lord of the Great Abyss") appears as a human male riding a huge seashell pulled by legendary beasts. In CthulhuTech supplements, Nodens is said to be the avatar of the Forgotten One Savty'ya.
Oryx- (The Bright Flame) is an Elder God that manifests as a giant pillar of blinding white and purple flames. Although its expression is bright and blinding, no one feels its heat. No one can look at Orryx more than a few seconds; after the first glance, the eyes of anyone who looks become sore and watery.
Oztalun- (Golden and Shimmering One) is an Elder God introduced by James Ambuehl. It is symbolized by a seven-pointed star symbol, which is his own Seal.
Paighon- The following is another Elder God with no description: Walter C. DeBill, Jr.'s Paighon, an extra-galactic entity which now dwells in Earth's core, said to be inimical to the Outer God Ngyr-Korath and his servitor 'Ymnar.
Shavalyoth- (Shadowy and Shapeless One) is an Elder God introduced by James Ambuehl, supposed to be dark and formless.

Dunwich Horror- AKA Yog Whateley, was the twin of Wilbur Whateley. Yog was the son of Yog-Sothoth and whose mother was a deformed albino human, Lavinia Whateley.
Elder Things- Elder Things are sapient, radially symmetrical, and nearly invincible. They are incredibly strange creatures, sharing characteristics of animals and vegetables alike. They are able to enter a peculiar state of preservation that allows them to survive extreme temperature fluctuations, vacuum, and without any need to eat or breathe. They have five sides of their body, being shaped like a tall, narrow hexagon, along with five eyes, five tendrils, five mouths, etc.
Ghast- Humanoid creatures that live in the vaults of Zin. They have no noses or ears but with kangaroo-like legs.

Half-Lovecraftian- Many (if not all) Lovecraftian Entities can shift into a human form, and will sometimes mate with human beings. The spawn of these unholy unions are known by most as "Half-Lovecraftian", as their true name is in Lovecraftian, making it impossible for most non-lovecraftian beings to know the true name. They include: Deep-one/humans (The Innsmouth People), and Wilbur Whateley (deceased son of Yog-Sothoth). Half-Lovecraftians have immense mental power, and in some cases, physical power, and many are zealots to the cause of their Lovecraftian parents (or the cause of the being that parent served).
Mi-go- An alien that looks like a cross between a fungus and a lobster but with wings.
Night-gaunts- A creature that inhabits Earth’s dreamlands. They have long tails, closed feet, horns and wings.

Spiders of Leng- AKA Leng Spiders are sentient cannibalistic creatures.
Spawn- Spawn are beings of horror, Eldritch and horrifying. They are literally born from nothing but the sheer will of a Lovecraftian God. While the term "Star Spawn" is normally used to define the Spawn of Cthulhu, the term can also be used for all things that serve Lovecraftian Gods, be it a Shoggoth or some other, unknown, Spawn.
Star Spawn- Resembling miniature versions of their lord, Star Spawn are the most common and well known of the Spawn. They reside either in the oceans (mostly the Antarctic or Indian), and they posses immense regenerative powers, able to re-grow lost limbs in seconds.
Shoggoth- Formless eye-covered blobs created by the Elder Ones as slaves.
Wilbur Whateley- Twin brother of the Dunwich Horror and son of Yog-Sothoth. He has a general humanoid and goatish appearance.
Horrors
Horrors are beings of amazing and awful power, beings that explore the cosmos, looking for or giving the truth to younger and less intelligent species (e.g. Humans), or simply to slaughter the poor beings and consume their home planet, using the dead husk for purposes unknown.
The term "horror" is used to explain any non-spawn, non-godly being that is still considered Eldritch, such as the Elaagoth. The term "Plague of Horror" is used to describe any gathering of these beings, be it an army or a mating season group.
