Cthulhu Mythos deities

Writer H. P. Lovecraft created a number of fictional deities throughout the course of his literary career, including the "Great Old Ones" and the "Outer Gods", with sporadic references to other miscellaneous deities (e.g. Nodens). The Elder Gods are a later creation of writers such as August Derleth, credited with formalizing the Cthulhu Mythos.

An ongoing theme in Lovecraft's work is the complete irrelevance of mankind in the face of the cosmic horrors that apparently exist in the universe, with Lovecraft constantly referring to the "Great Old Ones": a loose pantheon of ancient, powerful deities from space who once ruled the Earth and who have since fallen into a deathlike sleep.

Lovecraft named several of these deities, including Cthulhu, Ghatanothoa, and Yig. With a few exceptions, Cthulhu, Ghatanothoa, et al., this loose pantheon apparently exists 'outside' of normal space-time. Though worshipped by deranged human (and inhuman) cults, these beings are generally imprisoned or restricted in their ability to interact with most people (beneath the sea, inside the Earth, in other dimensions, and so on), at least until the hapless protagonist is unwittingly exposed to them. Lovecraft visited this premise in many of his stories, notably his 1928 short story, The Call of Cthulhu, with reference to the eponymous creature. However, it was Derleth who applied the notion to all of the Great Old Ones. The majority of these have physical forms that the human mind is incapable of processing; simply viewing them renders the viewer incurably insane.

This table is organized as follows:

In Joseph S. Pulver's novel Nightmare's Disciple several new Great Old Ones and Elder Gods are named. The novel mentions D'numl Cthulhu's female cousin, T'ith and Xu'bea, The Teeth of the Dark Plains of Mwaalba. Miivls and Vn'Vulot, are said to have fought each other in southern Gondwanaland during the Cretaceous period, whereas Rynvyk, regarded as one of the mates of Cthulhu's sister Kassogtha, likely matches with Cthulhu itself or a similar entity. Kassogtha would have sired Rynvyk three sons (one named Ult) and now rests in a crimson pool in the Hall of Tyryar (likely another name or dimension of R'lyeh), whose portal is located somewhere in Norway.
