Yog-Sothoth knows the gate. Yog-Sothoth is the gate. Yog-Sothoth is the key and guardian of the gate. Past, present, future, all are one in Yog-Sothoth. He knows where the Old Ones broke through of old, and where They shall break through again. He knows where They have trod earth's fields, and where They still tread them, and why no one can behold Them as They tread.

Yog-Sothoth to a human.

Yog-Sothoth is an Outer God and the embodiment of time and space across an essentially infinite number of space-time continuums, allowing him to be connected to the multiverse itself.


He was born from the Nameless Mist, one of the offspring of Azathoth alongside the Darkness and Nyarlathotep. He is also the progenitor of Cthulhu, Hastur the Unspeakable and the ancestor of the Voormi. He is also the father of Wilbur Whateley.

He was formed from the energy of Azathoth, in order to battle both God and Khaos, and is the second-in-command of the eldritch Lovecraftian pantheon only behind Cxaxukluth and the rarely seen Azathoth. He is the Gate, and the Key. The Outer God Yog-Sothoth like Azathoth completely uncaring about what humans do.

He is an unfathomably powerful deity and one of the most powerful of the Outer Gods, a race of ancient deities who wield great power, size and intelligence, as well as the largest and most intelligent—dwarfing the famous Cthulhu in the same scale that Cthulhu dwarfs humanity, and is a truly cosmic menace that is beyond mortal comprehension. Yog-Sothoth is the embodiment of all of time and space across an essentially infinite number of space-time continuums. For all intents and purpose, he is connected to the multiverse. He is the grandfather of Cthulhu and the grandson of Azathoth.

Like many Lovecraftian deities, Yog-Sothoth has a number of avatars and even followers (such as the Chorazos Cult) by which to expand his influence.

It is an entity of vast knowledge and power, and those who treat with it may learn much; any who do so must be wary, however: as with many of the creatures of the beyond, the mere sight of Yog-Sothoth's full form is sufficient to drive the mortal mind over the edge of insanity.

Relation to humans

Some witches and other practicians of magic use the name Yog-Sothoth in their incantations, usually for the purpose of necromancy. This is a dangerous task, since due Yog-Sothoth's incomprehensible power and nature, can turn any man insane.

The deity is also known to contact human's, giving them magical powers, usually for the goal of spreading his influence, and eventually releasing him.

Some notable human's who worship Yog-Sothoth are:

  • Abdul Alhazred: A sorcerer from 8th century Damascus, who wrote the Necronomicon, a book filled with knowledge of the Great Old Ones.
  • Joseph Curwen: A sorcerer from 17th century Massachusetts, who managed to get magical powers from the deity for his necromancy and life-extension.
  • Grigori Rasputin: A Russian mystic who became a follower of Yog-Sothoth during the 19th Century, and was given immortality by deity after his attempted assassination in 1916. In 1944 Rasputin got one step closer to releasing his master through Projekt Ragnarok, which released the demon who bore the Right Hand of Doom from Hell.


Yog-Sothoth, like the other Outer Gods, is unable to manifest in the physical plane, it must rely on a series of avatars to do its bidding. Some of these are included below.

  • Aforgomon: A Time Master, the aspect of Yog-Sothoth who keeps the flow of time.H e was revered by many cultures past, present, and future as the God of Time because of his preternatural ability to manipulate time and space. Little is known of this being's appearance because he only reveals himself to those who have angered him. However, it is known that he is accompanied by a blinding light. He is the mortal enemy of Xexanoth.
  • Umr at-Tawil: An amiable avatar who guards the Gate of Truth. Known as The [Most Ancient and] Prolonged of Life), also spelled Tawil At-U'mr or Tawil-at'Umr, he presides over the timeless halls beyond the Gate of the Silver Key and the strange, near-omnipotent Ancient Ones that dwell there. He is described as the silhouette of a man behind a strange, shimmering veil. He is one of very few apparently benign Lovecraftian Great Old Ones who does not cause insanity in those who view him and is one of Yog-Sothoth's more benevolent avatars.
  • Sut-Typhon: Also known as Sut-Thoth, a fake guardian angel that became the partner and host for Abigail Williams.
  • The Eater of Souls: An avatar of Yog-Sothoth worshiped by the Lloigor, this facet is believed to devour some kind of life-force from living beings, a substance that the Lloigor needed for an unstated purpose.


Like many Lovecraftian gods, Yog-Sothoth has many different appearances throughout the history of the mythos, by various authors. However, there seems to be a common agreement that Yog-Sothoth visually manifests as a mass of glowing orbs, with eyes or tendrils in some versions, and in others simply the orbs.

Like its brethren and children, Yog-Sothoth is thoroughly indescribable and unconceivable, way beyond human comprehension, and those in its presence can only perceive an approximation. it was described in many different ways throughout the various legends. However, there seems to be a common agreement that Yog-Sothoth visually manifests as a mass of glowing orbs that continuously merge, regrow and break apart, with eyes or tendrils in some versions. This shows that despite its locking, Yog-Sothoth is capable of communicating to some extend beyond the "No Space", demonstrating a form of omnipresence as well.

Sometimes, he looks like a huge mass of yellow tendrils and in Beyond the Gates of the Silver Key, he is shown as a large creature with eyes and tendrils. Whatever the case, Yog-Sothoth is among the most eldritch and incomprehensible of even Lovecraftian deities; far surpassing any and all of the Great Old Ones and even other Outer Gods, only matched in sheer power by fellow supreme Outer Gods like Azathoth.


He is an amoral entity who is simply beyond our understanding of petty morality or sanity.

Power and Abilities

Yog-Sothoth is among the most powerful beings in existence capable of rivaling Calur and Chronos, with its power being almost equal to that of its creator. It is a limitless cosmic being that is connected with all of space and time yet is locked away from mainstream reality. This monstrous deity sees all and knows all and can impart knowledge to anyone foolish enough to seek its favor, which often required human sacrifice or worse and would ultimately bring calamity and ruin to the would-be-follower.

Being the Outer God of time and space, Yog-Sothoth has control over all of space and time. Yog-Sothoth is himself all of the spacetime continuum and is omnipresent. Likely Yog-Sothoth's defining trait is his omniscience; Yog-Sothoth sees all, knows all, and is all, and possesses the vast sapience that not even his grandfather can lay claim to. Every being that possesses intelligence is considered a mere facet of Yog-Sothoth, from a mere human to the most complex Outer God. He has also shown to be able to bestow this omniscience to those he deems worthy, such as Randolph Carter.

He is, by all technicalities, indestructible and immortal for it is implied that nothing short of Azathoth waking up could truly get rid of him. He exists outside of the multiverse in an omni-lock. The entity is so powerful that merely seeing it or learning too much about its existence would drive one insane and create disaster. He is considered to be absolutely boundless from the perspectives of almost all beings, but is in truth implicitly restricted by Azathoth. Regardless, Yog-Sothoth is considered to be of equal importance to Azathoth as numerous individuals seek to release him in order to unleash the Old Ones from their prison


Yog-Sothoth was created by the Nameless Mist using the energy of Azathoth, who created all Outer Gods and Great Old Ones in order to battle both God and Khaos. Azathoth and the other Old Ones were eventually trapped in the Outerverse.

Yog-Sothoth is said to be the first Outer God that was created due to the fact that it embodies the universe molded by Azathoth and born from the Nameless Mist. And when God witnessed the sort of horrendous and terrible creations that Azathoth and his children are capable of constructing, He waged war against the eternal darkness. After the defeat of Azathoth, Yog-Sothoth was imprisoned by God in a what is said to be omni-lock, meaning that it is completely locked away from the current mainstream reality and among other realities, with it being its own reality that inhabits an existence which is not connected to any of the branches of creation and defines both human and inhuman conceptual equations made by the clashing between God, Khaos and Azathoth.

Yog-Sothoth had assisted the Great Old Ones as the military strategist, who became similar to the Time Lords in a previous universe. Arriving to the Doctor's Universe Yog-Sothoth discovered that it was free and had regained its god-like powers and decided to play out the various gambits and games it had only been able to simulate before. Over the millennia, it mounted millions of campaigns against inhabited planets using conquered races to bolster its forces.

He has first caused trouble for The Doctor in his second and Eleventh incarnations. It is rumored that he died while spreading himself across the Doctor's time-stream, but it has been proven false. He may or may not have tried to kill the Eighth Doctor by drinking him to death while the latter was under a Chameleon Arch.


Yog-Sothoth, alongside most other Outer Gods, are currently trapped in the Outerverse by God Himself, from which they can only be released with the Right Hand of Doom, the mysterious key to that dimension.

The key ended up in Hell at some point, where it was held by Mammon, the Prince of Hell of who represented Greed. At some point Mammon and Astaroth grafted the key onto a young cambion named Anung un Rama, who would be the only who can truly unleash the ancient deity into the universe. This cambion was later summoned to Earth by Projekt Ragnarok, the final project of the Ahnenerbe, which was led by Grigori Rasputin.

The demons secretly hope that Yog-Sothoth and the other Outer Gods could help them avoid their fate in the Lake of Fire, though whether this is would actually happen is not known, as the ancient deities would likely barley even notice them.

Even when trapped, Yog-Sothoth was able to have many children like Wilbur Whatley and Master Therion.

Beyond the Gates of the Silver Key

Charles Randolph Carter actually meets him, The Gate, the Key, and the Guardian. The encounter makes it very clear that it is the point of view which defines the nature of the interaction; there is nothing inherently evil or frightening about him. He opens the gates of the Multiverse to anyone who is willing to glimpse it and unlike the "nameless devourers" he is not going to harm you or force you into what you do not want. He gives Carter the option of leaving or going forward; The price is to see the true or at least partial vastness of what is, a flood of knowledge that overwhelms the current "self". Once Carter is at the nexus of all he is, was and will be, he is distilled into one being: a Wizard in a planet engaged in a battle; yet all Carter wants is to go back to Earth. How limited are we truly, and what does it take to move on beyond?

At the Mountains of Madness

William Dyer​ and Danforth, after escaping a Shoggoth, leave the Mountains on their plane. Danforth looks back and sees something that causes him to go insane. He refuses to tell anyone (even Dyer) what he saw, though it is implied that it has something to do with what lies beyond the larger mountain range that even the Old Ones feared. It is likely that this entity was an avatar of Yog-Sothoth.

The Dunwich Horror

Yog-Sothoth has some connection to the mysterious Old Ones mentioned in The Dunwich Horror (1929), but their nature, their number, and their connection to Yog-Sothoth are unknown. Nonetheless, they are probably allied to him in some way, since Wilbur Whateley, the half-human son of Yog-Sothoth, tried to summon them so that they could control Wilbur's more tainted twin and make it reproduce.

The Haunter of the Dark

Robert Blake calls on Yog-Sothoth to save him from the eponymous malign entity which he has let loose.

Myth and Legends

Yog-Sothoth knows all and sees all. To "please" this deity could bring knowledge of many things. However, like most beings in the mythos, to see it or learn too much about it is to court disaster. Some authors state that the favor of the god requires a human sacrifice or eternal servitude.


Yog-Sothoth is called upon from time to time to assist mortals in performing occult deeds or rituals. The most notable instances of these events are recorded in "The Case of Charles Dexter Ward" and "The Dunwich Horror."


One ritual involving Yog-Sothoth makes use of the "essential salts" of a deceased individual to resurrect them from the dead. The incantations involved with this are transcribed approximately as follows:

"Y'AI'NG'NGAH.YOG-SOTHOTH. H'EE-L'GEB. F'AI THRODOG. UAAAH". The incantation to put down the resurrected individual is the partial syllabic reverse of the first, and reads: OGTHROD AI'F. GEB'L-EE'H. YOG-SOTHOTH.'NGAH'NG AI'Y. ZHRO"


In one case involving the town of Dunwich, Yog-Sothoth is known to have been summoned for the purposes of impregnating a human female, who then gave birth to two partially-human children. The summoner was the husband/"father" of the Whateley family, who was known to have stood on a hill in a circle of stones with the Necronomicon while shouting the name of Yog-Sothoth from the summit.


...great globes of light massing toward the opening, and not alone these, but the breaking apart of the nearest globes, and the protoplasmic flesh that flowed blackly outward to join together and form that eldritch, hideous horror from outer space, that spawn of the blankness of primal time, that tentacled amorphous monster which was the lurker at the threshold, whose mask was as a congeries of iridescent globes, the noxious Yog-Sothoth, who froths as primal slime in nuclear chaos beyond the nethermost outposts of space and time!
H.P. Lovecraft
From across the Black seas of Infinity and beyond the mists of time, Yog-Sothoth watches and waits. For he is the guardian of the gateway between worlds and he alone holds the key to unlock the gate. For when the ancient rites have been spoken, and the lords of darkness have been awakened and summoned forth, then shall the gateway between the stars open once more.
The Necronomicon (about Yog-Sothoth)
Imagination called up the shocking form of fabulous Yog-Sothoth—only a congeries of iridescent globes, yet stupendous in its malign suggestiveness.
H.P. Lovecraft
It was an All-in-One and One-in-All of limitless being and self—not merely a thing of one Space-Time continuum, but allied to the ultimate animating essence of existence’s whole unbounded sweep – the last, utter sweep which has no confines and which outreaches fancy and mathematics alike. It was perhaps that which certain secret cults of earth have whispered of as YOG-SOTHOTH, and which has been a deity under other names; that which the crustaceans of Yuggoth worship as the Beyond-One, and which the vaporous brains of the spiral nebulae know by an untranslatable Sign…yet in a flash the Carter-facet realized how slight and fractional all these conceptions are.
H.P. Lovecraft and E. Hoffman Price (about Yog-Sothoth)
IT seemed to say, MY manifestations on your planet's extension, the Ancient Ones, have sent you as one who would lately have returned to small lands of dream which he had lost, yet who with greater freedom has risen to greater and nobler desires and curiosities. You wished to sail up golden Oukranos, to search out forgotten ivory cities in orchid-heavy Kled, and to reign on the opal throne of Ilek-Vad, whose fabulous towers and numberless domes rise mighty toward a single red star in a firmament alien to your earth and to all matter. Now, with the passing of two Gates, you wish loftier things. You would not flee like a child from a scene disliked to a dream beloved, but would plunge like a man into that last and inmost of secrets which lies behind all scenes and dreams. What you wish, I have found good; and I am ready to grant that which I have granted eleven times only to beings of your planet—five times only to those you call men, or those resembling them. I am ready to shew you the Ultimate Mystery, to look on which is to blast a feeble spirit. Yet before you gaze full at that last and first of secrets you may still wield a free choice, and return if you will through the two Gates with the Veil still unrent before your eyes.
Yog-Sothoth addressing Randolph Carter
Oh, I've seen Yog-Sothoth's human form all right. Trust me, there's no way his outfit isn't painted-on underwear. If it wasn't for one of his tentacles blocking the way, I almost have to see his birthday suit. Thanks God for small blessing.

  • H.P. Lovecraft humorously referred to the Cthulhu mythos as the "Yog-Sothothery".
  • George Olshevsky and Bruce Chilton named the nonconvex snub polyhedra after some other Great Old Ones, with the Small retrosnub icosicosidodecahedron as "Yog-Sothoth", them being the first to build an accurate physical representation of the polyhedron.
  • There are a few who are capable of conversing with him without going mad. One such is his personal chronicler, H.P. Lovecraft. Another is Hermaeus Mora, who shares many similarities to the Outer God.
  • He is the only Outer God to be portrayed in a benevolent way, as he was not always all evil and is willing to help those he deems worthy.
  • He once tried to lock Amatsu-Mikaboshi in the void but that proved to be a mistake as the empowered primordial easily overpowered the Old One in his domain forcing him to flee.
