Yog-Sothoth

"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."

- 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 "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..."

- H.P. Lovecraft and E. Hoffman Price "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

Yog-Sothoth is a vastly powerful cosmic entity from the works of H.P. Lovecraft, and is one of the Outer Gods, yet he is the second most powerful of them (behind Azathoth) - dwarfing the famous Cthulhu in the same scale that Cthulhu dwarfs humanity, and a truly cosmic menace that is beyond mortal comprehension. Yog-Sothoth is the embodiment 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.

History
According to the mythology of Lovecraft, Yog-Sothoth is a limitless cosmic horror that is connected with all of space and time yet is locked away from mainstream reality - the 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.

Like many Lovecraftian deities Yog-Sothoth has a number of avatars and even followers (such as the Chorazos Cult) by which to expand its influence and although classed as "evil" is technically an amoral character that is simply beyond our understanding of petty morality or sanity (indeed Lovecraft wrote in a very dark fashion that swayed away from moral absolutes and saw the universe as being cold and cruel by its very nature).

Description
Like many Lovecraftian gods, Yog-Sothoth has many different appearances throughout the various stories of the mythos, by various authors. However, there seems to 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.

​Powers
Yog-Sothoth is the second most powerful being in the Cthulhu Mythos​. Being the Outer God of time and space, Yog-Sothoth has control over all of the Spacetime continuum. He is also Omniscient and he knows and sees all. He exists outside of the Universe in an Omnilock. The entity is so powerful that merely seeing it or learning too much about its existence would drive one insane and create disaster.

Appearances
Yog-Sothoth's name was first mentioned in Lovecraft's novella The Case of Charles Dexter Ward (written 1927, first published 1941). He goes on to be the driving force of the short story The Dunwich Horror, in which he fathers twin children with a human. He later serves as the secondary antagonist of At the Mountains of Madness in connection to the thing beyond the mountains that even the Elder Things fear.

​Cthulhu Mythos
Yog-Sothoth is coterminous with all time and space yet is supposedly locked outside of the universe we inhabit. Its cosmic nature is hinted at in a passage from Through the Gates of the Silver Key (1934) by Lovecraft and E. Hoffmann Price.

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.

According to the genealogy Lovecraft devised for his characters (later published as "Letter 617" in Selected Letters), Yog-Sothoth is the offspring of the Nameless Mists, which were born of the deity Azathoth. Yog-Sothoth mated with Shub-Niggurath to produce the twin deities Nug and Yeb, while Nug sired Cthulhu through parthenogenesis. In Lovecraft's short story The Dunwich Horror, Yog-Sothoth impregnates a mortal woman, Lavinia Whateley, who then gives birth to twin sons: the humanoid Wilbur Whateley, and his more monstrous unnamed brother.

At the end of Lovecraft's late story The Haunter of the Dark, the protagonist Robert Blake calls on Yog-Sothoth to save him from the eponymous malign entity which he has let loose.

Beyond the Gates of the Silver Key
In this story 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 believed that this entity was 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 Case of Charles Dexter Ward
In The Case of Charles Dexter Ward, its name is part of an incantation that could revive the dead (and with some of the syllables reversed, slay the creature raised):

Y'AI'NG'NGAH YOG-SOTHOTH H'EE-L'GEB F'AI THRODOG UAAAH

Aforgomon
Aforgomon is an obscure avatar of Yog-Sothoth invented by Clark Ashton Smith. He 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.

The Lurker at the Threshold
This is the name given to Yog-Sothoth in August Derleth and H. P. Lovecraft's novel The Lurker at the Threshold. In the story, Alijah Billington describes Yog-Sothoth's appearance as "...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!"

'Umr at-Tawil
'Umr at-Tawil (Arabic عمر الطويل) The [Most Ancient and] Prolonged of Life), also spelled Tawil At-U'mr or Tawil-at'Umr, is described as an avatar of Yog-Sothoth in the story "Through the Gates of the Silver Key", by Lovecraft and E. Hoffman Price. In the story, 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.

The Eater of Souls
In The Illuminatus! Trilogy by Robert Anton Wilson and Robert Shea, Yog-Sothoth is the Eater of Souls. ""...That the chief of these beings is referred to in the Pnakotic Manuscripts and the Eltdown Shards as Iok Sotot, "Eater of Souls," suggests that it was some energy or psychic vibration of the dying victim that the lloigor needed..." "...in private, of course, they worshipped Iok-Sotot, who became the Yog-Sothoth of the Necronomicon.""

This identification is carried forward in Grant Morrison's Zenith series for 2000 A.D., and in Charles Stross' novelette A Colder War where the entity if summoned is able to instantly consume the minds of entire planets: "...There is life eternal within the eater of souls. Nobody is ever forgotten or allowed to rest in peace. They populate the simulation spaces of its mind, exploring all the possible alternative endings to their life. There is a fate worse than death, you know..."

Trivia

 * It is a common misconception that Yog-Sothoth is more powerful than Azathoth. This is not true, however, as Yog-Sothoth is a part of Azathoth's dream reality (As evidenced by XXII. Azathoth)
 * Despite this, Yog-Sothoth is larger and more intelligent than Azathoth as Yog-Sothoth is omniscient and Azathoth is mindless and Yog-Sothoth is omnipresent and all of existence.
 * The Blood Red Glister, one of the major villains of The Edge Chronicles, may have been based off Yog-Sothoth, because the Glister's physical appearance, nature and morphology are identical to Yog-Sothoth's.
 * Chaos in The Power of Five is also partially based on Yog-Sothoth, because Chaos is a featureless mass of shapeshifting darkness with vague tentacles when disembodied, but Chaos can take on any forms, including a form similar to Cthulhu.
 * The final form of Metroid Prime can be said to be based on Yog-Sothoth, because of her tentacled nature and her eldritch form.
 * He is the only Lovecraft God to be portrayed in a benevolent way as he was not at all evil in Beyond the Gates of the Silver Key and is willing to help those he deems worthy.
 * Yog-Sothoth is the largest villain on Villains Wiki ​as he is all of existence.
