Yog-Sothoth

Yog-Sothoth (The Lurker at the Threshold, The Key and the Gate, The Beyond One, Opener of the Way The All-in-One and the One-in-All) is a fictional character in the Cthulhu Mythos. The being was created by H.P. Lovecraft and first appeared in his novella The Case of Charles Dexter Ward. The being is said to take the form of a conglomeration of glowing bubbles.

Yog-Sothoth also occasionally appears in fiction outside the Cthulhu Mythos milieu. The Illuminatus! Trilogy by Robert Anton Wilson and Robert Shea, Yog-Sothoth describe as an extradimensional entity, whose attributes differ widely from those described in the Mythos. Worshipped as a god by some incarnations of the Illuminati, it is known as the Eater of Souls for its habit of feeding from human sacrifices. It is bodiless and invisible, but can possess humans, and can be imprisoned in pentagonal shapes; for several decades, it was imprisoned in The Pentagon by the Illuminati, and fed on traffic fatalities.

Other non-Mythos appearances are allusions or in-jokes. Terry Pratchett's Discworld novel Moving Pictures mentions an "outerdimensional being" named Yob Soddoth. A graffito in Stephen King's 1991 book Needful Things proclaims "Yog-Sothoth Rules," while a sign in his 1980 short story "Crouch End" reads "Yogsoggoth." "Eggs Sothoth" are served in H.P.'s Cafe, mentioned several times in the novels of Christopher Moore. In Zenith, a series in the comic 2000 AD, Iok Sotot is one of the Many-Angled Ones, extradimensional entities who correspond, in the Zenith universe, to the ancient gods described by Lovecraft.

The Doctor Who novel Millennial Rites by Craig Hinton identifies the Doctor Who villain the Great Intelligence as, in actuality, Yog-Sothoth.
