Yog-Sothoth, also The Lurker at the Threshold, Opener of the Way, Beyond-One, All-in-One and One-in-All, is an Outer God from H.P. Lovecraft's Cthulhu Mythos.


Manifesting most commonly as a celestial collection of glowing spheres, Yog-Sothoth lives in co-existence with the entirety of time and space of all continua; as such, it knows all and sees all, yet is still locked out of the universe by unknown means. Despite this, 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.


As Yog-Sothoth is unable to manifest in the multiverse, it must rely on a series of avatars to do its bidding. Some of these are included below.


One of the more obscure of Azathoth's avatars, Aforgomon is worshiped by many cultures as the God of Time; it possesses the ability to manipulate not only time but also space. Almost nothing is known of the appearance of this being, as it only shows itself to those that have angered it; such individuals do not tend to live long.

'Umr at-Tawil

Another being with a connection to time, 'Umr is said to preside over the eternal halls beyond the Gate of the Silver Key and the incredibly powerful Ancient Ones that live there. This aspect is said to appear as the outline of a human veiled behind a shimmering curtain. This is one of Yog-Sothoth's more benevolent avatars.

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.
