The Yog-Sothoth wiki last edited by JBL on 06/24/14 05:15PM View full history


Yog-Sothoth is an Outer God in the stories of H.P. Lovecraft and other authors. Yog-Sothoth is linked with all of time and space, but is sealed outside of the universe that humans inhabit. In Through the Gates of the Silver Key, Yog-Sothoth is described as an All-in-One and One-in-All of limitless being and self, allied to the essence of existence.


According to the stories The Horror in the Museum and The Lurker at the Threshold, Yog-Sothoth appears in this dimension as a congeries of iridescent globes "stupendous in its malign suggestiveness", from which it extrudes tentacles, eyes, mouths or whatever the need of the moment requires. In Lovecraft's 1928 story The Dunwich Horror, its spawn appear as an invisible mass of feelers, legs, eyes, stalked organs, and tentacles, made visible only for a second by the use of a magic powder. Kenneth Grant, an occultist who appears to take all this a lot more seriously than is good for him, says Yog-Sothoth is a manifestation of the darkest part of the psyche. Grant describes it as a gangrenous shade of green. with no upper skull at all, only a bloated mass that is its maggot-festering, naked brain, a madly gazing, giant's "Cyclops" eye ringed by octopoid palpi and shark teeth above a warty tyrannosaurus-like body covered in muck.

Yog-Sothoth's Avatars

Yog-Sothoth has avatars who live to serve the great deity.


Aforgomon was worshiped as the God of Time by many cultures due to its power to manipulate time and space. He is usually shrouded in a mysterious, blinding light and only shows himself to those who anger him.

Yog-Sothoth appears as a recurring villain in the Doctor who franchise known as "The Great Intelligence" in both the classic and revived shows that appeared in the episodes "The Abominable Snowmen" & "The Web of Fear" of the classic show and "The Snowmen", "The Bells of Saint John" & "The Name of the Doctor" of the revived show and was the main antagonist of series 7.

He also appeared in the direct-to-video spin-off episode "Downtime" and in the novels "Millennial Rites" & "All-Consuming Fire" as well as the video game "Doctor Who: Destiny of the Doctors".

This version of Yog-Sothoth was a being of the Pre-Universe and after that universe was destroyed he became a being without a physical body and became known as "The Great Intelligence".

In the classic show and in "Downtime" he used robotic Yeti as his soldiers and in the revived show he used used living Snowmen in the 2012 Christmas special "The Snowmen", robots called "Spoonheads" in "The Bells of Saint John" and strange creatures called "The Whisper Men" in "The Name of the Doctor".

Powers and Abilities

The god is omniscient and all-seeing and gaining favor with the entity can give one incredible and vast knowledge. However, the entity is so powerful that merely seeing it or learning too much about its existence would drive one insane and create disaster. In order to please Yog-Sothoth it is said by many that human sacrifice or lifetime commitment to its worship are required. Yog-Sothoth is, however, weaker than Azathoth.

All is one in Yog-Sothoth.
