H. P. Lovecraft created a number of fictional deities throughout the course of his literary career, including the "Great Old Ones" and the "Elder Things", with sporadic references to other miscellaneous deities (e.g. Nodens) whereas the "Outer Gods" are a later creation of other prolific writers such as August Derleth, who was credited with formalizing the Cthulhu Mythos.
As it is known in the mythos, the Outer Gods are ruled by Azathoth, the "Blind Idiot God", who holds court at the center of the universe. A group of Outer Gods dance rhythmically around Azathoth, in cadence to the piping of a demonic flute. Among the Outer Gods present at Azathoth's court are the entities called "Ultimate Gods" in The Dream-Quest of Unknown Kadath (called Lesser Outer Gods in the Call of Cthulhu RPG), and possibly Shub-Niggurath, the "Black Goat of the Woods". Yog-Sothoth, the "All-in-One", co-rules with Azathoth and exists as the incarnation of time in the cosmos, yet is somehow locked outside the mundane universe. Nyarlathotep, the "Crawling Chaos", is the of the Outer Gods, existing as the incarnation of space and functions as an intermediary between the deities of the pantheon and their cults. The only Outer God to have a true personality, Nyarlathotep possesses a malign intellect and reveals a mocking contempt for his masters.

Aiueb Gnshal (The Eyes Between Worlds, The Child-Minded God) is a mysterious Outer God, who has his abode in a forgotten temple located somewhere in Bhutan. He appears as a formless black void, with seven pulsing orb-like eyes, and is mainly worshiped by ghouls, which tribute him in a defiled cult described in the mysterious Cambuluc Scrolls of the wizard Lang-Fu, dating back 1295 AD. Peering through the eyes of this god, after a hideous and devastating ritual, allows one to see straight into Azathoth's court. It is rumoured that the powers of Mongolian warlord Temujin, was a favour of Aiueb Gnshal.
