The Case of Charles Dexter Ward
The cosmic entity "Yog-Sothoth" was first mentioned in "The Case of Charles Dexter Ward" (written 1927, first published 1941). The being is said to take the form of a conglomeration of glowing spheres. It is an all-knowing deity, which means it knows the past, present, and future. 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 this passage from "Through the Gates of the Silver Key" (1934) by Lovecraft and E. Hoffmann Price:
