Yog-Sothoth is a cosmic entity in the fictional Cthulhu Mythos. Yog-Sothoth exists outside of all time and space, simultaneously embodying all of it. It is described as the "Supreme Archetype", all other things that exist simply being facets of him. Yog is viewed as the second most powerful of the Outer Gods, only behind Azathoth. It is also one of the few that can be viewed as benevolent in some cases, as it seems to have no real set allegiance and will help those who it views as worthy of its attention.
