Yog-Sothoth is a fictional cosmic entity from the works of H.P. Lovecraft, particularly featured in the Cthulhu Mythos. It is often described as an all-knowing being that exists outside of time and space, embodying the concept of the universe itself. Yog-Sothoth is typically depicted as a conglomeration of glowing spheres, representing its omnipresence and connection to all dimensions. In Lovecraft's stories, Yog-Sothoth is associated with forbidden knowledge and is often invoked in occult rituals. It is considered both a gate and a key, allowing access to other realms and realities. This duality makes Yog-Sothoth a significant figure in the exploration of cosmic horror and the unknown.
