Cthulhu Mythos deities

The Cthulhu Mythos is a group of creatures, gods, and monsters in a world created by horror writers. The most famous of these creatures is Cthulhu, who is described as a giant, octopus-like monster. Other gods and monsters in the Cthulhu Mythos include the ancient gods Yog-Sothoth and Hastur, the monster Shub-Niggurath, and the Old Ones, a race of alien creatures that live outside the boundaries of the universe. All of these creatures are imagined by writers, and don't actually exist in real life.
