Shub-Niggurath is a fictional deity from the Cthulhu Mythos, a shared universe created by writer H.P. Lovecraft and expanded by other authors. Often referred to as the "Black Goat of the Woods with a Thousand Young," Shub-Niggurath is associated with fertility, nature, and the chaotic aspects of the universe. In the Mythos, Shub-Niggurath is not typically depicted directly but is instead invoked in various rituals and stories. The entity is often linked to themes of creation and destruction, embodying the duality of life and death in a cosmic context.
