The Lovecraftian Mythos is a shared fictional universe created by writer H.P. Lovecraft and expanded by other authors. It features a pantheon of ancient, cosmic entities, such as Cthulhu, that exist beyond human comprehension, often leading to madness and despair for those who encounter them. Central to the Mythos is the idea that humanity is insignificant in the grand scheme of the universe. The stories often explore themes of forbidden knowledge and the fragility of sanity, inviting readers to confront the unknown and the terrifying possibilities that lie beyond our reality.
