The Cthulhu Mythos is a shared fictional universe, based on the work of American horror writer H. P. Lovecraft. The term was first coined by August Derleth, a contemporary correspondent of Lovecraft, who used the name of the creature Cthulhu – a central figure in Lovecraft literature[1] and the focus of Lovecraft's famous short story The Call of Cthulhu (first published in pulp magazine Weird Tales in 1928) – to identify the system of lore employed by Lovecraft and his literary successors.
