The Cthulhu Mythos is a collection of 23 loosely connected short stories by H. P. Lovecraft, one of the earliest masters of dark fantasy and horror. From "Dagon" to "The Call of Cthulhu" to "The Haunter of the Dark," each story connects to the ancient cosmic entities known as the Great Old Ones, buried in a deep sleep beneath the earth and incomprehensible to mankind.
