Some of the darkest hints in all of H.P. Lovecraft's Cthulhu Mythos relate to what will happen after the Old Ones return and take over the earth. In "The Dunwich Horror," the semi-human half-breed Wilbur Whateley speaks in his diary of travelling to nonhuman cities at the Earth's magnetic poles "when the Earth is cleared off," and hints at his own promised "transfiguration." Very few Mythos stories have ever touched on this. What happens when the Stars Are Right, the sunken city of R'lyeh rises from beneath the waves, and Cthulhu is unleashed upon the world for the last time? What happens when the other Old Ones, long since banished from our universe, break through and descent from the stars? What would the reign of Cthulhu be like, on a totally transformed planet where mankind is no longer the master?
It won't be simply the end of everything. It will be a time of new horrors and of utter strangeness. It will be a time when humans with a "taint" of unearthly blood in their ancestry may come into their own. It will be a time foreseen only by authors with the kind of finely honed imaginative visions as those included in Cthulhu's Reign
