Howard Phillips Lovecraft (August 20, 1890-March 15, 1937) known as H. P. Lovecraft was an American author of horror, fantasy and science fiction, especially the subgenre known as weird fiction. Lovecraft’s guiding aesthetic and philosophical principle was what he termed “cosmicism” or “cosmic horror”, the idea that life is incomprehensible to human minds and that the universe is fundamentally inimical to the interests of humankind.

Many roleplaying games have been created that use his literature as a setting, games such as Call of Cthulhu and Cthulhu Dark.
