The Great Old Ones ruled the earth eons before the age of humankind. Remains of their cyclopean cities can still be found on remote islands in the Pacific¸ buried amid the shifting sands of vast deserts¸ and in the frigid recesses of the polar extremes. Originally they came to the world from out of the sky. Now they sleep - some deep within the enveloping earth and others beneath the eternal sea¸ in the drowned city of R'lyeh¸ preserved from the waters by the spells of mighty Cthulhu. When the stars are right they will rise¸ and once again walk the earth. "Call of Cthulhu" is a roleplaying game based on the works of H. P. Lovecraft¸ in which ordinary people are confronted by the terrifying beings and forces of the Cthulhu Mythos. Players portray investigators of things unknown and unspeakable. Except for dice¸ everything needed for play is included in this book.
