Deep in the forlorn reaches of the ocean is the lost city of R'lyeh, where the great Cthulhu sleeps and dreams, waiting for the eon when the stars are right and the Great Old Ones will wander the earth again. There in those lightless depths misshapen and disturbing creatures chant lullabies for their master, and strange, glowing fish pay their reverence.
