"Iä! Iä! Cthulhu fhtagn!"

• Cthulhu chant

High Priest of the Great Old Ones, The Sleeper of R'lyeh or The Great Dreamer, all is the name of Cthulhu. The Great Old One of great power who lies in a death-like slumber beneath the Pacific Ocean in his sunken city of R'lyeh. Awaits to be awakened to bring madness to all living things.

The most detailed descriptions of Cthulhu are based on statues of the creature. One, constructed by an artist after a series of baleful dreams, is said to have "yielded simultaneous pictures of an octopus, a dragon, and a human caricature...A pulpy, tentacled head surmounted a grotesque and scaly body with rudimentary wings."
