A entity for
H.P. Lovecraft's short story "The Call of Cthulhu" who also appears in several later stories, though
CC is the only
one that focuses on him. Cthulhu is a extraterrestrial being referred to as "Great Old Ones" and is generally associated with madness. It is said to have "yielded simultaneous pictures of an octopus, a dragon, and a
human caricature.... A pulpy, tentacled head surmounted a grotesque scaly body with rudimentary wings." While no specifics of it's height have been given, in the Climax of Call of Cthulhu, when some sailors stumble upon the formerly-sunken city of R'lyeh, the city in which Cthulhu is said to be sealed, they accidentally release the
monster, and
one said it was "A mountain that walks or stumbles", implying it's enormous height.
For some reason, Cthulhu along with the other Great Old Ones have been sealed away, and is said that Cthulhu one day will awaken and release the Great Old Ones and they will resume the rule of
Earth, and there will be a "Holocaust of freedom and ecstasy". the Great Old Ones telepathically talked with the earliest
humans, and started the infamous
Cult of Cthulhu.
many real life cults have been started and can be found on the
internet. I'm not sure which scares me more, the Cthulhu cults, or the other religions.
