Cthugha is a fictional deity in the Cthulhu Mythos genre of horror fiction. He first appeared in August Derleth's 1944 short story "The House on Curwen Street".
|“||He hung motionless in a black, forbidding sky and at first thought he was suspended somewhere in the intrasolar deeps much closer to the Sun than on Earth. But then he realized that the dully gleaming orb which floated before his dreaming vision was not the Sun. Ugly dark blotches mottled the dull orange surface and great columns of spinning flame arced around the rim.... [He watched] the titan sunspots drift slowly across the hideous disc, at times growing larger and merging into great gaping chasms in the fiery atmosphere, while at others dwindling almost to nothingness.... Something was stirring deep within that fiery atmosphere; something monstrous that roared an insatiable anger against the chains of the Elder Gods which had bound it there for an eternity.... Unable to resist, utterly powerless to control his movements, he was diving headlong towards that ravening chaos, that age-old intelligence which was Cthugha.||„|
