Who are they?Edit
A human-like race that resemble the Native Americans in the United States of the area, though they are actually extraterrestrials who arrived in prehistoric times. They are immortal and have powerful psionic abilities, including telepathy and the ability to dematerialize at will. In ancient times, the people of K'n-yan traded with the humans of the surface world. But when geological calamities caused the continents of Atlantis and Lemuria to sink into the ocean, the people of K'n-yan sequestered themselves below ground, thereafter having no further dealings with the outer world.
They are also technologically advanced, using machines that employ principles of atomic energy, though they have largely abandoned their mechanized culture finding it unfulfilling.
The Brothers of The Yellow Sign are claimed to have decended from the natives of K'n-Yan. If this is the case it seems to be that the worship of Hastur, not the most important of the gods, has found the surface a more fertile ground to spread its worship (and particualr brand of madness).
Of similar interest are the Kuen-Yuin, immortal sorcerers who follow a pantheon which also includes Hastur and Cthulhu. That this is not too different from the immortal psychics of K'n-Yan suggests a connection (other than different authors inspiring each other). Perhaps the Kuen-Yuin also decend from an extraterrestrial background. And perhaps, in times long past, Cthulhu and Hastur were worshipped side-by-side, and not recognised as enemies as seems to be the case now.
What are their methods?Edit
When the denizens of K'n-yan rejected their mechanistic lifestyle, they turned to a sort of socialistic aristocracy, controlled by a ruling class made "highly superior through selective breeding and social evolution".
What are their beliefs?Edit
The race follows a pantheon of gods, the two most important ones being Tulu (Cthulhu) and Yig. The denizens of K'n-yan often place idols of these deities in near proximity, as in the following passage from The Mound: (In) a pair of vast niches, one on each side, (the) monstrous, nitre-encrusted images of Yig and Tulu squatted, glaring at each other across the passage as they had glared since the earliest youth of the human world. Other deities include Shub-Niggurath, Nug and Yeb, Ghatanothoa, and the Not-to-Be-Named One (presumably Hastur).
