Choronzon Club
From GURPSworld Wiki
The Temple of Choronzon is an occult organization founded in 1922. Initially dedicated to developing and teaching a "shortcut to initiation," over the years the group evolved into an organization of eclectic magicians dedicated to experimentation and exploration among the outer realms of occult knowledge. Their primary influences are Thelema, Vodun, Neo-Pythagoreanism, and Gnosticism. They are one of the few small occult societies to survive the 1930s.
California Chapter
A chapter of the club known as "the Kali-Fornian Chapter" is located in Los Angeles. It is thought to be headed by Freddie Gumm and uses the Caissa Chess Club of Los Angeles, located in the Scientology Author and Editorial Services building. The Caissa Chess Club was founded in 1945 by L. Ron Hubbard and Jack Parsons. It is not known how many members the two organizations share or if there is any connection beyond the superficial, nor is it known if the connection dates back to the origins of the chess club, though Hubbard and Parsons are known to be interested in magic and the occult.
