In the 1940's Raymond A. Palmer was the editor of a science fiction magazine called Amazing Stories. The magazine did well and was big among science fiction fans. In March of 1945 a man named Richard S. Shaver who had been in and out of prison and mental homes submitted a science fiction story about a race of creatures who used to live on earth, but were forced to live underground because the suns radiation was too intense. They degenerated into deranged robots or "deros" for short. Palmer published the story as truth and it was a big hit with his fans. Palmer realized that he could get an occult following if he published crazy science fiction as truth, and that he could make a lot of money off of gullible people. Sales were way up, and so were the profits. For the next year Palmer had Shaver write up quick stories that he would rewrite into elaborate fantasies about this make believe race. They made money like this for a while, and it was always a big joke to Palmer who openly spoke about it often. Many years later Dr. York realized he could make money off of gullible people with the same old science fiction story by publishing it as fact.
He did just that and added the fictional story of the underground Deros to his scrolls and perpetuated the knowledge as indisputable fact. Unfortunately the majority of his followers don't research his claims any deeper than the scrolls he writes them in, so they carry on their lives feeling as though they have a hidden knowledge that most people don't have. When in reality they are living in a delusion created by an ex r&b singer.York is as smooth at hustling his people as he was seducing women on his albums, and he will continue to live lavishly as a multi millionaire, at their expense.
