I was very surprised when I ran across these titles at a neat local used bookstore. First I found a decent copy(there is some hightlighting inside) of Guy Debord's situationist masterwork The Society of the Spectacle.
Barkun writes that "Shaver was hospitalized briefly for psychiatric problems in 1934, but there does not appear to have been a clear diagnosis."Barkun notes that afterwards, Shaver's whereabouts and actions cannot be reliably traced until the early 1940s.
This article on Devil's Tower caught my attention. Inspiration to Close Encounters of the Third Kind?
Shaver wrote of extremely advanced pre-historic races who had built cavern cities inside Earth before abandoning Earth for another planet due to damaging radiation from the Sun. Those ancients also abandoned some of their own offspring here, a minority of whom remained noble and human "Teros", while most degenerated over time into a population of mentally impaired sadists known as Deros—short for "detrimental robots." Shaver's "robots" were not mechanical constructs, but were robot-like due to their savage behavior.
These Deros still lived in the cave cities, according to Shaver, kidnapping surface-dwelling people by the thousands for meat or torture. With sophisticated "ray" machinery that the great ancient races had left behind, they spied on people and projected tormenting thoughts and voices into our minds (reminiscent of schizophrenia's "influencing machines" such as the Air loom). Deros could be blamed for nearly all misfortunes, from minor "accidental" injuries or illnesses to airplane crashes and catastrophic natural disasters. Women especially were singled out for brutal treatment, including rape, and Dash notes that "Sado-masochism was one of the prominent themes of Shaver's writings." Though generally confined to their caves, Shaver claimed that the Deros sometimes traveled by spaceships or rockets, and had dealings with equally evil extraterrestrial beings. Shaver claimed first-hand knowledge of the Deros and their caves, insisting he had been their prisoner for several years.
