Fantasy Bedtime Hour is public-access television cable TV program on San Francisco channel 29.
 It can be described by its tagline, "Two girls in bed ill equipped to handle fantasy novel concepts discuss Lord Foul's Bane" (the novel by Stephen R. Donaldson).
Rodney Collin (26 April 1909 – 3 May 1956) was a British writer in the area of spiritual development.
 His work was heavily influenced by his teacher P. D. Ouspensky and, through him, G. I. Gurdjieff and their system of spiritual development.
 Collin was one of the most well known of Ouspenky's students and a prolific writer.
 He met Ouspensky in 1936.
 "Rodney Collin immediately recognised that he had found what he had been searching for in his reading and travels.
 From then on he dedicated all his time to the study of Mr Ouspensky's teaching."
 Collin's best known work, "The Theory of Celestial Influence", is an ambitious attempt to unite astronomy, physics, chemistry, human physiology and world history with his own version of planetary influences.
Pyotr Demianovich Ouspenskii (known in English as Peter D. Ouspensky, Пётр Демья́нович Успе́нский; 5 March 1878 – 2 October 1947), was a Russian mathematician and esotericist known for his expositions of the early work of the Greek-Armenian teacher of esoteric doctrine George Gurdjieff, whom he met in Moscow in 1915.
 He was associated with the ideas and practices originating with Gurdjieff from then on.
 He shared the (Gurdjieff) "system" for 25 years in England and the United States, having separated from Gurdjieff in 1924 personally, for reasons he explains in the last chapter of his book "In Search of the Miraculous".
Daughter of Regals is a fantasy novella by Stephen R. Donaldson.
 It tells of a young woman called Chrysalis, the nominal ruler of three kingdoms who is about to come of age.
 To claim her throne, Chrysalis must exhibit the magical abilities of her ancestors the Regals - who combined the attributes of human men and mythical creatures - or else her dominions will collapse into civil war.
 While the kings of the individual kingdoms plot against her, Chrysalis struggles to release the magic inherent within her and claim her inheritance.
The Atlas of the Land by Karen Wynn Fonstad provides a cartographer's point of view to the fictional world known as "the Land" from Stephen R. Donaldson's fantasy novel series "The Chronicles of Thomas Covenant".
