Vril
Vril, the Power of the Coming Race is an 1871 novel by Edward Bulwer-Lytton, originally printed as The Coming Race. Many readers believe that its account of a superior subterranean master race and the energy-form called "Vril" is accurate, to the extent that some theosophists accepted the book as truth. A popular book, The Morning of the Magicians (1960) suggested that a secret Vril Society existed in pre-Nazi Berlin.
