The Coming Race
Vril is a substance described in Edward Bulwer-Lytton's 1871 novel The Coming Race, which was later reprinted as Vril: The Power of the Coming Race. The novel is an early example of science fiction. However, many early readers believed that its account of a superior subterranean master race and the energy-form called "Vril" was accurate, to the extent that some theosophists accepted the book as truth. Furthermore, since 1960 there has been a conspiracy theory about a secret Vril Society.
