The Vril-ya are a race of beings described in the novel titled "Power of the Coming Race". The book was originally published anonymously but was known to be written by Edward Bulwer-Lytton. (1871)
Lytton describes Vril-ya as a subterranean race of super beings sometimes said to resemble angels. The women of this race are known to be larger in size and more powerful than their smaller in stature male counterparts. Therefore the females are both mentally and physically the dominant sex. Vril-ya are descendants of an antediluvian civilization who live in networks of subterranean caverns linked by tunnels.
Many early readers and some theosophists believed Vril and the Vril-ya beings are real and the description provided in his writings is accurate. Since 1960 there has been a conspiracy theory about a Vril Society.
Further research of Vril will also lead you to Maria Orsic (also known as Maria Orchitsch) a famous medium who became the leader of the Vril Gelleschaft.
