The Vril Society is a troublesome topic because there's no authentic proof that this secret society really existed, even though there's no shortage of people who claim that it did. What makes the Vril Society really weird is that it started out as a science fiction story.
The Vril Society was founded as "The All German Society for Metaphysics" in to explore the origins of the Aryan race, to seek contact with the "hidden masters" of Ultima Thule, and to practice meditation and other techniques intended to strengthen individual mastery of the divine Vril force itself.
They believed that whoever becomes master of the Vril will be the master of himself, of others around him and of the world. The belief was that the world will change and the "Lords" will emerge from the center of the Earth. Unless we have made an alliance with them and become "Lords" ourselves, we shall find ourselves among the slaves, on the dung-heap that will nourish the roots of the cities that will arise.
