Decoding Vril, Agartha, and Hyperborea: The Internet's Deepest Conspiracy Theories

This post directly asks for an explanation of niche, yet recurring, conspiracy theory terms (Vril, Agartha, Hyperborea). These concepts have a rich, often controversial, history tied to occultism, esoteric Nazism, and hollow earth theories, and they frequently resurface in fringe online communities and pop culture. A content piece explaining their origins, evolution, and modern relevance would appeal to a curious audience interested in understanding internet phenomena, historical conspiracies, or alternative beliefs.
