Agartha is a mythical kingdom supposedly located in the center of the Earth. Its entrance lies somewhere deep in the Himalaya. Nepalese outfitters would make a fortune guiding tours there, but so far, none have attempted to open up this market. Yet the subterranean kingdom links all the continents on Earth through an incredible network of tunnels, created by a race of powerful beings called the Old Ones. They far surpass humans physically and spiritually, as well as in intelligence and technology.
