ACCORDING TO THIS, AND MANY OTHER PAPERS I have found, the NAZI GERMAN military organizations, "The Black Sun" and the "Thule Society" did travel to, and have contact with the people living in the Inner Earth {The Hollow Earth}. There are many descriptions of the Hollow Earth and the people there. Here, and for the next two pictures, you can see the maps of the Inner Earth - - the names of the continents and the depicted land mass.
