The Breakaway Civilization - Agartha Shambhala New Swabia

Agartha is a legendary city that is said to be located in the Earth's core.

Many have connected the Vril Society with UFOs. Among their claims, they imply that the society may have made contact with an alien race and dedicated itself to creating spacecraft to reach the aliens. In partnership with the Thule Society and the Nazi Party, the Vril Society developed a series of flying disc prototypes.

With the Nazi defeat, the society allegedly retreated to a base in Antarctica and vanished into the hollow Earth to meet up with the leaders of an advanced race inhabiting inner Earth.
