The Black Sun Dimension is a dimension parallel to our own. It is very unstable, drawing bits and debris, and even life forms into the central dominating feature, the Black Sun itself. The Nazis stumbled onto this destructive dimension, seemingly due to locating the first Thule Medallion. They began to develop machines to harness the dimension's power. It resembles the Veil, albeit with a Black Sun where the normal sun might be; this sun can be seen to draw matter into it, and causes the swirling trails of wreckage spiraling into the sky which are visible in the Veil. Unlike the Veil, it does not bear any relationship to the real world. The only parts seen being drifting platforms suspended over a black void.
