History
The Ogdru Jahad, also known as the Seven Gods of Chaos, were locked away in crystal shells in an alternate dimension, where they awaited the fateful day of their return. SS Colonel Johann Schmidt, a man fascinated by both Hebraic religion and Norse mythology, believed both of these "universes" to be no sort of legend, but actually real history recorded by ancient human whose meaning was lost in time with the advance of human creations.

Schmidt went to found the HYDRA society, a cult disguised as a weapons division for the Nazi Party under the command of Schmidt himself. He did not act alone, and although most of HYDRA's members were men who worked out of genuine care for for the Third Reich, some few select knew of Johann's plans.
