As World War II rages, the SS Karotechia, is calling upon the obscene powers of the Cthulhu Mythos to ensure a Nazi victory, meddling in powers they do not understand and cannot hope to control.
Thule, the Nazi Atlantis, legendary home of Aryan superbeings that ruled prehistory. Thule was supposed to be a Nazi myth, but when a defector from the SS occult sciences division, the Karotechia, brings proof of Thule's reality, Delta Green's course is clear: the alien city and its technological and occult secrets must be denied to the enemy at all costs. But the true masters of Thule are fighting their own war.
A traitor from the past endangers their eons-old plan to shape the future. The survival of mankind depends on the fate of Thule; but to destroy Thule or save it? Which choice will save mankind?
These are the glory days of Delta Green. They are also humanity’s darkest hour.
