Great Unknown (fortress)

The Great Unknown was the name given to a fortress of the extinct Great Ones of the Foitani Empire. In the late 30th century CE (standard Earth calendar), expeditions from various Foitani groups tried to study this fortress, only to have any members who came to close to it, go into a killing madness.

On one occasion, Oderni Foitani made a long-distance study of the fortress. While they were doing this, Rof Golani Foitani from Odern's long-time enemy showed up, and a shooting war began between the two expeditions.
