For several hundred years, the Empire is the sole government of humanity. Among its many worlds is Sauron, where the culture has grown militaristic and adheres to a literal interpretation of the philosophy of Nietzsche, namely that "man is something to be surpassed." In service of this aim, they engage in extensive genetic modification and eugenic breeding programs to turn themselves into supersoldiers known in the galaxy at large as the Sauron Supermen. Bristling under Imperial hegemony, in the 27th century they lead several worlds into open revolt.
Sauron Supermen are large, warrior-like humanoids.
