Aryan

Aryans, according to Nazi ideology, were the superior race to which Germans belonged. As such, they hoped to rid the world of non-Aryans.

In an alternate timeline, extermination camps were a way of dealing with non-Aryans, though in 1944, Vosk suggested to a German General that they could create a deadly water-borne pathogen targetting non-Aryans.

In a World War II holoprogram in 2374, a German Kapitän told Karr that German blood was pure, and that "degenerate races" had brought corruption to their land, hence the need for Europe to be "purified".
