The Chiss are a proud and highly intelligent species, valuing a knack for strategy and subterfuge over brute force. Although isolated in the Unknown Regions of the galaxy within their so-called “Chiss Ascendency,” the Chiss were singled out by the Empire as potential servants and allies because of their outsider status and their relative lack of moral qualms.
It is not that Chiss are by nature evil, but that they value pragmatism and efficiency and recognize both those qualities reflected in the Empire. While as a nonhuman, non-Sith species, Chiss are regarded as second-class citizens within the Empire, the Chiss Ascendancy is permitted self-governance and supporters of a more diverse Empire often use the Chiss as an example of what the Empire can accomplish by welcoming other species. A few rare Chiss have even achieved official rank in the Imperial military and Imperial Intelligence.
