Chiss

Originating on the cold world of Csilla in The Unknown Regions, the Chiss are largely unknown to the greater galactic community until five years after the Battle of Yavin, when a Chiss known as Grand Admiral Thrawn rallies the Imperial remnants and goes to war against the New Republic. Even then, the Chiss remain an enigmatic, secretive Species. Their origins are largely unknown, even to the Chiss themselves, though some scientists believe they are descended from an isolated Human colony lost to time.

The Chiss are technologically advanced, keenly interested in art and science, and skilled at mathematics. Though logical in their mindset, they are also appreciative of philosophy, and interested in other cultures. Given their xenophobic tendencies, it comes as no surprise that the Chiss use their understanding of non-Chiss cultures to gain a tactical advantage over potential adversaries.

Chiss society is highly ordered and structured. Rule of law is controlled and enforced by a small number of ruling "Families." These ruling families, also known as clans or houses, are more akin to different branches of government than to actual familial units. As a rule, a Chiss will never knowingly do anything to bring shame upon his or her family, for entire lines have been exiled for the actions of a single family member.

The culture of the Chiss is based on a strict code of conduct. As a rule, they do not attack an opponent unless they are attacked first. Thrawn ignores this imperative when he seizes control of the Imperial remnants, and consequently he is exiled from his people. Although most Chiss are peaceful, once embroiled in military conflict, they do not relent until their opponents are either totally destroyed, or completely subjugated.
