Chiss

The Chiss were a tall, blue-skinned Near-Human civilization from the planet Csilla in the Unknown Regions, best known to most Humans as the people to which Grand Admiral Thrawn belonged. Due to the remote position of their home territory in the Chiss Ascendancy they remained largely an enigma to the rest of the galaxy, and contact with outsiders was limited even in the days of the Galactic Alliance.
