The Chiss are one of the races from the Unknown Regions, who gained prominence during the time of the New Republic, largely due to Grand Admiral Thrawn (for a wider audience familiar with more than just the films), who served the Empire and was perhaps one of the greatest tactical geniuses the galaxy has ever known. The Chiss are very similar to humans; their main differences are their blue or, sometimes, indigo skin, red eyes without pupils, and matte black hair. The Chiss are usually calm and reserved, essentially cold and unemotional. Although, like all others, they experience anger, joy, hatred, or sorrow, they hide their feelings. The height of a Chiss ranges from 1.7 meters to 2 meters. The Chiss homeworld is Csilla. Chiss names are quite long and difficult for an ordinary person to pronounce. Mitt'ra'nu'uruodo is Grand Admiral Thrawn's full name.
This race is fully playable and can sense the Force.
