Tarc

The Tarc were a sentient crustacean species, indigenous to the planet Hjaff. Standing at around two meters tall with four arms and a chitinous exoskeleton, they appeared intimidating to most humanoids, a reputation furthered by their ruthless and emotionless behavior. The Tarc, in fact, did not lack emotions, but believed them to be private and not to be shared with others. Fiercely protective of their culture and sovereignty, the Tarc saw other species as a threat to both of these and, as a result, were extremely isolationist as a society. The Tarc colonized the star systems around their homeworld, making the area a buffer between them and the rest of the galaxy and using their navy, the Ivlacav Gourn, to destroy any intruders. That practice led the species into conflict with the Galactic Empire during the Galactic Civil War.
