The Eirraucs were an alien race distinguished by its six limbs and long, four eyed faces. Native to the planet Eirrauus, the Eirraucs move cross the plains of their homeworld via a "leaping run," employing the hind and middle pairs of legs to move about. The middle pair of limbs could also be used as arms, to assist the front arms in manipulation. The Eirrauc were omnivorous, feeding on grasses and fruits as well as carrion. They gathered food with their tongues. A peaceful people, the Eirrauc were unprepared to defend themselves against the Empire, and were swiftly subjugated and enslaved.
