The Lisst'n were a sentient species that continually shed their skin. They were active in the galaxy dating from the time of Xim the Despot, circa 25,000 BBY. According to legend, Lyechusas, Xim's court poet and the most renowned Lisst'n dramatist, penned three trilogies on the life of the Despot from this time. In the early years of the Galactic Empire, the University of Rudrig, the sole university in the Tion Hegemony, had several luxury dermal autostripper services available for members of the Lisst'n species.
