Lieutenant Dorss was a male Kel Dor customs officer stationed at the spaceport in Dor'shan, the capital city of the planet Dorin, in 43 ABY. When recently exiled Jedi Grand Master Luke Skywalker and his son, Jedi Knight Ben Skywalker, traveled to Dorin to speak with Master Koro Ziil of the Baran Do—an order of Force-users who lived on the planet—in hopes of finding out more about former Jedi Knight Jacen Solo's fall to the dark side of the Force and transformation into Darth Caedus, Dorss, along with Sergeant Vult, inspected the Jedi's starship, the Jade Shadow.
