Dorn was a captain in Darth Krayt's Galactic Empire's Navy during the Second Imperial Civil War; he was a male Human. He was in command of the Pellaeon-class Star Destroyer called the Dauntless, and also the offspring of Governor Vikar Dorn from Munto Codru. In the year 137 ABY, he and his crew feigned a defection to Roan Fel's Galactic Empire faction, which was situated on Bastion. This defection was actually a scheme concocted by Darth Maladi, who headed up Sith Intelligence and Assassination. The purpose of the plan was to enable the Sith Lord Darth Kruhl to get into the Imperial Headquarters and assassinate Emperor Fel. Following Kruhl's failure and the exposure of their plot, Dorn and his whole crew were executed.
