Graul, a male Human commander, served the rebuilt Sith Empire as an officer during the era known as the Cold War.
Graul aided Lord Sadic in 3643 BBY by helping to develop the Mark I Power Guards on the moon of Nar Shaddaa. He found himself in the Red Light Sector when he came across the Hero of Tython, who was attempting to sabotage power conduits in the area. Graul's mission was to stop the Jedi Knight from disrupting Sadic's scheme. Graul, along with a number of Mark I Power Guards, fought the Hero, but the Jedi defeated them all. Following Graul's demise, the Hero found an encoded datapad on the Commander's corpse. The datapad contained information that revealed the location of an Imperial arms manufacturing plant situated in the Lower Industrial Sector, where the Power Guard initiative had been relocated.
