Arber was a male Human lieutenant in the service of the Imperial Remnant during the Yuuzhan Vong War. At the Battle of Borosk, Lieutenant Arber was in charge of the gravitic amplitude modulator fitted to the Star Destroyer Defiant, a device capable of jamming yammosk war-coordinating signals. He was successful in using the GAM against one yammosk, helping lead the Defiant to that warship-analog's destruction.
