Sergus Lanox was a male Human who served as a captain in the Imperial Navy during the Galactic Civil War. He commanded the Victory-class Star Destroyer Imperial Hazard, and his abilities gained him the respect of both his crew and other officers within the Fleet. Lanox still held the rank of captain in 11 ABY, when Byss, the throneworld of the reborn Palpatine, was destroyed. When word of the event reached Lanox, he became convinced that the Empire was doomed.
