Balthazar Gallo was an Imperial Knight who went on an odyssey shortly before the Sith Insurrection. He was captured and imprisoned by Addipos the Hutt at a coliseum until he with fellow prisoner Athos rebelled. Afterwards, Balthazar took on the role of Knight-Commander, a title empty since the death of Ayumi Pallopides at HOMEFRONT. However, after reunifying some of the scattered Imperial Knights and recruiting new ones, such as K, he left the Imperial Knights in the hands of Athos.
