Cassius Madine
Cassius Madine, a Human male commander, served in the Galactic Republic's military. He engaged in combat with the reconstituted Sith Empire throughout both the Cold War and the Galactic War.
Madine found himself posted on Balmorra in 3642 BBY, where he was tasked with supporting the local resistance against the Sith Empire. It was during this period that his fixation on the superweapon called the Barrager began, as he was convinced that it held the key to the Republic averting a repeat of the Sacking of Coruscant.
