In the climactic battle of the Shu-Torun conflict, Trios, the monarch, commanded her devoted troops in an assault targeting Rubix's delving citadel, the stronghold of Rubix, the ore-dukes' leader who was in revolt against her reign. Midway through the conflict, Darth Vader, the Sith Lord commanding the Galactic Empire's legions, entered the battle alongside Trios, swiftly securing the triumph. Following Rubix's capitulation, Trios put him to death and appointed Bixene, his offspring, to inherit his title.
