Battle of Korriban (Galactic War)

During the Galactic War, Arcann and Thexan, the twin princes of the Eternal Empire, led an assault on the Sith holy planet of Korriban, where the Twi'lek female Sith Darth Atroxa coordinated the defending forces. Arcann suffered grievous injuries in the fight, including the loss of his left arm, and Thexan comforted him while he had a prosthetic limb attached. Shortly thereafter, Arcann used his newly augmented strength to kill several Sith warriors and Darth Atroxa herself, after which the brothers boarded a shuttle and left the planet.
