darth malgus (veradun) was a male human dark lord of the sith and apprentice to vindican, who served the sith empire during the great galactic war against the republic. following the successful recapture of korriban from the jedi, malgus killed his master and later led a surprise assault on alderaan, only to be defeated by his nemesis and former opponent from korriban, satele shan. malgus was severely injured in the fight against shan, forcing him to worn a respiratory apparatus for the rest of his life. some time later, malgus was tasked by his superior, darth angral, with leading an assault team on the jedi temple on coruscant, which malgus and his forces successfully destroyed, disgracing the jedi order in the eyes of the republic. although malgus believed that the battle of coruscant was the first step of destroying the republic, it only served as leverage in the peace negotiations that took place on alderaan. while the alderaanian summit progressed, the sith settled into an occupation of coruscant. malgus was placed in charge of orbital security, but the sith lord defied his orders and traveled back to coruscant's surface to strike against the renegade jedi aryn leneer, who wanted to avenge her master ven zallow, whom malgus killed during the attack on the jedi temple. although leneer ultimately failed, the conflict caused malgus to become disillusioned with the empire and to kill his lover eleena daru, seeing their relationship as a weakness that prevented him from preserving his own power, which he later used to cleanse the empire of the politicians whom he blamed for allowing the republic to survive. during the cold war years that followed the successful peace negotiations, malgus led sith forces into the unknown regions, claiming previously-unknown territories for the empire. towards the end of the war, following the presumed death of the sith emperor and after serving on the dark council, malgus declared his own empire, free of the infighting of the dark council. however, the republic and the sith empire forces soon teamed up to fight against malgus' empire and managed to track him down to his secret base he was tracked down to his secret base, where he was defeated. despite his presumed death, malgus later resurfaced during the invasion of ossus at the start of the third galactic war, once again serving as a commander withing the sith empire. thousands of years after his death, malgus was still remembered as one of the most powerful sith lords to have ever lived, with darth sidious even retrieving some surviving excerpts of malgus's journals from an antiquities dealer and bounding them into his "book of sith", an anthology of sith historical writings.
