Biography . Born sometime during the Great Galactic War between the Galactic Republic and the Sith Empire , the Human male Valis was taken from his parents as an infant and sent to the planet Korriban , where he was inducted into the Sith Academy . Alongside fellow recruits such as Kira Carsen , Suri , and Tannac , Valis underwent training in the use of the dark side of the Force , and he was taken to see the Sith Emperor on several occasions . By the time he was a teenager , Valis had become a Child of the Emperor , an extension of the Emperor ' s will , and was imbued with a portion of the Sith ruler ' s power . However , in 3653 BBY , his fellow Child Carsen escaped from Korriban , as she feared what the Emperor was doing to her mind , and she later joined the Jedi Order . In 3643 BBY , the Emperor was alerted to Carsen ' s continued existence when the former Child was captured by the Sith Lord Darth Angral aboard the Ord Mantell Orbital Station . Carsen escaped her captors with the help of her Master , the former apprentice of Jedi Master Orgus Din , but the Emperor ordered Valis to bring Carsen back to him . Posing as the Imperial Admiral Hacklin , Valis contacted General Var Suthra of the Republic Military and claimed that he wanted to defect — but that he would only do so if he could meet with Carsen , whom Hacklin had met when the girl had been captured by Angral . Valis then took a starship to an asteroid mining facility in the Unknown Regions , the meeting place that Suthra had selected for the defection . Valis disembarked his ship and hid behind several cargo crates in the hangar , watching as Carsen and her Jedi Knight teacher arrived in their ship . When the two Jedi reached his ship , Valis stepped out from his hiding place and greeted the pair . Introducing himself and apologizing for using Hacklin ' s name in his deception , the Sith was recognized by Carsen , and he was amused at how his sibling immediately warned her Master to attack . Valis then informed the Knight of Carsen ' s true past , warning the former Child that the Emperor wanted her back , and asked her Master to peacefully leave him to settle the matter with Carsen . However , the Knight refused , and Carsen rushed her " sibling " to attack him with her double - bladed lightsaber . Valis drew his own lightsaber to his hand and ignited the purple blade in time to block Carsen ' s strike before throwing her backward with the Force . Carsen ' s Master then joined her in battling Valis , and the Sith unleashed arcs of violet Force lightning at his opponents as the three dueled back and forth across the hangar . Despite his strength in the Force , however , Valis was unable to overcome the combined strength of Carsen and the Knight , and their duel ended when Valis was struck down by the Jedi . Personality and traits . Fair - haired and fair - skinned with brown eyes , Valis was arrogant and confident in his superior strength and power . Despite this , Valis was cultured and polite , and he was perfectly willing to allow the Knight to leave if the Jedi allowed him to take Carsen peacefully — but he would not back down from his mission to retrieve the wayward Child at any costs . Valis took great pride in his status as a Child of the Emperor , and he truly considered the Emperor to be his father . Powers and abilities . Trained at the Sith Academy , Valis was strong in the Force and skilled in the use of the dark side . He freely utilized offensive Force powers in combat , making use of telekinesis to throw his opponents across the battlefield as well as energy blasts and Force lightning during his battle with Carsen and the Knight .
