Duel at the Czerka mining facility During the Desolator crisis of 3643 BBY , the Sith Valis lured the Jedi Padawan Kira Carsen and her master to an abandoned mining facility in the Outer Rim , forcing a duel between them . Valis was a Child of the Emperor — an agent of the Sith Emperor ' s will — and , on the orders of his " father , " sought to bring the former Child Carsen back into the fold . Believing that they were meeting Admiral Hacklin of the Sith Empire to negotiate his defection , Carsen and her Jedi Knight teacher traveled to the station , but instead found Valis , and he was killed in the fight that followed . As a result of the duel , Carsen revealed her past to both her master and the Jedi Council , giving the Jedi Order concrete evidence about the existence of the Children . Prelude . Kira Carsen was born on the planet Dromund Kaas , the capital of the Sith Empire , and given as an infant to the Sith Academy on the planet Korriban . As a child , she was selected by the Sith Emperor to become one of his Children — agents of his will who unknowingly served as his eyes and ears throughout the galaxy . However , Carsen fled the Empire before the process could be completed , leaving behind her fellow Children such as Valis and Suri . She made her way to the moon of Nar Shaddaa and lived on the streets before becoming a member of the Jedi Order , though she hid her past and her Imperial heritage out of fear of being kicked out . Around 3643 BBY , the Sith Lord Darth Angral declared war on the Galactic Republic and the Jedi Order in response to his son Tarnis ' s death at the hands of Carsen and a young Jedi Knight . Angral seized control of several Republic superweapons , prompting the Jedi Knight and Carsen to pursue Angral ' s agents across the galaxy , and the Knight took on Carsen as a Padawan , as Carsen ' s previous Master Bela Kiwiiks was on her own assignment . While the Knight was on a mission to the surface of Ord Mantell , Carsen remained behind on the Ord Mantell Orbital Station , where an Imperial operative identified her as the Knight ' s apprentice and contacted Darth Angral . Angral and his retainers , including Admiral Hacklin of the Imperial Navy , arrived and interrogated Carsen as to the Knight ' s whereabouts , though Carsen tricked the Sith Lord into heading to the planet Corellia . Though Carsen escaped Angral ' s servants with the help of her teacher , Angral recognized her as a former Child , and the knowledge of her survival reached the Emperor . The duel . Determined to recapture Carsen , the Emperor dispatched his Child Valis to bring her back to him . Posing as Admiral Hacklin , Valis contacted the Republic and claimed that he wanted to defect — but would only do so to Carsen and her master . General Var Suthra arranged for a meeting between " Hacklin " and the two Jedi at an abandoned mining facility formerly operated by Czerka Corporation in the Unknown Regions . Valis arrived before the Jedi , and he departed his ship and hid among the cargo crates within the facility ' s hangar . When the two Jedi arrived , he watched them approach his ship before stepping out into the light and speaking to them . After introducing himself and thanking the pair for coming , Valis apologized for the deception , but Carsen immediately recognized him and warned her Master to attack . Amused , Valis explained that Carsen was of the Empire and a Child of the Emperor like him , and that their father desired his wayward Child returned to him . The Knight refused Valis ' s request that the Jedi allow him to take Carsen home , and the Padawan charged the Sith and brought her double - bladed lightsaber down upon his head — only for Valis to summon his own lightsaber to his hands and block the attack before telekinetically blasting her backwards . The Knight rushed to Carsen ' s defense , and battle was joined between the three combatants . Despite Valis ' s combat prowess and skill with both telekinesis and Force lightning , the Child was ultimately no match for the combined strength of Carsen and the Jedi Knight , and he was slain . Aftermath . Once the two Jedi returned to their ship , Carsen revealed her past to her teacher , and the Knight and Carsen revealed her past to the Jedi High Council as well . Despite Master Jaric Kaedan ' s desire to banish her from the Jedi Order , Grand Master Satele Shan gave her blessing for Carsen to continue as the Knight ' s apprentice , though General Suthra was wary of her involvement in further operations . When the conflict with Angral came to a head in a battle over the planet Tython , Angral was slain by the Knight , but the Emperor reached out to his former Child and took complete possession of her . However , with her teacher ' s help , Carsen was able to drive out the Emperor and sever the link between them . Behind the scenes . The duel with Valis first appeared in the Jedi Knight class mission " The Defector " in " " , a video game released in 2011 . The mission serves as the intermission of the Act I story , bridging the class storylines on the moon Nar Shaddaa and the planet Tatooine .
