Starkiller ' s Trial of the Spirit Starkiller ' s Trial of the Spirit occurred in 2 BBY during his final visit to the Jedi Temple on Coruscant . Shortly after Starkiller rescued General Rahm Kota on Cloud City , he felt as though the Force had urged him to return to the fallen headquarters of the Jedi Order . Hence , he traveled back to the capital world of the Galactic Empire once more in order to discover why he felt drawn to the Temple . Upon his return , however , Starkiller found the Jedi Temple guarded by many stormtroopers and several variations . Despite being overwhelmingly outnumbered , the apprentice single - handedly killed numerous Imperials as he infiltrated the ruins of the Temple . When he reached the chamber of the former Jedi High Council , he witnessed a Force - induced vision of his master , the Sith Lord Darth Vader , engaged in combat with a Jedi unknown to him . But just as Starkiller defeated the Jedi in defense of Vader , he realized that it was a vision of his dead father . Out of a desire to learn more about the father he had all but forgotten during his tutelage under Vader , Starkiller made his way to the Tower of First Knowledge where he hoped to discover more information about Kento Marek . After he fought his way past various Imperial soldiers that blocked his way , he came across a holocron that contained a gatekeeper in the person of his father . Starkiller then experienced a new vision , in which he was confronted by his own darkness ; a manifest form of the Dark Lord he could become . After a lengthy and hard - fought duel , Starkiller ultimately passed his final trial when he slew the Sith specter . But just as he regained consciousness , the Sith apparition warned Starkiller that there was no escape from the dark side of the Force . History . Return to the Jedi Temple . Like Starkiller ' s previous missions to the Jedi Temple on Coruscant , the secret apprentice encountered an Imperial security force of stormtroopers , scout troopers and several other variations , plus Imperial Senate Sentinel s and Imperial Navy commando s . Although the garrison had been reinforced with more soldiers due to his prior visits , including attempting to kill Starkiller on the spot as soon as he arrived instead of simply attempting to detain him like before , the Imperials ' efforts to execute the apprentice were ultimately ineffective ; Starkiller made his way deep into the Temple while dispatching many troopers . After Starkiller discovered an elevator platform , he utilized it and ascended to the top of the High Council Tower . Upon entering the damaged room of what once served as the chamber of the Jedi Council , Starkiller witnessed a duel between a simulacrum of his master Darth Vader and Kento Marek , a former Jedi Knight who had long since been dead . At the time , Starkiller was unaware of the nature of the fight and the Jedi ' s identity . As Marek stood triumphant and prepared to strike Vader down , Starkiller immediately moved to his master ' s defense . Father versus Son . The simulacrum of Kento Marek attempted to avoid a fight with Darth Vader ' s personal assassin and urged him to reconsider his allegiance to the dark side of the Force . Yet his efforts to reason with the young Sith were to no avail ; Starkiller had no interest in relinquishing the dark side for he felt that it was all he ever had in his life . At first , Marek fought effectively through the use of his skills in lightsaber combat , as well as telekinesis . Ultimately , however , Marek failed to overcome the apprentice ' s raw power in the Force . Though Marek evasively moved from one corner to another throughout the chamber , he was eventually intercepted by Starkiller , who proceeded to telekinetically thrash the Jedi all over the room . As Marek attempted to regain his footing , Starkiller sprang forward and stabbed him through the abdomen . Marek fell to his knees in defeat and his simulacrum vanished , but not before he apologized for the life that had befallen Starkiller , whom he referred to as his " son . " Starkiller was shocked at the revelation that the simulacrum of the unknown Jedi had actually been his dead father . But as he reached out to his father , the simulacrum vanished , leaving him alone within the ruins of the High Council Chamber . The rediscovery of Kento Marek had a strong effect on Starkiller , who then chose to search the Temple in order to learn more about his father . The Tower of First Knowledge . After the incident in the High Council Chamber , Starkiller returned to the " Rogue Shadow " , only to use it as a transport to reach the Tower of First Knowledge . The holodroid PROXY warned him that the tower possessed a large presence of Imperial soldiers , but Starkiller was too concerned with rediscovering his origins to be deterred at this point . Hence , he dropped from the " Rogue Shadow " and landed on the surface of a platform that connected to the tower . As several stormtroopers were thrown back in all directions due to the force of the impact , the apprentice ignited his lightsaber and steadily wiped out the remaining Imperials that challenged him . Even the stormtrooper commanders and their Shadow Trooper s were incapable at subduing Starkiller . When the platform had been cleared , Starkiller proceeded into the tower while General Rahm Kota used his intimate knowledge of the Temple ' s inner workings to act as the apprentice ' s guide through a comm channel . Inside the atrium of the tower , Starkiller was attacked by a combination of shadow troopers and Imperial jumptroopers . As he overcame the numerous soldiers stationed throughout the tower , including several Jedi training droids that remained dormant but active since the of the Jedi Temple , the apprentice used the Force to adjust a shattered bridge that stretched across the central chasm and led to the Holocron Chamber . When he accessed one of the holocrons inside the chamber , a gatekeeper appeared in the form of his father . Although Kento Marek asserted that Starkiller was ultimately the only one who controlled his own fate , he did concede that the dark side of the Force had grown strong within his son . Nevertheless , he assured Starkiller that redemption could still be obtained . After the simulacrum of Marek reminded the apprentice of his inherent potential and blood relation to a Jedi , he implored Starkiller to complete the Jedi Trials . At that moment , Starkiller slipped into the state of another vision created by the Force . Starkiller faces himself . Trapped within a labyrinth of his own mind , Starkiller was forced to navigate his way through the area . At the same time , he utilized his skills in telekinesis to overcome the obstacles of the trial . Once the tests of his Force abilities had been completed , Starkiller turned to find the final challenge behind him . Out of the shadows emerged the physical incarnation of the apprentice ' s inner darkness , clad in sinister armor painfully grafted to its wearer ' s body . Unknown to Starkiller , the dark specter ' s appearance was attributed to a possible future where he succeeded Darth Vader as Darth Sidious ' apprentice . As Starkiller and his dark self fought each other in a vicious and brutal fight , during which both relied on lightsaber combat skills and dark side techniques , Starkiller managed to hit the Dark Lord , which caused his helmet to fall off . Before Starkiller could press his attack , however , he froze in shock of his opponent ' s face ; it was his own , except pale skinned and twisted in features as a result of deep immersion within the dark side of the Force . While Starkiller paused at the sight of his own visage , his loss of focus was swiftly capitalized on by the Dark Lord , who drove the apprentice down to a lower level within the labyrinth . Starkiller regained his footing after a moment , just as his " other self " began hurling large pieces of debris at him through the Force . Starkiller managed to survive the attacks by evading and redirecting the objects back at the Dark Lord . They soon resumed their duel , which only grew in ferocity due to the renewed vigor on both sides , until Starkiller forced his opponent to the brink of the platform . However , the Dark Lord stopped his fall when he grabbed hold of Starkiller ' s ankle , whom he pulled down in order to haul himself back onto the platform . Having captured the high ground , the Dark Lord telekinetically took control of several massive columns and hurled them at Starkiller , who countered the attack by using them as stepping stones to climb back up . As he ascended to equal footing with the Dark Lord , Starkiller impaled him from behind with a lightsaber blade through the back . With his final challenge completed , the vision came to an end as the apprentice ' s " darker half " became consumed in a bright light of Force energy . However , as Starkiller regained consciousness inside the Holocron Chamber , the vision had not completely ended . Just as he regained his senses , Starkiller ' s attention turned to his left hand , which had taken on the clawed and emaciated appearance of the Dark Lord ' s arm . After a final warning about how Starkiller would never truly escape the darkness that resided within himself , the vision came to a complete end . Starkiller was shaken by the revelation of his " other self , " and when Rahm Kota inquired about the apprentice ' s discovery , he neglected to reveal any of the details of what transpired in his vision .
