Rosh Penin Rosh Penin was a Human male Jedi student at the Jedi Praxeum located on Yavin 4 , after the fall of the Galactic Empire , where he was trained in the ways of the Force by Jedi Master Kyle Katarn . Biography . Jedi apprentice . In 14 ABY , Penin , along with other Jedi students , was heading to the Jedi Praxeum on Yavin 4 onboard a shuttle . In the ship , he met Jaden Korr , and the two eventually developed a friendship . Their shuttle was soon attacked by the Disciples of Ragnos and forced to crash - land , though the attack later proved to be merely a diversion so that the cultists could access Luke Skywalker ' s personal records in the Massassi temple . After recovering from the shuttle crash , Penin and Korr teamed up in order to reach the temple . They fought hostile howler s in the rainforest : Penin was shooting with a blaster pistol while Korr was using his lightsaber . After witnessing stormtroopers patrolling the perimeter of the Temple , Korr went on ahead alone and quickly dispatched them , along with a Sith Cultist but was then knocked unconscious with the Scepter of Ragnos by Tavion Axmis . Penin then went for help and brought Luke Skywalker and Kyle Katarn back with him , but the Disciples of Ragnos ' forces were already gone . Penin and Korr soon were both assigned Katarn as their Master and began Jedi training . During their very first training exercise , Rosh set a lightsaber training droid to attack Jaden in order to distract him and finish the training course first . His plan succeeded and Jaden fell behind , but , at end of the course , Katarn chastised Penin , saying the droid would have killed Korr had it been set to Luke ' s training regimen . Penin apologized to his fellow student , an apology which Korr accepted . Fall to the Dark Side . Penin often felt that Katarn was holding him back , and as a result grew arrogant and impatient . Eventually , Penin was assigned to investigate Byss , where he was captured by the Disciples of Ragnos . At first , he was afraid he would be killed , but instead of killing him , they took advantage of his fear to convert him to the dark side . Penin ' s naiveté and lust for power made it easy for the Cult to turn him , and he became an apprentice to Axmis , leader of the Disciples of Ragnos . On Vjun , Penin , Axmis , and the Kothos twins led the Cult ' s operations in Bast Castle in order to siphon the Force energies that were stored there . Katarn and Korr arrived on Vjun , intent on stopping the cultists , but were separated . Korr later located and confronted Penin in Vader ' s throne room , where Penin , with the aid of the twins , dueled Korr . Penin and Korr were evenly matched until Korr managed to kill the twins . He soon after disarmed Penin just as Katarn arrived . Before they were able to apprehend Penin , Axmis intervened . She disabled Katarn and Korr with Force lightning , and afterward revealed that she had taken Penin as her new apprentice . Axmis ripped Korr ' s lightsaber from him with the Force , threw it at the ceiling and brought the weakened structure down on the Jedi with the Scepter of Ragnos . She then used the ensuing chaos to escape with Penin in tow . Katarn used the Force to prevent the ceiling from crashing down on top of them while Korr used Katarn ' s lightsaber to create an exit . Redemption on Taspir III . Some time later , Penin repented and tried to turn away from the dark side while on Taspir III with Alora , Tavion ' s other apprentice . He sent a distress signal to the Jedi Praxeum . Katarn and Korr arrived on Taspir III and began searching for Penin . Korr eventually located Penin , who begged for forgiveness for attacking Korr on Vjun , and admitted that his fear was what made him fall to the dark side . As Penin did not appear to need any obvious assistance , Korr ' s anger at Penin revealed itself once again , and he came close to striking down his friend . Katarn communicated with Korr through the Force and pleaded with Korr to deactivate his lightsaber . Korr relented , though Alora , who had been watching from a distance , then attacked the pair . As one of her opening attacks , Alora severed Penin ' s entire left arm due to his disloyalty , after which Korr struck her down in battle . Katarn arrived soon after , which proved to be timely as Penin went into shock , and his Master rushed him back to the Praxeum for treatment . While there , Penin tested his new prosthetic left arm which looked identical to his original severed arm , and was greeted by Luke Skywalker , who expressed hope that Penin ' s experience with the dark side had taught him the patience and humility that one day would turn him into a great Jedi . Penin gratefully accepted the Jedi Master ' s words of encouragement . Lightsaber . Penin possessed a yellow - bladed lightsaber as a Jedi . When he turned to the dark side , he used a red - bladed lightsaber . Personality and traits . Prior to joining the Jedi Praxeum , Rosh Penin was enthusiastic about becoming a Jedi , but grew arrogant and impatient during his training under Kyle Katarn . He came to believe that Katarn was holding him back from reaching his full potential and did not appreciate his talents . For a time , Penin saw his friend Jaden Korr as a rival and would try to best him during their lessons . He turned to the dark side out of fear for his life when confronted by the Disciples of Ragnos , and embraced the power of the dark side , but eventually realized his mistake and returned to the light . He was accepted back into the Academy and heeded Luke Skywalker ' s advice about patience and humility . Rosh , while primarily good natured , was flawed in how overconfident he was in his abilities and proved to be something of a coward as he was easily swayed to join with a cult for fear of being hurt . Powers and abilities . As a Padawan , Penin was a capable lightsaber duelist and mastered the majority of his core abilities , including Force protection , Force absorb , Force drain and Force rage . He was also efficient at using Force lightning and Force grip , and utilized both these Force powers against Jaden Korr during their confrontation on Vjun after Penin ' s fall to the dark side . Behind the scenes . Rosh Penin was voiced by Jason Marsden in " " . At the beginning of the game , Rosh wields a yellow - bladed training lightsaber ; after he turned to the dark side , he was given a red - bladed lightsaber by Tavion Axmis . Examining the game ' s external source files , it ' s notable that Rosh obtains a shadowtrooper ' s lightsaber , rather than that of a New Reborn . This , however , does not change anything in terms of his lightsaber ' s appearance , as both of the mentioned sabers use the same hilt design . When fighting Rosh in Darth Vader ' s stronghold it ' s impossible to kill him , as the two reborn that accompany him will restore him once his health drops low enough . Despite this it ' s possible to cut off his hand in combat , if this is done Rosh will continue to attack as he did before as his A . I . doesn ' t realize that his lightsaber is no longer there . Alternate ending . " The following is from the non - canonical ending of the game . " After Jaden found Rosh on Taspir III , Jaden gave into his hatred and anger , and decided to kill Rosh . Rosh begged Jaden to let go of his anger before he attacks him . Jaden ignored his request and plunged a lightsaber through his torso , mortally wounding him . Jaden then killed Alora and fled to Korriban . Kyle arrived just as Rosh was dying and told him that in turning back to the light , he became a full Jedi .
