Darth Sion Darth Sion , the Lord of Pain , was a Sith Lord who lived in the time of the Old Sith Wars . As a Sith Marauder in the Great Sith War , Sion fought for Exar Kun ' s Sith Empire until the day he was struck down . Rather than die , though , Sion found that by calling on his pain , anger , and hatred , he could rise from certain death and achieve immortality , at the cost of all - consuming agony . With a body fractured and decomposing , but held together by the dark side of the Force , Sion survived the Great Sith War . Sion allied himself with the next Sith Empire to arise in the galaxy , that of Darth Revan and Darth Malak . Those Sith , too , fell , and he watched from the Sith Academy on Korriban as the Empire tore itself apart . Sion soon found new purpose with Darth Traya and Darth Nihilus , a pair of Sith Lords who together with Sion formed the Sith Triumvirate , dedicated to restoring the Sith and eliminating the Jedi . In their headquarters on Malachor V , Sion served as Traya ' s disciple . Eventually , frustrated with her teachings , he and Nihilus stripped her of the Force and cast her out . The two ruling Sith Lords went on to reunite most of the surviving Sith remnants and continue their war on the Jedi , with great success . With the Jedi all but eliminated , Sion took notice of a new Jedi returning to known space , the Jedi Knight Meetra Surik , who was exiled since the Mandalorian Wars . His attempt to kill her was thwarted by Traya , who managed to get Surik to Peragus II . Sion followed in a captured Republic ship , the " Harbinger " , but Surik and her companions escaped once more . He encountered her again at Korriban , but beginning to feel strange new feelings for her , he let her escape . Traya eventually betrayed Surik and returned to take command of the Sith and Sion . Sion awaited Surik on Malachor V ; in their final battle he was struck down again and again , but rose each time . Surik showed Sion the price he paid for immortality , convincing him to let go , and the Sith Lord at last allowed himself to die . Biography . Rise of a Sith Lord . The Human who would become Darth Sion lived in the time of the Old Sith Wars , around 4000 BBY . Sion — which may have been his given name — was for a long time susceptible to infirmity and pain much the same as any other person . Combined together , they were intolerable to him , and he lived a life steeped in hatred . Rather than suffer in silence , Sion chose to embody his pain as his uniqueness , becoming Darth Sion , Lord of Pain . In the Great Sith War of 3996 BBY , Sion served as a Sith Marauder in Exar Kun ' s Sith Empire . Seeking death , Sion went into battle against the Jedi but continued to survive the encounters . He became convinced he was immortal as he built up a greater and greater tolerance for pain . Eventually , Sion was struck down , but he did not die . Instead , the pain within him welled up to agonizing levels , driving Sion to rise once more and strike down his would - be killer with all his anger and hate . Sion found that he could hold his own decomposing body together with the dark side of the Force . Though this process brought him excruciating pain and forced him to continuously concentrate on his rage , Sion considered it a worthy price for immortality . Kun ultimately lost the war , but Sion survived the fall of Kun ' s Empire . In 3963 BBY , the Sith Acolyte Haazen prophesied that the Jedi Guardian Lucien Draay would teach Haazen ' s new Sith , suggesting " Darth Sion " as a possible name he could take ; Haazen was later defeated and Draay turned away from the path of the Lord of Pain . In time , the Mandalorian Wars fell across the galaxy as the clans of the Mandalorians invaded the Galactic Republic . Sion was shaped in these wars ; when they ended and a new Sith Empire was formed by Darth Revan , the new Dark Lord of the Sith , and his apprentice Darth Malak , Sion became a Sith Lord of the Empire . Yet this one was not to last either ; Sion was shocked , as Revan , redeemed by the Jedi Council , succumbed to what Sion saw as weakness and betrayed the Sith . Malak was killed by his old master and , with his death , the Empire came apart . Sion was at the Sith Academy on Korriban in its final days , and he watched as the Sith turned on each other . Sion survived this bout of backstabbing , though . With the disintegration of the Empire , a number of Sith Lords declared themselves to be warlords of their own domains , while other remnants fled for the Unknown Regions . The Sith Triumvirate . There were other Sith Lords at work in the galaxy with their own plans . One was Revan ' s former Jedi Master , Kreia , who had taken the name Darth Traya . Traya , searching for " wounds " in the Force , found Sion and another Sith Lord : Darth Nihilus , the Lord of Hunger . Sion , Traya , and Nihilus allied into the secretive Sith Triumvirate , based out of Malachor V , their goal was the annihilation of the Jedi Order and restoration of the Sith to power . Traya became the master of both Sith Lords , and Sion learned much from her . At Trayus Academy , a hidden Sith stronghold on Malachor V , Sion learned more of pain . There was discontent among the Triumvirate , though . Sion and Nihilus had ambition beyond that of Traya , and their fragile alliance , united solely by a hatred of the Jedi , grew strained . Sion , furthermore , grew tired of Traya ' s instruction , the abstractness of her teachings and the way her words seemed to echo in his skull . Eventually he and Nihilus conspired to remove her . While Traya meditated in the academy ' s core , Sion and Nihilus closed in on her . Sion beat her mercilessly , the two sapped her energy before Nihilus stripped her of the Force , and Traya was cast out . Now in sole command , Sion and Nihilus continued their work . Relying heavily on the Malachor - based Sith assassin s , originally founded by Revan , Sion went on a spree of Jedi assassination . He was killed a number of times over the course of it , but he continued to rise again and slaughter many Jedi in return . By the end of Sion ' s campaign , the Jedi were almost entirely extinct . In 3954 BBY , Sion and Nihilus united the majority of the Sith Empire remnants , becoming the most unified force of Sith in their time . In 3952 BBY Nihilus attacked a Jedi conclave on Katarr , killing many of the surviving Jedi . The Order publicly disbanded , the remaining Jedi going underground to escape Sion ' s assassins . Lonna Vash , a Master of the Jedi Council , came to Korriban in search of Sion , but she fell into a trap of his and was captured . Sion imprisoned Vash in the abandoned Sith Academy . The last of the Jedi . As the Jedi fell , one remained outside known space , a Knight named Meetra Surik who had been cast out of the Order and exiled for following Revan in the Mandalorian Wars . Atris , a surviving Jedi Master , sought to draw the Sith out of hiding , and so she arranged for Surik to return to the known galaxy , while at the same time leaking information of Surik ' s past . Rumor that Surik was the last of the Jedi was enough to draw the Sith out of hiding ; Sion studied her , where she had gone in her exile , and the battles she had fought in the war . When Surik returned from the Outer Rim , she had transportation secured for her aboard the Republic vessel " Harbinger " , and Sion and his assassins came after her in a Sith warship . But he was not the only one ; Kreia , now in possession of Revan ' s former ship , the " Ebon Hawk " , was also heading to recover Surik . Sion ' s warship intercepted the " Hawk " and opened fire on it , but the " Hawk " managed to send out a distress signal . The " Harbinger " picked up the signal and arrived to engage Sion . The warship , however , played dead , and the " Harbinger " connected an umbilical to it . The crew found Sion ' s body , and believing him to be a corpse , took him back to their vessel . Meanwhile , Sion ' s cloaked assassins infiltrated their way into the " Harbinger " . Sion was taken to the medical bay , where the medical officer studied him . Seeing the innumerable fractures and scars that covered him , she was unable to determine if he was alive or dead and placed him in a kolto tank . As this was taking place , Sion ' s assassins were moving throughout the ship , secretly eliminating some crew members and watching the others . Sion at last awoke and , after tormenting the mind of a passing crew member , burst from his kolto tank and announced that he had come for Surik . His assassins materialized around him , and they quickly killed the security team sent to medbay . Sion set off to find the rest of the crew . He would not get Surik , though . Kreia reached her first , took her aboard the " Hawk " , and escaped . Sion at last seized control of the ship , which due to the sabotage of one of its passengers was experiencing a system failure , and opened fire on the " Hawk " as it fled , hitting it as it leapt into hyperspace . Sion followed them to the mining world of Peragus II , controlling the " Harbinger " from a meditative pose on its bridge . He would not let those who had escaped him do so again without blood being shed . The " Harbinger " docked with the Peragus Mining Facility , and some of his assassins moved into the facility to watch their prey . Kreia , Surik , and Atton Rand , a prisoner they had found in the facility , came aboard the " Harbinger " in their search for an escape route , and Sion caught up with them in the vessel ' s stern . Brandishing a sword , Kreia moved to fight him as her companions fled . Sion was surprised she was still alive , and mocked her belief that a Jedi could stop the Sith from achieving dominion . Kreia , hiding , leapt out to attack , and Sion wheeled on her and cut off her hand . She escaped him and rejoined Surik and Rand aboard the " Ebon Hawk " , which proceeded to take off . Sion pursued in the " Harbinger " , and the ensuing firefight set off the volatile asteroids around Peragus , consuming the " Harbinger " in an explosion . Sion survived . Encounter on Korriban . Enraged that Kreia would sacrifice herself for Surik when she was so much weaker than himself , Sion grew determined to destroy all Kreia held dear , including Surik . He got his chance to catch her when she came to Korriban in search of Lonna Vash . Shortly after Surik arrived on Korriban , Sion killed the imprisoned Jedi Master . Within the hour , Surik had entered the ruins of the Sith Academy ; Sion sensed her arrival and had the doors to the Academy sealed behind her , as he sent his assassins in pursuit of her and her companions . Eventually Surik ' s party found Vash and unlocked the Academy entrance , but Sion moved to block their escape , at last coming face to face with her . Sion warned Surik that Kreia would in time destroy her , as he felt his former master had done to him . They fought , but even as Surik injured Sion , he called upon the Force to restore his health . Kreia at last called to Surik in the Force , telling her that it was not a battle she could win . Surik fled the Academy , and Sion , feeling a measure of respect for her , let her go , ordering his assassins not to harm her . He expected they would meet again . Sion soon began to feel a new emotion for Surik beyond respect or admiration , one that he could not tolerate . The Sith Lord found her beautiful , but he saw in these feelings weakness that would only lead to death . As she continued to dominate his thoughts , Sion grew to hate her for it . The final death . After Sion returned to Malachor V , he was soon joined on that world by Kreia , who had betrayed Surik , reclaimed her title of Darth Traya , and led Darth Nihilus to his death . After eliminating Sion ' s assassins , Traya found him in the Trayus Core . Sion threatened to kill her , but Traya , claiming that she had returned because she now understood Surik ' s choices , bent him to her will and made him prepare for the arrival of Surik . Traya commanded Sion that when Surik arrived at the Trayus Academy , he would show her every measure of respect . Eventually she came to Malachor in search of Kreia , and after fighting her way through the Sith forces of the academy , Surik at last came face to face with Sion . He cautioned her to leave , warning her that Traya would break her as she had Sion . Believing that Traya could not be defeated , Sion concluded that if Surik were to deny herself to Traya , Traya would have no choice but to accept Sion ' s loyalty again . He considered himself to have come further than any of her former apprentices , including Revan , and had decided that his initial betrayal was a test that he had passed . With words exhausted , Surik and Sion at last fought . Surik struck down Sion , but with the dark power of Malachor flowing through him , he rose again . Once more they fought , and once more he fell ; Surik tried to persuade Sion that Kreia did not respect him and was using him as a tool , but Sion claimed that if he killed Surik , Traya would have to complete his training as her true apprentice . As they continued their fight , Sion saw Surik ' s strength , but still believed himself capable of defeating her . As she struck him down a fourth time , Sion remained defiant . Surik told him that he had already been defeated , and she explained that Kreia had only respected those who could let go of the Force , not those like Sion who relied on it . Sion , who had not thought it possible to walk away from it , was forced by Surik ' s words to realize that the life of pain he had given himself was ultimately one of permanent weakness and dependence instead of power . In his last moments , Sion warned Surik that Traya would break her , and he told her that she was Traya ' s weakness , just as she had been his . Finally at peace , and glad to leave the living world behind him at last , Sion allowed himself to die . Legacy . Long after Sion ' s death , a faction emerged among the Baran Do — an order of Force - sensitive Kel Dor from the planet Dorin — that sought to become Sith . The cultists left offerings to the deceased Sion in a Baran Do monastery and by 3640 BBY , during the Cold War , the offerings bequeathed to the Sith Lord were recovered by an individual . Personality and traits . From his very beginning , Darth Sion filled himself with hatred , ultimately giving him the power to overcome death . He chose to embody his pain rather than tolerate it as a normal part of existence , turning it into something far greater . Sion fed upon his pain for sustenance , and he sought to spread it to all Jedi across the galaxy . As the Force gave him his power , Sion felt it called on him to continue to fight ; the Force was all he was , and the dark side was his identity . And yet , Sion also had a desire to heal ; the galaxy , he felt , was fractured , and he could not understand those who had the power to fix it and did not , like Revan . Sion was tenacious ; when he cornered his prey on Peragus II , the Sith Lord would not let them go without bloodshed . He was cunning ; though Jedi Master Lonna Vash considered him volatile and thought him an easily - influenced brute , Sion would ultimately trap and kill her . Ambitious and power - hungry as well , Sion would not forever bend to the will of his Sith Master , Darth Traya , and he and Darth Nihilus eventually turned on her , using Nihilus ' special techniques in the Force to tear down her defenses and then beating her mercilessly . Sion and Nihilus differed from prior Sith in that the death of the Jedi Order was their sole objective ; the manner in which they fought the Jedi differed too , lying in hiding and striking from darkness . While Sion immersed himself in hate , he was still able to feel positive emotions , such as love and compassion , which he felt toward Surik . He came to feel her as beautiful , a feeling that reduced his hatred , and thus endangered his life . In the end , Surik persuaded Sion to let go of his hate and the Force , and accept death . Injuries . In his years as a Sith Marauder , Sion regularly fought on the front lines of the Great Sith War , and in surviving , he built up a tolerance to pain . When at last he achieved his method of immortality , every centimeter of Sion ' s body crawled with agony . Sion ' s flesh was decomposing , covered in cracks and scars , and his body existed in a state of undeath . His skeleton was fractured in thousands of places , as every bone in his body had been splintered repeatedly and then reassembled . The Force was all that held him together . Personal relationships . Kreia and Surik were in many ways alike to Sion , yet different , he felt , in the important ways . Both constantly lingered in his mind , but whereas Kreia would fill his thoughts with her views and teachings , Surik was merely a presence in his head . The two were constantly tied in his life ; Kreia ' s weakness was Surik , and in saving the latter he sought to influence the former . Kreia . Though Sion learned much from Kreia , he thought of her as a shrew and became frustrated with the abstractness of her teachings . He believed her teachings to weaken the Sith , ultimately leading him to overthrow her , and saw it as a failure of hers that she could be defeated so . He considered himself , not her , to be the master . Sion thought that she had destroyed him , and in turn sought to kill her and make her watch all she had built and all she held dear be destroyed with her . When she eventually returned to Malachor and sought his allegiance , though , Sion succumbed to her will . As much as he wanted Surik to save herself , Sion also believed that in her leaving , Kreia would have no choice but to accept his loyalty . All that was left for him , by the time of his death , was his master . Kreia , in turn , believed that Sion ' s power had blinded him . She considered it his great failing that he had fallen without learning anything , and criticized him for his lack of knowledge . Kreia respected turning away from power , giving up the Force ; Sion , she felt , was a slave to it , and she did not respect him for it . She believed his continued existence was a threat to life itself . Even after returning him to her service , Kreia merely used Sion to test Surik , though Sion believed her to be pitting the two against each other to see which would be her apprentice . Meetra Surik . When he first set after her , Sion thought Surik to be broken and incapable of stopping the onslaught of the Sith . Her death , as what he believed to be the last of the Jedi , would herald the victory of the Sith . As he continued to pursue her , though , a new feeling towards her stirred in Sion , something beyond respect or admiration , and an emotion that he loathed . He thought her beautiful , and his hatred diminished with these emotions , threatening his grip on life . Sion immersed himself in the life of Surik , studying her history . Believing that Kreia would try to destroy her , Sion offered to end her life himself . He grew angry and jealous , knowing that even though she had not yet survived Kreia ' s teaching and defeated the old woman as he had , Kreia would still give her life to save Surik . He thought of her as a being of weakness and fear , unfit to be Kreia ' s apprentice . Yet , when she bested him in combat , he let her go , believing she had earned it and knowing they would meet again . Kreia commanded that Sion show Surik every respect when they next met , on Malachor . He offered her mercy , in his way : that she die on the surface of Malachor , and not by the suffering of Kreia . Yet Surik at last convinced him to let go , and in his last words he warned her of Kreia ' s goals for her . Powers and abilities . Sion was at Revan ' s Sith Academy on Korriban , and later learned of the ways of pain at Trayus Academy on Malachor V . With the dark side , he could hold together his decaying body . Though excruciatingly painful , and requiring endless concentration on the anger within him , it gave him his powers of immortality . When struck down , Sion could call upon his anger , hate , and pain to come alive again . In places strong in the dark side , like Korriban and Malachor V , the Force flowing through Sion made him nigh - undefeatable . Jedi Master Lonna Vash considered him " a perversion of the dark side . " Sion needed hatred to hold onto his power ; he grew threatened when his feelings for Surik seemed to diminish this and erode his ability to hold onto life . Ultimately , she would convince him to give up his hatred and , in doing so , submit to death . The Sith Lord was glad when he could finally lay down his life . Sion had a number of Force powers at his disposal : Telekinesis ranging from Force Whirlwind to Force Wound , Force Slow , Force rage , Force Immunity , and Force drain . He was immune the effects of fear - based Force attacks . Behind the scenes . Darth Sion is one of the main villains of 2004 ' s " " , voiced by Louis Mellis . Sion was first revealed on July 14 , 2004 , at LucasArts ' Summer Press Day 2004 , in an in - game demonstration of the character on the " Harbinger " . Leland Chee has stated that Sion ' s name comes from the word " scion , " meaning " heir . " While concept art for a fight between Sion and Atris was produced , no such event occurs in the game . Sion was featured prominently in the " Knights of the Old Republic II " cover , and the game ' s score , by Mark Griskey , includes an individual theme for the character . In 2008 , Sion appeared in a Dark Horse for the " Knights of the Old Republic " miniatures pack ; in it , he is a lackey of Mandalore the Ultimate , fighting Zayne Carrick . Downloadable content for the 2008 video game " " also included Sion as a player model ; the character ' s rendition here differs from the " Knights of the Old Republic " version in some details , including a shoulder pad and several bolts through Sion ' s chest . In 2013 , Sion ' s shinguards , vambrace , leggings , and sash were added to " " as player armor . In the game , Sion ' s interactions with Meetra Surik differ based on whether Surik is male or female ; while he is jealous and hateful of a male Surik , the game programming notes describe him as feeling love towards a female Surik , though he is unable to express it as such . Chris Avellone , lead designer of " The Sith Lords " , has stated that of the plots in the game he would like to see explored further in the Expanded Universe , Sion ' s relationship with the female Surik is among them . Cut content . A number of scenes featuring Sion were cut from the final release of " Knights of the Old Republic II " . The dialogue files and many other parts of these scenes still exist in the game files , and so most of them have been reconstructed . Conflict with Nihilus . An earlier version of the Nar Shaddaa portion of the game had a subplot with the GenoHaradan , ultimately replaced by one with Visquis and the Exchange . Sion first appeared in this plot on Malachor V , meditating over a hologram of Meetra Surik . A Sith assassin reported to him that Surik had survived , and Sion ordered his ship prepared so he could travel to Nar Shaddaa himself . When Surik infiltrated the GenoHaradan base , a trap caused it to explode , seemingly killing her . Believing Surik to be dead , Sion returned to Darth Nihilus on the " Ravager " . There , he gloated that he had killed Surik and informed Nihilus that Traya had survived , then dissolved their alliance . As Sion walked away , Nihilus attacked him , blasting him backwards and starting a fight between them . A video reconstruction of this scene has been created by fans . Vash and Kaah . At one point , Lonna Vash was alive when Meetra Surik came to Korriban . Surik convinced her to come to Dantooine to speak with the Jedi Council , but they were attacked by Sion as they left the Academy . Vash closed the door out and sacrificed herself to Sion , allowing Surik to escape . Other files in the game indicate that Vash ' s Padawan Kaah Ohtok , entirely cut from the game , fled after Vash was captured by Sion . Kaah and Vash knew there was a Sith Lord on Korriban before visiting , but were unprepared for how powerful he was ; after encountering him , Kaah described Sion as an " assembly of broken bones , the ultimate killing machine of the Dark Side . " Having captured Vash , Sion ' s Sith intended to sacrifice her in a ritual . On Malachor V . When Kreia returns to Malachor V and bids Sion to join her again , a short scene was cut expanding on his reasons . After Sion threatens that he will not spare Kreia again , she informed him that he simply did not learn her lesson , that his strength was meaningless . She then lifted him in the air and crushed his body with the Force . Another scene , set to play when Surik lands on Malachor , showed Sion informing Kreia that she had arrived . Kreia ordered the Exile to be brought before her , and Sion grew concerned about what Kreia would do to her . Kreia mocked him on the fact that he might still have emotions within him , and then informed Sion that she would break Surik . In the male Surik version of this , Sion is not concerned , but is now angry that Kreia intends to use Surik as a vessel for her teachings . A third path in this dialogue has Kreia order him to do nothing . Sion and Atton . In the game ' s ending on Malachor V , Meetra Surik ' s companions were originally to confront Kreia . After she defeated them in battle , they were all taken into captivity with the exception of Atton Rand , who escaped . Sion was sent to pursue Atton through the halls of the Trayus Academy . Eventually they fought , with the player controlling Atton . If Atton was defeated , Sion cut off his arm and left him lying on the ground . Atton got to his feet once more and postured at him , but Sion lifted him from the ground and vowed to mutilate Atton into a mirror of the Dark Lord himself . Atton told him to " take his time , " and a gleeful Sion obliged .
