Sith Triumvirate The Sith Triumvirate was a loose alliance of what remained of Darth Revan ' s Sith Empire that almost destroyed the Jedi Order during the era of strife that took place after the Jedi Civil War . It was solidified sometime after the Battle of Rakata Prime . This organization was made up of several , if not hundreds of Sith apprentices , Sith Masters , and , most importantly , Sith assassin s . It was responsible for the near complete destruction of the Jedi Order during the First Jedi Purge and the attack on Katarr . History . Leadership and origins . The Triumvirate was led by three joint Dark Lords of the Sith : Darth Traya , and her two apprentices , Darth Nihilus , and Darth Sion . These three were all under tutelage at the Trayus Academy on Malachor V . During their time studying the dark side , they learned of specific traits and skills that they had , styling themselves as unique titles for Lords of the Sith . Darth Traya , Lord of Betrayal . Darth Traya , before her fall to the dark side , was a Jedi Master named Kreia . Kreia was very contemplative and philosophical , to the degree that she could be called a Gray Jedi . She was one of the many teachers who trained Revan , who later became an infamous Sith Lord and important figure in galactic history . Revan , along with his friend , Malak , led the crusade against the Mandalorians . Many of her other students succumbed to Revan ' s beliefs and joined him . Kreia was blamed for Revan ' s actions , and was cast out of the Jedi Order . She questioned her beliefs in the gray philosophy . She began searching for answers , meeting those she had affected through her teachings . Eventually , she came to Malachor V , a dead world , powerful in the dark side . She was curious , the Sith ruins drawing her in . She became overpowered with the allure of the dark side , and became Darth Traya , Lord of Betrayal , having been betrayed by the Jedi , and ready to betray in turn . She attained the title of headmistress of the Trayus Academy , able to hold any students willing to fight for the cause of the Sith : to destroy the Jedi . Darth Nihilus , Lord of Hunger . Little was known of Darth Nihilus ' s history . He was most likely a Jedi during the Mandalorian Wars , who became a prisoner . Nonetheless , he ended up fighting at Malachor V . One of the battle ' s few survivors , he was stranded in orbit around the planet . His high Force potential and power were demonstrated when he tore his new flagship , " Ravager " from the gravity well . The ship was barely space - worthy , severely damaged by Mandalorian artillery . It also contained a crew , drained of all life and emotion by its captain . Nihilus came upon the Trayus Academy at some time , seeking training from Traya . He received it , sharing equal prestige with another student , Darth Sion . During his time at the academy , he learned how to drain the Force , create wounds in it , and use Kreia ' s echoes to his advantage . Eventually , his training and abilities made him into a shell of his former self , a wound in the Force , corrupting those around him . Nihilus was different from other Sith in that he never sought to rule the galaxy or to create a new order ; his purpose was to destroy all life everywhere in order to satisfy his hunger . Darth Sion , Lord of Pain . In the wake of the power vacuum that divided the Sith on Korriban , one that emerged was Darth Sion . A twisted and broken shell , Sion was a patchwork of thousands of fragments of his original body . His cracked and decaying body was held together by sheer force of will and the dark side of the Force ; he used the constant intense pain and agony of his condition to fuel his power , his hatred , and his body . Sion fled Korriban , coming to Malachor V , where he found the Trayus Academy , Traya , and training . His brutality and strength were something noted by Traya , but the two soon disliked each other because he did not yearn for knowledge or studies , but for hatred and power . Betrayal , Hunger , and Pain . At the completion of their training , these three were now co - rulers of an Empire . The remnants of Revan and Malak ' s forces soon joined them on Malachor V , where they subtly intervened with galactic affairs , using Traya ' s idea of echoes in the Force , and corrupting Jedi to the dark side . Sion quickly grew impatient of waiting to fight the Jedi and the Republic , while Nihilus grew hungry and needed Force sustenance . The two conspired against Traya for a time , and then , when she was vulnerable , they struck . She was cornered from two sides in the Trayus Core while meditating , and violently subdued . Nihilus used the Force to slam her against a pillar . She reached for her lightsaber , but in vain . Sion then proceeded to beat her and throw her on the floor . During this time , the two Lords used Sever Force to cut her connection to the Force , making her lose the dark side that had corrupted her in the first place . Traya , Lord of Betrayal , was betrayed again . Cast out by both Jedi and Sith , Kreia directed her anger towards the Force itself , treating it like an insidious power . She left the Sith Triumvirate she started , and began to direct her attention toward the Jedi Exile , who would later be the death of all three Lords and the Triumvirate . Sion and Nihilus now had dual control . However , due to their conflicting philosophies and their similar beliefs that the Jedi should be exterminated , they also went their separate ways , each taking a nearly equal section of the Empire . Destroying the Jedi . Their separate pursuits allowed Nihilus and Sion to continue their respective " shadow wars " in peace . Nihilus carried out large - scale exterminations to satisfy his Force hunger , like that of Katarr , while Sion worked silently and brutally , deploying Sith assassins to bait and kill stray Jedi . They came very close to their goal ; only a few known Jedi survived . The Sith , specifically Nihilus , directed its attention towards Onderon and other struggling Republic worlds in an effort to destroy the Republic backbone . Devastation of Katarr . With the new Sith tactics killing off the few remaining Jedi at an alarming rate , the Masters called a meeting on the Miraluka colony of Katarr . As the Miraluka were all Force - sensitive , the planet was a powerful nexus of the Force . The Jedi hoped to use this power to discern the nature of the threat they faced . Their plan worked , too well . Nihilus was attracted to the massive amount of Force energy . Unfortunately this turned against them . He devastated the entire planet with his hunger , killing all the Jedi , natives , and other life on the planet , feasting on the death he felt . Jedi Council member Atris , who was not actually present , fled to Telos IV , a world that would be important later . The sole survivor of the massacre was Visas Marr , whom Nihilus spared for an unknown reason , perhaps out of pity or need of an apprentice . Nonetheless , the blind female became his servant , somewhat devoid of the decay that plagued his ship . Her part in the Sith , if any , is unknown . The aftermath of the Katarr attack left the entire surrounding region blind to the Force which allowed the Sith to move undetected . The last few Jedi fled to different worlds , worlds that were either wounded by war or swarming with life in order to make sensing their presence there nearly impossible . Assassination . Darth Sion , however , had been killing the Jedi with subtler , more brutal methods . Torture , coercion , and traps were some of his favorite tools . Sith Assassins were sent all over the Galaxy , also slaying numerous Jedi , but one at a time . The killers eventually found their way to the Jedi Exile , now in the company of Kreia on the Peragus Mining Facility . Sion came to this area , after deceptively hijacking " Harbinger " from the Republic Navy . However , his prey escaped , but not without Kreia losing her left hand in a bout of words and swords with Sion as a diversion . After the initial purge of the Jedi , he had a more famous kill : Jedi Master Lonna Vash , a member of the Jedi Council , who had been in exile at the Sith Academy on Korriban . This attracted the Jedi Exile and some of her newfound companions , who had been searching for the remaining Jedi . Sion had not forgotten Traya ' s exodus , and recognized the Exile ' s quest as her doing . After a brief conflict , the Exile had to flee , as beckoned by Kreia . Sion wanted to have more revenge , but could not for the time being . Onderon Civil War . A conflict instigated by Nihilus on the behalf of the Triumvirate , the Onderon Civil War divided the planet , and further hindered the Exile . The battles pitted Loyalists , siding with Queen Talia , against General Vaklu , her cousin in charge of the majority of the military , and his Sith allies . The fighting raged all across the city of Iziz , incorporating beasts of Sithspawn and natural Onderon alike . The battle also was on a darker battlefield : Onderon ' s mutual atmosphere moon , Dxun , where the tomb of Freedon Nadd , an ancient Sith Lord , was located . A Sith Master and his hordes of Sith Lords , Assassins , warriors and basic Sith troops were guarding the tomb , as well as performing a ritual around a dark side nexus to turn the tide of the battle . Eventually however , with the help of the Exile , her companions , and Kavar , another sought member of the Jedi Council , the Loyalists won . Nihilus also accumulated a new slave : Colonel Tobin , a veteran and Vaklu supporter . Kreia gave false information to Tobin , after the battle , effectively trapping Nihilus with another insatiable target : Telos IV , the site where Atris had supposedly built a new Jedi Academy to consume . Endgame . Darth Sion ' s path led him to Malachor V , Nihilus ' to Telos IV , with Traya and the Exile visiting both . Kreia had set in motion plans to destroy the Jedi , the Sith , and even the Force itself . She had already killed the remaining Jedi Masters for their failure to see what they had caused , and the Exile ' s point of view . Kreia went to Telos with intentions to fully change Atris , who had long been under the influence of her own archived Sith holocrons . The Exile confronted Atris , while Kreia commented after going to Malachor V . Kreia found Sion , defeating all his Sith Assassins along the way to the Academy . He was brought under her heel once more to serve against the Exile , a somewhat mutual goal . Meanwhile the Republic , the Telos Security Force , the Exile ' s team and her various acquaintances were hard at work combating Darth Nihilus ' fleet , which started to bombard the vital Citadel Station . The invasion of Sith commandos was briefly held off , while the Exile , Visas Marr , and Mandalore Canderous Ordo with his Dxun - trained Mandalorians flew a shuttle to the " Ravager " with the intention of destroying it , and its all - consuming master . Proton detonators were placed , and the Exile ' s companions helped her fight Nihilus , in a quick and decisive battle that drew on the Force bonds that Marr and Nihilus had . Nihilus , Lord of Hunger , had fallen . He disappeared in a manner befitting an evil perversion of a Force ghost , dark energies consuming his body . The " Ravager " was destroyed , and the battle won . The Exile had personal business on Malachor V on two accounts , and so traveled there . She fought and slew the bulk of the Sith Triumvirate , Marauders , Assassins , Lords and regular troopers alike . She defeated Darth Sion in a battle of lightsabers , and then will in an emotional confrontation , where he released himself from the constant pain . She then proceeded to Traya , meditating in the Trayus Core . Kreia dismissed the Exile ' s attempts to " save " her and bring her back to the Light . The argument culminated in a fight that Kreia had hoped for , to complete her plan . The resulting Force echoes of the Exile ' s death would poison , if not kill , the Force , her nemesis . An open but brilliant lightsaber duel resulted , Traya utilizing her full Force arsenal . The Exile wounded Traya by cutting off her remaining hand , but she struck back using telekinetic lightsaber combat , sending three hidden lightsabers at her . The Exile eventually defeated Kreia . As one last gift to the Exile , she gave her prophecies concerning the Force , the Mandalorians , and all her many acquaintances and friends . Then Darth Traya , Lord of Betrayal , died , and the Sith Triumvirate perished with her . What remained of the Sith Triumvirate after these events was ultimately destroyed . Most casualties were directly caused by the Jedi Exile . Military . The Sith Triumvirate utilized the same weapons and technology as Revan ' s Sith Empire . Since it was a remnant of said Empire , its military was virtually the same , using " Interdictor " - class cruisers and Sith fighter s in the navy , Sith trooper s , war droids and Dark Jedi in the army . However , the structuring and classification systems of the Sith and Dark Jedi were different . The Triumvirate used Sith Marauders , Warriors , and Assassins almost exclusively , utilizing each for a unique purpose not found in Revan ' s technologically powered Empire . And then , since it was smaller , the Sith Triumvirate tried to avoid outright battles , preferring deception . It also was directly commanded by the three Sith Lords ; Sion would often send Assassins after a target while he was directly inside the building , and Nihilus would only go into space combat if the " Ravager " was present , to use his unique abilities . The military lacked command structure like other larger systems of government , with no admirals or generals , but instead , Sith Lords or lesser Dark Jedi . The few times that the Triumvirate fought openly was during the Onderon Civil War and the Battle of Telos IV , the former supporting General Vaklu ' s soldiers with Dark Jedi and Sith beast handlers , while the latter apparently used all of their remaining space and ground forces . Behind the scenes . The name " Sith Triumvirate " was first coined for the trio of Darth Traya , Darth Sion and Darth Nihilus by Wookieepedia until authors John Jackson Miller , Rodney Thompson , Sterling Hershey , and Abel G . Peña made the name for the group official in " Knights of the Old Republic Campaign Guide " .
