Shimrra Jamaane Shimrra Jamaane was the Supreme Overlord of the Yuuzhan Vong during the Yuuzhan Vong War , although in truth he was merely a puppet of the Force - sensitive Shamed One Onimi . Born to Domain Jamaane , he was marked from birth as a candidate for Supreme Overlord . Around 29 BBY , he fell under the sway of the former Shaper Onimi , who used his powers to take control of Shimrra . Under Onimi ' s direction , Shimrra overthrew Supreme Overlord Quoreal with the support of many warriors . He then announced the discovery of a new galaxy , and proclaimed that the Yuuzhan Vong were destined to conquer it , whereas Quoreal had made the decision to avoid the galaxy , due to the presence of the living planet Zonama Sekot , which he believed to be a portent of doom . In 25 ABY , the Yuuzhan Vong launched their invasion of the galaxy , beginning the Yuuzhan Vong War . The Yuuzhan Vong made early gains and soon had the New Republic reeling . Three years into the war , Shimrra settled on Yuuzhan ' tar , which would be his home for the rest of the war . He conducted meetings from his palace , directing the war and attempting to quash the " Jeedai " heresy . However , the war took a downward spiral after the Battle of Ebaq 9 , and Shimrra grew increasingly unstable . In 29 ABY , Zonama Sekot — purportedly a sign of doom — appeared above Yuuzhan ' tar , sparking riots and weakening Shimrra ' s already - declining power base . Soon after this , the Battle of Yuuzhan ' tar commenced . Refusing to surrender Yuuzhan ' tar to the Galactic Alliance , Shimrra set fire to large swaths of the planet . Shimrra was finally attacked in his citadel by a trio of Jedi led by Jedi Master Luke Skywalker , who dueled and finally killed the Supreme Overlord . The aftermath of Shimrra ' s demise saw the death of Onimi and the surrender of the Yuuzhan Vong . Biography . Early life and coup . Shimrra , a male Yuuzhan Vong , was born into Domain Jamaane many decades before the Battle of Yavin . The Yuuzhan Vong were an extra - galactic species that had been traveling through the Intergalactic Void for millennia in hopes of finding a new galaxy , after destroying much of their home galaxy in an intra - species war . As the followers of a belief system known as the True Way , the Yuuzhan Vong were devoutly religious , and worshiped several gods , chief among them Yun - Yuuzhan , the creator god . Yuuzhan Vong society was divided into castes , consisting of the Supreme Overlord , warriors , intendants , priests , shapers , workers , and Shamed Ones . Because of their reliance on their gods , the Yuuzhan Vong placed a great deal of importance in their priests , and their god - king , the Supreme Overlord . Only the Supreme Overlord held a link to Yun - Yuuzhan , and all of the other Yuuzhan Vong were completely subordinate to the Supreme Overlord . Shimrra had a twin brother ; they were only the third set of twins in the species ' history . In the previous two instances , one of the twins had killed the other , and then gone on to lead the Yuuzhan Vong during times of crisis . Because he was a twin , and of noble birth , Shimrra was placed into a small group of candidates for the position of Supreme Overlord . As a candidate for Supreme Overlord , Shimrra received many luxuries , and was trained in warfare and religion . Due to the work of Shapers , he grew to an extraordinary size . At the age of seven , Shimrra killed his brother to eliminate a possible rival for the throne , early on displaying aggressiveness and ruthlessness . After many hopeless years traveling through space , the Yuuzhan Vong discovered a galaxy , which they began scouting . In 32 BBY , Supreme Commander Zho Krazhmir , who had been dispatched to scout the galaxy by Supreme Overlord Quoreal , discovered the planet Zonama Sekot in the new galaxy . Zonama Sekot was a sentient planet , one with many similarities to the species ' original homeworld , Yuuzhan ' tar . Ancient legends told of a living planet that would bring about the doom of the Yuuzhan Vong , and so , when informed of this discovery in 29 BBY , Quoreal elected to keep traveling in hopes of finding another galaxy . This decision made him unpopular among the Yuuzhan Vong , particularly Domain Jamaane . At this point , a disgraced former shaper named Onimi decided to act . Earlier , Onimi had learned that the eighth cortex — the final level of Shaping protocol s dispensed directly by the gods and available only to the Supreme Overlord — was empty , contrary to what the species had been taught and believed . Upon discovering this , Onimi realized that the Yuuzhan Vong were doomed if they could not adapt . He attempted to graft yammosk tissue to his brain , but the experiment left him physically deformed , causing him to be marked as a Shamed One and stripped of his rank . However , it also opened him up to the Force , which the Yuuzhan Vong had been cut off from millennia ago . Onimi believed that after traveling through the void for thousands of years , the Yuuzhan Vong would wipe themselves out if they did not have an enemy to direct all their focus toward . Furthermore , he sought to take the place of the gods , and believed that by conquering a new home , the Yuuzhan Vong could ascend to the same level as the gods . Using his powers , he bade Shimrra to take him as his familiar , and jester . Onimi took control of Shimrra , who then launched a coup aimed at seizing the throne . With the aid of many warriors , Shimrra was able to overthrow and kill Quoreal . He then executed many of Quoreal ' s most ardent supporters , as well as the other candidates for the position of Supreme Overlord in an effort to consolidate his power . He also suppressed all knowledge of Zonama Sekot . Having done all this , the new Supreme Overlord announced to the rest of his people the discovery of a new galaxy that he claimed had been revealed to him in a dream from the gods . However , before the Yuuzhan Vong could take the galaxy for their own , they would have to defeat the countless beings already in the galaxy . The Yuuzhan Vong viewed them as infidel s , as they did not worship the Yuuzhan Vong gods , and used machine technology , which was disdained by followers of the True Way . Thus , before the Yuuzhan Vong would be content to settle in the new galaxy , all infidels would have to be killed or converted , and their technology destroyed . Though not all members of the species supported Shimrra and his decisions , the dissidents were silent , as they knew that anyone who opposed Shimrra would be killed . Meanwhile , as Onimi ' s power grew , less and less of the Supreme Overlord ' s original personality remained , although the fact that Onimi was anything more than Shimrra ' s jester remained a secret known only by Onimi , the power behind the throne , and the true Supreme Overlord . The invasion begins . After several decades of preparation , the Yuuzhan Vong launched their invasion of the galaxy in 25 ABY . The ensuing war began well , with the Yuuzhan Vong catching the New Republic completely off - guard . Reluctant to enter into all - out war , the New Republic concentrated on defending the major hyperlane s leading to the Core Worlds and the Colonies , while the Yuuzhan Vong made major advances in the war ' s first six months . Under the command of Warmaster Tsavong Lah , they captured a number of planets , such as Obroa - skai and Ord Mantell , surprising the citizens of the galaxy with their brutality . With the galaxy in turmoil , the Yuuzhan Vong would continue to make gains over the next two years . In 26 ABY , they captured Yavin 4 , home of the Jedi Praxeum , and penetrated the Core , taking the planet Duro . In this year , Onimi discovered the heretical shaper Nen Yim . Yim operated outside of the normal Shaping protocols , and while this normally would have marked her for death , Onimi brought her before Shimrra . The Supreme Overlord proclaimed that she would serve him , working in secret to create new techniques that could be used to fill the eighth cortex , thus providing their species with techniques to be used by the shapers . In 27 ABY , Warmaster Lah enacted Battle Plan Coruscant , which focused on gaining control of Coruscant , the galactic capital . The Yuuzhan Vong were able to defeat the New Republic in the Battle of Coruscant , taking over the planet and leaving the New Republic reeling . The New Republic later attacked Obroa - skai , believing that Shimrra was visiting the planet . Though the New Republic was victorious , they found that the fleet they had attacked was led not by the Supreme Overlord , but by Supreme Commander Komm Karsh . In 28 ABY , Shimrra arrived at Coruscant in his flagship , a specialized Koros - Strohna worldship . With tens of thousands of Yuuzhan Vong on the planet assembled to cheer their leader , the ship landed . The ship eventually became Shimrra ' s Citadel , where the Supreme Overlord ' s throne room was located . Shortly after landing on the planet — now renamed Yuuzhan ' tar , after the Yuuzhan Vong ' s original homeworld — Shimrra held a meeting in his throne room with the Elite , the leaders of the four main castes . There , he chastised Tsavong Lah for the heavy casualties the Yuuzhan Vong had suffered in taking Coruscant , as well as for failing to adapt to new techniques used by the New Republic . He also questioned Executor Nom Anor , who had served as an advance spy , about the government of the other beings of the galaxy , finding their tolerance and democracy to be a new — and foolish — concept . After finishing his interrogation of Anor , he began speaking to Master Shaper Ch ' Gang Hool , who was directing the terraforming of the planet . The effort had been replete with failures , however , and when Hool confessed the fault , a furious Shimrra ordered him to be executed . Soon after this meeting , Shimrra was present at a ceremony dedicating a temple to the creator god Yun - Yuuzhan . The Yuuzhan Vong planned to execute over a hundred captives from the Battle of Coruscant , many of them senators or military officers . However , before the ceremony could begin , the Square of Sacrifice was filled with waste that had , for some reason , been rejected by the maw luur , creatures that disposed of sewage . Angered , Shimrra declared the ritual null and void , and ordered the captives to be killed without onlookers . He then held a meeting in the temple with the Elite , scolding them and questioning if the World Brain — the creature in charge of the terraforming — could be behind the various failures in the process . After ordering that a shaper be killed for the failure of the ceremony , he agreed to let Lah attack the New Republic soon . At some point , the Supreme Overlord met alone with Nom Anor regarding the movements of the New Republic , and the Peace Brigade , a group of beings native to the galaxy that had allied with the Yuuzhan Vong in hopes of being on the winning side . Anor also brought news of Thrackan Sal - Solo , a Corellian politician who had promised to sign a treaty of neutrality with the invaders and disable the Centerpoint Station superweapon if the Yuuzhan Vong would leave the Corellian system alone . Sal - Solo , along with his bodyguard Darjeelai Swan , had come to meet with Shimrra . An interrogation of Swan revealed that the New Republic , not Sal - Solo , was in control of Centerpoint Station . This deception greatly angered Shimrra , although he agreed to meet with the Human . Sal - Solo was ushered into the chamber , where Shimrra informed him that he had decided to accept the Human ' s offer . However , he had altered the deal ; the Yuuzhan Vong would help Sal - Solo ' s Centerpoint Party take control of the Corellian system , after which Shimrra would be in charge of the system . In addition , the Yuuzhan Vong planned not to send Sal - Solo back to the Corellian system , but to make him leader of the Peace Brigade on their headquarters of Ylesia . The citizens of the galaxy saw the Peace Brigaders as traitors , and Shimrra knew that by forcing Sal - Solo to associate with them , the Human would be discredited and kept under the Yuuzhan Vong ' s thumb . When informed of the many changes to his plan , Sal - Solo tried to negotiate his way out ; however , his speech only angered the Supreme Overlord . Infuriated by the fact that an individual he saw as scum would attempt to speak to him like an equal , Shimrra ordered Sal - Solo removed from his chambers to be sent to Ylesia . The Supreme Overlord later held a meeting with Anor and Lah in his private chamber . Anor had collected evidence indicating that the New Republic had fled to the Deep Core moon of Ebaq 9 , and the three planned a surprise attack that Anor felt would break the back of the New Republic . However , the battle was actually a trap created by the New Republic , resulting in the death of Tsavong Lah . After the battle , Shimrra met with the Elite in his throne room , and informed them that the defeat was merely a test from the gods . Swearing revenge on the infidels , he also proclaimed Nom Anor to be a traitor , placing a death sentence on his head . Around this time , Shimrra began to slip from Onimi ' s control , as the Shamed One grew preoccupied with the Trickster Goddess Yun - Harla , whom he blamed for ruining him . The tide turns . In the time after the Battle of Ebaq 9 , the war continued to take a downward turn for the Yuuzhan Vong . As Nen Yim ' s efforts to develop new Shaping protocols continued to produce no results , Shimrra grew increasingly angered . Part of this was due to the recent " Jeedai " heresy led by the prophet Yu ' shaa , who was secretly Nom Anor in disguise . The " Jeedai " heresy was a rapidly growing movement of Shamed Ones that worshiped the Jedi as their saviors , and condemned Shimrra as the " Rainbow - Eyed Enemy , " the being who kept them enslaved . Around this time , Shimrra received a report from Commander Ekh ' m Val . Val had stumbled upon a mysterious planet , and brought back a starship from that world with several features characteristic of Yuuzhan Vong vessels . After hearing details of the apparently living planet , Shimrra knew that it was Zonama Sekot . Seeking to prevent others from learning of the planet ' s existence , he had Val killed , his name removed from the records , and his vessel , the " Noble Sacrifice " , destroyed . In this way , he successfully prevented anyone from learning of Zonama Sekot ' s existence , keeping his power secure . Much to the Supreme Overlord ' s displeasure , Yu ' shaa remained at large in the Coruscant Underworld , and the heresy continued to grow . Several members of his court , such as Prefect s Ash ' ett and Drosh Khalii , were found to be guilty of heresy , as several members of their household were believers in the " Jeedai " movement . On the strength of this evidence , a furious Shimrra had the Prefects and their families killed . However , the evidence had actually been planted by the Priestess Ngaaluh , a secret follower of Yu ' shaa . Nom Anor sought revenge on his enemies , and had arranged for their downfall ; Ash ' ett and Khalii had been innocent of the crimes they were charged with . Unbeknownst to Ngaaluh and Anor , however , was the fact that Shimrra was suspicious of the evidence ; he believed it to be " too " perfect . The Supreme Overlord began conducting his own investigations and interrogated the Yuuzhan Vong heretics that had been planted in the Prefects ' homes . When confronted by their ruler , the terrified heretics confessed that they had merely been placed there , effectively absolving the Prefects of the alleged crimes . When Ngaaluh accused Prefect Zareb of heresy and presented the evidence in front of the Elite , Shimrra questioned the leaders of the various castes . After successfully intimidating several of the most powerful beings in the Yuuzhan Vong Empire , Shimrra turned on Ngaaluh . He revealed that he had learned that she had fabricated the evidence , and ordered his guards to seize her . However , the Priestess committed suicide by poison before they could stop her . Shimrra refused to let the dead Prefects ' honor be restored , claiming that they would stand as a powerful reminder to those who tried to oppose him . The " Jeedai " heresy , he swore , would be stopped , and its members killed . Later , Onimi showed Nen Yim the starship that had been brought to the Supreme Overlord by Ekh ' m Val . The ship was of Sekotan origin , and while examining it , Nen Yim discovered that it had many similarities to the Yuuzhan Vong ' s yorik - et fighters . When Yim revealed her discovery to Shimrra , he ordered her to develop weapons that could be used against the vessels if the Yuuzhan Vong ever met such ships in battles . Despite the fact that Shimrra sought weapons to use against similar ships , he stated that the planet where the ship had come from had been destroyed , as he wished to keep knowledge of Zonama Sekot from spreading among his people . Dissidence and intrigue . A short time after Nen Yim began studying the ship , she fled from Shimrra ' s Citadel with the help of several Jedi and dissident Yuuzhan Vong . In her absence , Shimrra promoted Shaper Adept Qelah Kwaad to the rank of Master Shaper . During his questioning of Kwaad , she stated that she believed that Master Shaper Ahsi Yim , who had been assisting Nen Yim , had played a part in Nen Yim ' s disappearance . An irate Shimrra then had Ahsi Yim killed . Not long after this , he received a message from intendant Phaa Anor . Anor informed the Supreme Overlord that he had been contacted by Nom Anor , who had crucial information for Shimrra . Shimrra spoke to Nom Anor via villip , and the former Executor stated that he was on Zonama Sekot with Nen Yim and the Priest Harrar . When Shimrra proclaimed that such an action was impossible , as Zonama Sekot had been destroyed , Anor told him to contact Harrar , knowing that the Supreme Overlord would be unable to locate him on Yuuzhan ' tar . Realizing that his bluff had been called , and that other Yuuzhan Vong had at last learned of Zonama Sekot , Shimrra was frightened . Nom Anor stated that he could cause his villip to act as a tracer , allowing Shimrra to send a fleet to destroy the planet . As he knew how difficult Zonama Sekot was to destroy , Shimrra was hesitant ; however , the Supreme Overlord was swayed when Nom Anor pledged to sabotage it , enabling the Yuuzhan Vong to destroy the planet . If Anor succeeded , Shimrra — who remained unaware that he was Yu ' shaa — promised to forgive the former Executor and allow him admission to his court once more . The " Red Qurang " , commanded by Ushk Choka , was sent to bring Nom Anor back to Yuuzhan ' tar . Anor did sabotage the planet as promised before Choka arrived ; however , his efforts failed to destroy Zonama Sekot . Unaware of this , Shimrra promoted Anor to the rank of Prefect . Meanwhile , the Supreme Overlord had begun to hear rumors from his spies that , due to the turn in the war ' s tide , a number of Yuuzhan Vong were losing their faith in him , and believed that he had fallen out of favor with the gods . Determined to quash any thoughts of rebellion , he held a meeting with the Elite , warning the high - ranking Yuuzhan Vong of the consequences of betrayal while also putting the blame for the recent losses in battle on the Elite , claiming that they had been disloyal to him , and by extension , the gods . While the Supreme Overlord castigated the Elite , Onimi followed him around , spouting rhymes , as was his custom . After he had finished lecturing his underlings , Shimrra revealed to them his ten Slayers , warriors equipped with unique weapons and biot technology . Because they were a fusion of the priest and warrior castes , the others in his court viewed them with contempt , and proclaimed them to be abominations . When Supreme Commander Chaan questioned Shimrra ' s wisdom in creating the Slayers , the Supreme Overlord ordered him to choose ten of his warriors and do battle with the Slayers . Two of the Slayers were able to defeat Chaan and ten of his warriors , to the shock of the assembled crowd . After the public audience , Shimrra held a private meeting with Nom Anor , revealing his belief that the Yuuzhan Vong ' s greatest enemy was not the Galactic Federation of Free Alliances — as the New Republic was now known — but the gods . The gods , the Supreme Overlord believed , had grown angry because the Yuuzhan Vong no longer needed them . In Shimrra ' s view , the Yuuzhan Vong had become strong enough to survive without their gods , and even take their power . True believers in the gods — such as the majority of Yuuzhan Vong — posed a threat to Shimrra ' s plans to usurp the gods ' power , although he remained confident in his ability to manipulate others and promote his own agenda . However , by this point he was completely insane , his mind twisted by Onimi ' s visions of power and his own hatred of the gods . Three days after the Battle of Caluula , which saw the capture of thousands of infidels , many Yuuzhan Vong , including the Supreme Overlord , met at the Place of Sacrifice on Yuuzhan ' tar for the ceremonial execution of the prisoners . However , before the ritual could begin , the Yuuzhan Vong were attacked by a mass of Shamed Ones , who were able to free a number of the captives . This skirmish , an indication of the increase in strength of the " Jeedai " heresy , infuriated Shimrra , as the movement threatened his power . He ordered three thousand Shamed Ones to be rounded up in the ensuing days , regardless of whether they were believers in the heresy movement , and had them executed . At some point , he was able to convince the errant World Brain to perform its tasks dutifully , rather than sabotaging a number of projects it was supposed to be directing . With this accomplished , the terraforming of Yuuzhan ' tar finally began to proceed smoothly . The appearance of Zonama Sekot . Shimrra later ordered Nas Choka to attack Mon Calamari , the new headquarters of the Galactic Alliance . Though Choka cautioned against such an attack , the Supreme Overlord stated that an assault was necessary to placate the bloodthirsty gods , chiefly Yun - Yuuzhan . Three days later , a fleet commanded by Choka was dispatched from Yuuzhan ' tar . Shimrra and the Elite saw to its departure , with the Supreme Overlord urging Yun - Yuuzhan to aid the fleet in its mission to destroy the infidels on Mon Calamari . By this point , Shimrra had become reviled by many , who had lost all confidence in his leadership ability and believed that the gods no longer favored him . The Yuuzhan Vong launched their assault on Mon Calamari and were able to gain the upper hand over the Galactic Alliance fleet , when suddenly Zonama Sekot appeared in the sky above Yuuzhan ' tar . Nas Choka retreated to Yuuzhan ' tar , while ordering the Yuuzhan Vong ships already there to resist from attacking the strange planet . The sudden appearance of Zonama Sekot — which had been proclaimed by Yu ' shaa to lead to the defeat of Shimrra and the salvation of the Shamed Ones — created chaos on Yuuzhan ' tar . Ecstatic Shamed Ones rioted , while many higher - class Yuuzhan Vong were struck with fear and confusion . After several days with the planet sitting in space near Yuuzhan ' tar , Shimrra called for a private meeting with Nom Anor . Although the Prefect admitted his failure to kill the world earlier , Shimrra revealed that he did not blame Anor — rather , he felt that the gods were at fault . As he explained to Anor , the Supreme Overlord believed that the gods had saved Zonama Sekot and brought it to Yuuzhan ' tar . If they could now destroy it , the Yuuzhan Vong would win the war , he stated . To prevent the gods from interfering , Shimrra ordered to Anor to inform all the priests that they were to cease worshiping any god other than the Trickster , Yun - Harla . If they focused all their rituals on her , Yun - Harla would grow arrogant , and the jealous gods would strike at her , starting a war amongst themselves . This would be payback for the suffering the gods had caused the Yuuzhan Vong during their journey through the Intergalactic Void , Shimrra felt , and while the gods were distracted , the Yuuzhan Vong would destroy Zonama Sekot . Shimrra later met with the Elite , and after mocking them for their cowardice , he informed them that he was aware of the rumors that he was unfit to rule . In addition , Shimrra revealed to them his knowledge of Zonama Sekot , whose existence he had previously denied , and said that after his coup , he had dispatched forces to look for Zonama Sekot . However , as they had been unable to locate the fabled living world , Shimrra stated that he had questioned if it was merely an invention of Quoreal ' s , borne out of cowardice . The appearance of Zonama Sekot , he believed , was but a final test by the gods . Shimrra also claimed that in his prayers to Yun - Harla , a solution had been provided . During a brief skirmish with Galactic Alliance forces on Caluula just days before , all Yuuzhan Vong and their biots on the planet — as well as several other life - forms — had become ill and died . Shimrra deduced that this the result of a chemical weapon developed by the Alliance . One ship had made it back to Yuuzhan ' tar , where it was kept in the atmosphere to prevent it from infecting any other Yuuzhan Vong . The Supreme Overlord planned to crash the ship on Zonama Sekot , an action that would release the pathogen , infect the planet , and eventually kill it . Soon afterward , an armada led by Choka was dispatched to Zonama Sekot with the mission of infecting the planet . The final battle . Shimrra was later interrupted from his meditation by Supreme Commander Laait , who informed the Supreme Overlord that Nas Choka had a message for him . A Galactic Alliance fleet had stood between the Yuuzhan Vong and Zonama Sekot , and though Choka ' s forces had broken through the enemy ' s lines , Zonama Sekot had launched its own defenses — living ships . Shimrra and all the Yuuzhan Vong present were stunned by this news . When several priests questioned whether Shimrra could have been mistaken , the Supreme Overlord had his Slayers execute them , lest his tenuous hold on power continue to slip . In reply to the musings of High Prefect Drathul and High Priest Jakan , he proclaimed that the heretics were responsible for the appearance of these infidel vessels . To settle this matter , Shimrra placed half of the warriors in his Citadel under the command of Nom Anor , who would then direct the execution of every single heretic on Yuuzhan ' tar . Fearing defeat , the Supreme Overlord was also able to convince the World Brain to create fires all across the surface of Yuuzhan ' tar , in hopes of rendering it uninhabitable for anyone . Meanwhile , the Battle of Yuuzhan ' tar raged on , with Galactic Alliance vessels battling Yuuzhan Vong ships above Yuuzhan ' tar . Contemporaneously , the Yuuzhan Vong tried to crash the infected vessel on Zonama Sekot , which was currently in - system near the planet Muscave . A number of Galactic Alliance soldiers and Jedi were able to land on Yuuzhan ' tar , and three Jedi managed to penetrate the Yuuzhan Vong ' s defenses and enter Shimrra ' s Citadel . In his private quarters with Onimi and fifteen Slayers , Shimrra waited for their arrival , keeping in his robes the lightsaber of the Jedi Anakin Solo , who had died during the Mission to Myrkr two years earlier . Soon , the trio made their way to Shimrra ' s private dwelling . There , the Jedi — Luke Skywalker , Jacen Solo , and Jaina Solo — engaged the Slayers in combat . Despite Onimi ' s employment of his powers to shift the Citadel , constantly throwing everyone off - balance , the Slayers were unable to defeat the Jedi , with Luke Skywalker in particular putting up a furious assault . Shimrra soon entered the fight , wielding his Scepter of Power , a special amphistaff . He engaged Skywalker in single combat while the remainder of the Slayers dueled the Solos . The Supreme Overlord was able to gain the upper hand , wrapping his amphistaff around Skywalker . The Jedi also suffered a bite from the creature , spreading poison through his body . With Skywalker at his mercy , Shimrra then drew Solo ' s lightsaber from his robes . As Shimrra moved to decapitate Skywalker , the Jedi used the Force to pull the weapon from the Supreme Overlord ' s hand . With the Yuuzhan Vong distracted , Skywalker quickly sliced his Scepter of Power into pieces , and then cut off Shimrra ' s head , ending his life . Meanwhile , Jacen and Jaina Solo pursued Onimi up to the Citadel ' s private yorik - trema escape vessel , where the Shamed One revealed that he was the true Supreme Overlord , having used his powers to control Shimrra for decades . Jacen Solo was able to kill him , and a short time later , the Yuuzhan Vong fleet over Yuuzhan ' tar — which had failed to destroy Zonama Sekot — learned that Shimrra had died . For the first time in their history , the species was without a Supreme Overlord , their conduit to the gods . In addition , because Shimrra had eliminated all potential challengers , the Yuuzhan Vong had no one to take up his mantle and lead them . Completely lost without their ruler , the species surrendered . Soon after , the Sekot Accords were signed , stating that the Yuuzhan Vong would destroy all their weapons , abandon their war - like ways , and settle on Zonama Sekot — which the Jedi had realized was a seed of the original Yuuzhan ' tar . With this , the war was ended . Personality and traits . Shimrra spent most of the last six decades of his life under the control of Onimi , who used his Force powers to bend Shimrra to his will . During his time as Onimi ' s puppet , Shimrra was characterized by his cruelty , his desire to protect his power , and his ability to manipulate others . Though the Yuuzhan Vong were a violent species , Shimrra had a reputation as being more vicious than most members of his species . Shimrra sought to exterminate all infidels , believing it to be his duty as demanded by the gods . He was ruthless in this quest , and by the end of the Yuuzhan Vong War over one - third of the warrior caste had died . Despite reprimanding Tsavong Lah for wasting his troops , Shimrra was content to sacrifice a great number of Yuuzhan Vong in pursuit of his goals , namely the conquest of the galaxy . He hated the " Jeedai " heresy , decrying its followers and leader , Yu ' shaa , and was willing to kill all the members in the households of two Prefects simply for having heretics in their homes . Even when it was proven that the heretics had merely been planted by Ngaaluh , Shimrra refused to allow the reputations of the now - dead intendants to be restored , stating that their deaths would stand as examples for other Yuuzhan Vong . So great was Shimrra ' s hatred for the heresy that he had Zareb killed after being accused of heresy by Ngaaluh , despite the fact that he had already determined that the Priestess was merely falsifying the evidence . As Supreme Overlord of the Yuuzhan Vong , Shimrra was believed to be the species ' sole link to the most important god , Yun - Yuuzhan , and consequently , had near - unlimited power over his people . He served as the head of all castes , having the authority to command everything from the efforts of the warrior caste to the priests ' worshiping . Shimrra loved his power , and went to great lengths to protect it after overthrowing Quoreal . This included killing many thousands of heretics , as well anyone who opposed his will . Shimrra suppressed all knowledge of Zonama Sekot , and killed Ekh ' m Val for discovering the planet during the Yuuzhan Vong War so as to prevent others from learning of the world that supposedly foretold the Yuuzhan Vong ' s doom . He also kept from his species for decades the knowledge of the emptiness of the eighth cortex , knowing that if such knowledge ever spread , his authority would greatly weaken . For much of his life , Shimrra exerted total control over the Yuuzhan Vong . Ruling with an iron fist , he frequently ignored the advice of his advisors on the Great Council . The Supreme Overlord intimidated other members of his species into submission , and gained a reputation for being ruthless and terrifying . Other Yuuzhan Vong were fearful of him , and even Warmasters trembled in his presence . In addition , Shimrra had an uncanny ability to sense what others were thinking , thanks to Onimi ' s Force - sensitivity . Such was the Supreme Overlord ' s seeming omniscience that High Prefect Yoog Skell once warned Nom Anor to never even think of lying to Shimrra . Shimrra was also very skilled at manipulating others , and was talented in the field of political intrigue . Onimi was able to use his Force powers to subtly influence other Yuuzhan Vong , thus making it appear as though Shimrra had the mysterious ability to affect others ' minds . This added to his reputation as a terrifying , omniscient leader . To help further his stature as an omnipotent vessel of the gods , Shimrra had both his public and private thrones in his Citadel equipped with dovin basal s — creatures that could produce gravitational fields . Through use of these dovin basals , Shimrra made it seem as though those who walked toward his throne were walking uphill , and that to merely approach the Supreme Overlord was a monumental task in itself . Unlike most Yuuzhan Vong , Shimrra did not place his faith in the gods , but sought to overthrow them , much as he had overthrown Quoreal . Under the influence of Onimi , Shimrra grew to hate the gods , and declared war on them . He believed that the Yuuzhan Vong had surpassed them , and were ready to take their place . Shimrra thought that the gods were fearful of this , and that they conspired to destroy the Yuuzhan Vong . The appearance of Zonama Sekot in 29 ABY was just a test , the Supreme Overlord believed . By destroying Zonama Sekot , he felt that the species would prove themselves and force the gods to surrender . By 29 ABY , Shimrra had gone completely insane . Despite his ability to intimidate and manipulate others , many Yuuzhan Vong had lost confidence in Shimrra . His declarations that the gods were the Yuuzhan Vong ' s true enemy , not the Galactic Alliance , were met with skepticism from the Elite , a group that normally was greatly fearful of him .
