Nas Choka Nas Choka was a distinguished Yuuzhan Vong warrior who rose through the ranks of his caste to become the final warmaster of his species . Known more as a tactician and strategist than a martial warrior , Choka nevertheless actively participated in the Jamaane coup of 29 BBY , which saw the ambitious Shimrra of Domain Jamaane become Supreme Overlord of the Yuuzhan Vong . Having pledged his support to the winning faction , Commander Choka was escalated to the position of Supreme Commander of the flagship of the Yuuzhan Vong fleet , as the armada traveled to the galaxy which Shimrra vowed was a promised reward for millennia spent in the Intergalactic Void . When the Yuuzhan Vong finally prosecuted their invasion in 25 ABY , Choka was still with the main body of the fleet . The invaders witnessed several setbacks until Choka took command of the vanguard and managed , by manipulating an alliance with the Hutts , to mount a major offensive against the New Republic ' s vital Fondor Shipyards . The battle went awry , however , when Choka lost half his attack force to the destructive capabilities of Centerpoint Station , an ancient construct in the nearby Corellian system . The vengeful supreme commander descended with his warfleet upon the Hutts , who had betrayed the Yuuzhan Vong at Fondor , and over the next two years laid waste to Hutt Space , conquering the entire territory . The lengthy campaign against the Hutts reaffirmed Choka ' s reputation , and thus when his superior , Warmaster Tsavong Lah , met his death at the Battle of Ebaq 9 , the supreme commander was escalated to the rank of warmaster in Lah ' s stead . Proving to be a very different leader of the warriors than his predecessor had been , Choka made swift progress against the reorganized New Republic with new tactics and agendas . The vendetta against the Jedi was called off , and several threats against the Yuuzhan Vong , such as the Imperial Remnant and the Yevetha species , were attacked or neutralized . A strike against the enemy ' s communications network also bore some success , but Supreme Overlord Shimrra desired a rapid end to the war . Forced , against his better judgment , to carry out a final , decisive strike against the Galactic Alliance ' s capital of Dac , Choka departed Yuuzhan ' tar — formerly Coruscant — with one of the war ' s largest armadas , tasked with finishing off the tenacious enemy . The warmaster soon returned , however , when news reached him that a living world had emerged in the Coruscant system , and that the enemy was planning to reclaim their lost capital . In the last battle of the war , Choka conducted the defense of Yuuzhan ' tar , all the while threatened by the presence of the living planet Zonama Sekot . The battle came to an end when Choka was halted in his efforts by the news of the death of Supreme Overlord Shimrra . The warmaster chose not to join many of his fellow warriors in ritual suicide , and acted as the spokesperson of the Yuuzhan Vong during the Sekot Accords which ended the war . Biography . The journey to war . By the year 29 BBY , Nas Choka , a member of the Yuuzhan Vong warrior caste , held the rank of commander among his species . The Yuuzhan Vong fleet was in the final stages of its long approach to the galaxy to which it had been traveling for generations , where it had been promised by the priests that the wandering Yuuzhan Vong would find their new home . Already at least one subsidiary fleet was operating in the Unknown Regions , under the auspices of Supreme Commander Zho Krazhmir . It was in that region of the galaxy , however , that Krazhmir discovered Zonama Sekot , a living planet which bore a striking resemblance to Yuuzhan ' tar , the original homeworld of the Yuuzhan Vong , destroyed millennia ago during the epic Cremlevian War which had forced the species into the Intergalactic Void . Krazhmir ' s report disconcerted Supreme Overlord Quoreal , the leader of the Yuuzhan Vong , who came to believe that Zonama Sekot was an omen of disaster , as invading a galaxy in which there were living worlds was considered taboo . When Quoreal attempted to retreat from the long awaited invasion , it was Domain Jamaane , already leading the political opposition to the Supreme Overlord , that acted against him . Commander Nas Choka was a member of a group of officers who sided with the ambitious domain and its figurehead , Shimrra . Having pledged their allegiance to the Jamaane , as Choka believed that Shimrra recognized that the warriors needed their war , lest Yuuzhan Vong society further decline , the commander and his cohorts helped to bring about the Jamaane coup , which saw Quoreal toppled from his throne and killed . Nas Choka went on to take part in the execution of the warriors and intendants who had supported the late Supreme Overlord . Whole domains loyal to Quoreal were purged , their members executed , as well as Quoreal ' s advisors and political supporters . Regarding the proclamation by Quoreal ' s priests that Zonama Sekot was an ill omen for the Yuuzhan Vong , Choka remained skeptical , perceiving the declaration as an attempt to deny the warrior caste its invasion . The priests , likewise , joined their master in death . Nas Choka , for his efforts , was promoted to the rank of supreme commander , serving aboard the flagship of the Yuuzhan Vong fleet — a worldship replete with its complement of warships and warriors . The history of the Jamaane coup was distorted and doctored in the memory banks of the Yuuzhan Vong , all rumors of Zonama Sekot smothered — without success . Choka would witness , over the next decades , as the stories of the living planet persisted ; that it had defeated Zho Krazhmir ' s forces in battle , and that it would bring ill tidings to the Yuuzhan Vong . Choka believed none of the rumors , remaining loyal to Shimrra and trusting in the Supreme Overlord ' s communion with the Yuuzhan Vong gods . Indeed , it would be over half a standard century before Quoreal ' s priests were proven correct and their prophecy was fulfilled , all before the very eyes of the warrior who would rise to become Warmaster Nas Choka . Preparations . By 25 ABY , the year the Yuuzhan Vong launched their all - out assault on the galaxy , Choka had gained a reputation as more of a tactician than a martial warrior ; a highly efficient leader whose military prowess and strategies facilitated the capture of many New Republic worlds , even before his arrival in the invasion corridor . Supreme Commander Choka answered directly to the Yuuzhan Vong warmaster , Tsavong Lah , and remained apprised of the actions of the subordinate commanders who were already fighting in the galaxy . Not every military operation , however , went soundly . The Praetorite Vong advance force attempted to manipulate the invasion plans to gain credit for themselves , and were defeated at Helska IV . Shortly thereafter , Commander Shedao Shai and his fleet were lost during the battle at Ithor , although Supreme Commander Choka subsequently learned that it had been Tsavong Lah himself who had engineered the downfall of Domain Shai , which was seen as a threat to the warmaster ' s superiority . Choka took the lesson to heart — ambition among the warrior caste , and the drive to achieve greatness , could win one powerful enemies . Nevertheless , the Yuuzhan Vong warriors continued to conquer worlds , cutting a swath toward Coruscant , the New Republic capital , and the rest of the Core of the galaxy . Before long , however , the supreme commander received word that yet another Yuuzhan Vong scheme had come undone . On this occasion , the priest Harrar , Executor Nom Anor , and Commander Tla had attempted to coordinate a strike against the Jedi , whose Order presented a threat to the success of the invasion . Utilizing a deception sect priestess , Elan , and guided by the strategies of Tla ' s Battle Tactician , Raff , Harrar and Anor staged a false defection , which saw Elan surrender to the New Republic . It was planned that , having granted the defection credibility by means of a series of " re - capture " attempts , the priestess would gain an audience with the Jedi and assassinate as many of the Order as possible with a lethal bioweapon . Shortly after its inception , the deception ploy met failure . Elan was killed during a pitched space battle , much to the displeasure of her father , High Priest Jakan , having failed to kill a single Jedi . Nas Choka , at the time preparing forces at the Yuuzhan Vong shipwomb at Sernpidal , contacted Harrar and the other architects of the plot via a villip communications device in order to deliver his judgment . Nom Anor , already despised by Choka for his union with the ambitious Praetorite Vong , and a much - discussed figure at the court of Supreme Overlord Shimrra , remained , as a member of the intendant caste , outside the supreme commander ' s jurisdiction . Thus the executor , saved from demotion and further punishment due to his birth into the caste that Choka so detested , escaped the warrior ' s wrath . Instead , Commander Tla and his Battle Tactician , Raff , were summoned forward to communicate with Choka . Choka blamed Tla for the scheme ' s failure , but ordered Raff to apprise him of the costliness of the ploy and the progress of the invasion . The tactician suggested either cannibalizing some of the larger ships of the Yuuzhan Vong fleet to replenish the losses suffered during the defection plot , or to divert from the invasion path to conquer new worlds for the growth of the yorik coral which formed the main constituent of Yuuzhan Vong vessels . The tactician also informed Choka of the opportunity presented by Hutt Space to attain these worlds , as Nom Anor had already entered into negotiations with the Hutt leaders , and of the fact that the New Republic had deployed its fleets and was beginning to put to use technology which could better oppose the Yuuzhan Vong . Choka took all this information into consideration ; he rebuffed the notion of cannibalizing larger vessels , and dispatched Commander Malik Carr to Hutt Space . Harrar and Tla were , as punishment , recalled to the Outer Rim . During this time , Choka also sponsored uprisings on planets such as Atzerri and other worlds to the southern rim of the Yuuzhan Vong invasion corridor . Arrival . While Commander Carr and Nom Anor met with the Hutts and begun their negotiations with the species ' leader , Borga Besadii Diori , Choka continued his preparations . He remained apprised of the situation in Hutt Space by Carr , and of Anor ' s involvement in the new scheme , which entailed leaking false intelligence to the Hutts and allowing it to reach the ears of the New Republic Intelligence Service . The supreme commander was unconvinced by the ploy , as Anor ' s failure over the Elan debacle , and his alliance with the Praetorite Vong , was still fresh Choka ' s mind . On the other hand , the Hutts had agreed to furnish the Yuuzhan Vong with worlds , allowing for new ships to be grown , while the Yuuzhan Vong prepared for their next strike . Bearing the salutations of Warmaster Lah for Malik Carr and his troops , as well as a list of warriors whose actions merited promotion , Choka eventually set off from Sernpidal with his force , among which was a young yammosk , creatures used by the Yuuzhan Vong to coordinate their warriors in battle . The supreme commander and his fleet arrived at the world of Runaway Prince , a planet bestowed upon the Yuuzhan Vong by the Hutts as a gesture of good faith . There , with his commanders , subaltern s , and other troops , a richly attired Choka departed his Koros - Strohna worldship and boarded the " Yammka " , Malik Carr ' s warship , whereupon he was received in a lavish ceremony . Ten thousand warriors lined his passage , with incense , perfumes , and music filling the air , and a selection of 200 captives from the conquered planet Gyndine cowered in a corner of the reception chamber . Ceremoniously , Malik Carr approached Choka and transferred command of his forces to the superior warrior . The supreme commander took his seat on a raised dais and addressed the assembled warriors . Firstly , he passed on Tsavong Lah ' s congratulations for their successes in the opening stages of the invasion , as well as his own , before moving on to the matter of promotions . A subordinate proclaimed the list of those to be escalated , and before the congregation four subalterns were affixed with cloaks of command . Choka then announced the end of the escalation ceremonies before turning to the pressing matter of Executor Nom Anor . Rather than escalate the intendant , as Anor expected , Choka criticized the executor heavily , condemning his alliance with the Praetorite Vong , as well as his role in the death of Elan . The two held a brief dispute , before Choka ' s curiosity had him ask Anor just what was so special about Luke Skywalker ' s Jedi Order and why they demanded such costly attention . When Anor attempted to explain the threat posed to the Yuuzhan Vong by the Force , the supreme commander dismissed the notion , citing the True Way of the Yuuzhan Vong religion to be far superior to the " idea " of the Force . Having exhausted the conversation , Choka was informed of Carr ' s and Anor ' s plan to conquer the Core Worlds , and that a hasty departure was required in order to put the next stage of the campaign into effect . Before the supreme commander accompanied Anor and his subordinate , he warned the executor against the dangers of personal ambition . With that , the Gyndine captives were sacrificed , and Choka , Carr , and Anor set off for the world of Tynna . To take Fondor . Tynna , while an important conquest in that its waters could furnish the Yuuzhan Vong with massive dovin basal s with which to strip planetary shields , or creatures , such as the ychna , with which to attack constructs in space , was nevertheless only another step in Malik Carr ' s and Nom Anor ' s scheme to deal a crippling blow to the New Republic . Knowing that the Hutts would secretly communicate information on the Yuuzhan Vong to New Republic Intelligence in order to prevent themselves from making an enemy of either force , Carr and Anor had given Borga Besadii Diori and the other Hutts details of the next locations the Yuuzhan Vong would be attacking . They stated Tynna , Corellia , and Bothawui to be the three upcoming targets , whereas in fact it was the shipyards at Fondor that remained the true goal . Attacking Tynna , however , encouraged the New Republic to trust the Hutt intelligence sources which had provided information on the planet being one of the next Yuuzhan Vong targets . A New Republic spy ship was observed monitoring the conquest of Tynna , and thus Choka , Carr , and Anor knew that the New Republic now awaited strikes at Corellia or Bothawui , as the Hutt intelligence on the first of the three targets had been proven correct . Having routed the 200 starfighters and other forces defending Tynna , Choka and Carr traveled down to the Tanallay Surge complex on the planet ' s surface , leaving their fleet in orbit . Supreme Commander Choka , along with his subordinate , approached the Tynnan delegation outside the Tanallay Surge complex , but the Yuuzhan Vong officer had no interest in communicating with the inhabitants of the planet , who had been tricked by Peace Brigade rs , collaborators loyal to the Yuuzhan Vong , into handing over the world . Instead , Choka signaled a drop ship , which released a host of biotoxins into the waters surrounding the Surge complex . Within moments , the bio - forming of Tynna ' s oceans was underway . His task completed , Nas Choka returned with his ships to the fleet over Runaway Prince and boarded the " Yammka " , where a villip relay had been set up to contact Warmaster Tsavong Lah . Genuflecting before the villip ' s facsimile of the leader of the warrior caste , Choka apprised Lah of the Fondor ploy . To assuage Lah ' s doubts , Choka informed the warmaster that preparations for the attack on the shipyards were already underway ; yorik - et starfighter pilots were readying themselves for the ramming tactics which would wipe out the shipyards , along with any berthed starships , and dovin basal mines were being prepared , with which to seed hyperspace routes between Fondor and its connected systems . Carr also told the warmaster of the trap at Corellia being set up by the New Republic . The Kuati senator Viqi Shesh , who was passing intelligence to the Yuuzhan Vong , had alerted her new masters to the deception in the Corellian system , but had not specified the nature or capabilities of the trap — Centerpoint Station , an ancient construct able , with pulses of gravitic energy , to induce supernovas in stars or swat whole fleets out of space . For the time being , the Yuuzhan Vong saw fit to avoid the unknown threat of the Corellian system . As the time to strike at Fondor drew closer , Choka visited Borga Besadii Diori on Nal Hutta along with Carr and Anor . The Yuuzhan Vong officer toyed with the Hutt , making unsubtle indications that Nal Hutta and its environs could fall to his forces whenever he or his superior chose . Choka also rebuffed the Hutt ' s offer of transporting slaves . Thus , the meeting was conducted with a good deal of tension , as the Yuuzhan Vong and Hutt retinues faced each other while Choka intimated his dominance over the Hutt . Matters escalated when , after Choka asked the Hutt if her species could obtain a Jedi Knight for the Yuuzhan Vong , Borga announced that one — Wurth Skidder — was already aboard a Yuuzhan Vong vessel , the " Crèche " , in the company of her son Randa Besadii Diori . Choka grew angry at the fact that his subordinate on the vessel , Chine - kal , had failed to notify him of this and demanded that he contact the commander . Borga offered her mechanical communications device and Choka rounded on the Hutt , insulting and threatening her , nearly prompting a skirmish in the Hutt ' s throne room . The supreme commander communicated with Chine - kal , whose yammosk - bearing clustership was nearing the world of Kalarba in preparation for the jump to Fondor . The supreme commander ordered Chine - kal to remain in the Kalarba system . Before he left Nal Hutta , he warned Borga that if the Hutts betrayed the Yuuzhan Vong , Hutt Space would be conquered . If they remained loyal , however , Choka promised that the Hutt kajidics could keep their holdings . Shortly after the Yuuzhan Vong delegation departed , Borga sent word to the Jedi that Wurth Skidder could be located along with the " Crèche " at Kalarba . In the process of making the final preparations for the attack , Choka and Carr received word that the " Crèche " had been attacked at Kalarba and was now traveling to Fondor in advance of the main force . This development forced Choka to accelerate his plans , but with the New Republic fleets massed at other worlds , expecting a strike on Corellia , and the hyperspace routes linking Bothawui to Fondor mined , there was little risk in a premature attack . The supreme commander led his armada to Fondor . Against Nas Choka ' s numerical advantage , the New Republic First Fleet , tasked with the defense of the shipyards , was rapidly overwhelmed . Yorik - et pilots acted as ramship s in scores , obliterating the thirty berthed vessels , the shipyard annexes and orbital defenses , before driving down to the planet below . The Yuuzhan Vong fleet fanned out , commencing an orbital bombardment of Fondor and driving back the First Fleet . The " Crèche " , however , was assaulted and boarded a short distance from the main battle , forcing Choka to dispatch warships to aid Chine - kal . Then , just as a Hapan warfleet emerged from hyperspace from the direction of Commenor , a column of energy blazed through the system . On distant Corellia , Centerpoint Station had been fired , and its beam punched through both the newly arrived Hapans and Choka ' s armada without slowing . In an instant , two - thirds of the New Republic ' s reinforcements had been destroyed , along with half of Nas Choka ' s fleet . Choka and his confederates were astounded . In the midst of the confusion , Chine - kal contacted the Yuuzhan Vong officer and relayed the news that the yammosk was dead and that it had been the Hutts who had betrayed the location of the " Crèche " at Kalarba . Disgusted , Nas Choka ordered the remaining half of his forces to prepare to leave . Having inflicted some parting damage on the ruined shipyards and their defenders , the Yuuzhan Vong departed the system . Redemption in Hutt Space . Although Choka believed that his forces had achieved their aims at Fondor , destroying its production capabilities , the battle was seen as a disaster by many in the Yuuzhan Vong hierarchy , not least of all because Choka had taken , in Tsavong Lah ' s opinion , an unimpressive number of captives . While he still held his high rank in the Yuuzhan Vong fleet , Supreme Commander Choka took the initiative and moved swiftly to exact his vengeance upon the Hutts . Malik Carr , for his part , was demoted following the Fondor debacle , relegated to overseeing prisoners on the backwater planet of Selvaris , far from the forefront of the invasion . Choka ' s fleet arrayed itself over Nal Hutta , and initiated a blockade of the Hutt capital , along with the Smuggler ' s Moon , Nar Shaddaa . The system was placed under a state of siege — the Hutts could rely on no New Republic aid after their double - dealing , and were soon mired in the fight of their lives . Choka ' s adversary , Borga the Hutt , defended the capital with only the support of half the kajidics , a force unable to contend with the size of the Yuuzhan Vong armada . With no space fleet threatening his position , Choka ordered Nal Hutta and its moon to be re - created . Both were remotely bombarded with missiles packed with biotoxins and bacterial agents . While Nal Hutta , a world of bogs and muddy marshes , was seen as pestilent , Nar Shaddaa , as an ecumenopolis , was viewed as a religious abomination . Some of the microbes broke down the duracrete on the moon into sand , digesting the buildings . Others attacked metal and transparisteel ; the high towers of Smuggler ' s Moon began to crumble and fall . Further bacteria attacked the Hutts themselves — those who had remained — and wiped out the crime lords in their palaces . Later , creatures were sent against any surviving members of the species . Some of the Hutts were told they were welcome to serve the Yuuzhan Vong , while others were not as fortunate , such as the Besadii . Those of the clan who could escape fled to the worlds of Gamorr , Rodia , and Tatooine , long recognized as Hutt holdings . Choka relayed images of the conquest to Warmaster Tsavong Lah , who came forward from the Outer Rim Territories to personally oversee the next stage of the invasion — the conquest of Duro . Meanwhile , Borga the Hutt attempted to open negotiations with Tsavong Lah in order to win some benefits while it was still possible . The Hutt asked for Tatooine to remain in the hands of the Hutts , but ultimately trade talks failed , and the Hutts prosecuted a fierce resistance campaign against their onetime allies . The Yuuzhan Vong also took the planet Ylesia , once a major Besadii holding and , having killed the Hutt administrator and accepted the government ' s capitulation , grew yammosks in its oceans and allowed the Peace Brigade to use the planet as their headquarters . The world became a police state . Supplied by their smuggler contacts such as Booster Terrik , the Hutts made Choka ' s campaign difficult , and the long , exhaustive struggle to take over a large area of the galaxy raised the supreme commander ' s status considerably . It also served to immerse him in the arts of deception and duplicity , heightening his tactical awareness and encouraging him to become cynical when observing matters of apparent simplicity . The Hutts successfully used ancient war - robots against the Yuuzhan Vong for a time , and a resistance group , the Sisar Runners , was subsequently formed under the leadership of the Hutt Embra . Having formed a coalition of displaced crime lords who wanted to take their territory back from the Yuuzhan Vong , Embra hired mercenaries and other out of work fringers in his quest to reclaim Hutt Space . Choka ordered a portion of his forces to travel to an abandoned Trade Federation battleship drifting near Ylesia , where a cell of Klatooinian mercenaries was striking from ; Choka wanted them exterminated . The Yuuzhan Vong fought through forces of old battle droids successfully and terminated the mercenaries , but learned that Embra had not fled Hutt Space , but was hiding in the deepest bowels of Nar Shaddaa . Choka dispatched his men and a number of Chazrach slaves to find and kill Embra . The Hutt ' s forces managed to outwit them , destroying the controller for the Chazrachs , and Embra ultimately survived , as did her resistance group . In the meantime , the New Republic capital Coruscant was taken , and Warmaster Tsavong Lah , pursuing his strident vendetta against the Jedi Order , continued to direct campaigns from his new seat of power , as Supreme Overlord Shimrra traveled in from the Outer Rim Territories . When the Supreme Overlord did reach Coruscant — now terraformed and renamed Yuuzhan ' tar in honor of the lost Yuuzhan Vong homeworld — Tsavong Lah was able to report on Choka ' s good progress in Hutt Space . Eager for a decisive victory against the New Republic , however , Warmaster Lah was lured shortly afterward to the Deep Core . False intelligence reports indicated that a major New Republic stronghold , known as the Final Redoubt , could be found and destroyed on Ebaq 9 , a small moon in the Treskov system . Enticed not only by the apparent validity of the information , but also by the prospect of capturing the Jedi he had so desired for much of his time leading the fleets , Lah journeyed to Ebaq 9 with a massive armada , whereupon he was trapped , defeated and killed . Nas Choka , his reputation buoyed by the Hutt campaign , was recalled and escalated to the rank of warmaster , in order to fill the vacant position . Choka ' s strategies were seen to be significantly different to those of Tsavong Lah , and although his warriors thought him more than capable , the new warmaster remained convinced that he had been escalated by default . Warmaster Choka . At the time of Choka ' s ascension to the rank of warmaster , the Yuuzhan Vong empire was undergoing several internal difficulties , which were reflected upon the military . A heretical movement , which had come into being in 26 ABY while Choka was in Hutt Space , had expanded and become a threat to the Yuuzhan Vong religion . Shamed Ones , the lowliest of the Yuuzhan Vong , as well as workers , were flocking to the new system of beliefs , which pronounced the Jedi saviors who were the path to a greater standard of living . Tsavong Lah , who had pursued the Jedi tirelessly since a duel with Jacen Solo on Duro , had made the persecution of the Order a priority , and thus the heretical movement had been similarly targeted . Choka continued the violent suppression of the movement , which was brewing in the lower levels of Yuuzhan ' tar , picking up the campaign where his late predecessor had left off . The heresy , however , was not at the time the only concern of the warmaster . The New Republic , which had been victorious first at a battle at Obroa - skai , and later at Ebaq 9 , had subsequently reorganized itself into the Galactic Federation of Free Alliances , led by Chief of State Cal Omas . Warmaster Choka felt that a change of strategy was required . Campaigns were prosecuted against subsidiary threats to the Yuuzhan Vong , in order to acquire new captives for use in the slave armies , to enable the Yuuzhan Vong to season its warriors , and to consolidate its holdings while fighting weaker enemies . Although Nas Choka realized that many more threats , such as the Chiss Ascendancy , the Corporate Sector , and the Hapes Consortium , needed to be neutralized before the Yuuzhan Vong moved against the Galactic Alliance ' s new capital of Dac , in the Calamari system , two new campaigns were launched . Concurrently , Nas Choka ended his predecessor ' s vendetta against the Jedi Order , which he viewed as a minor threat at best . A supreme commander , B ' shith Vorrik , had been dispatched from Yuuzhan Vong positions at the conquered planet of Dubrillion to take the fight to the Imperial Remnant , the last holding of the Galactic Empire which had ruled before the New Republic had taken power . Remnant forces had fought Yuuzhan Vong several times , although , until 29 ABY , no incursion had been made on its territory . Vorrik ' s assault was initially successful , but soon ran afoul when Gilad Pellaeon , an aged Imperial strategist , defeated the Yuuzhan Vong forces at the Battle of Borosk . Pellaeon then directed the forces of the Imperial Remnant to side with the Galactic Alliance , which was not the result Choka had been awaiting . Successes were noted in the Senex - Juvex system , as well as at the distant world of Bakura , where the reptilian Ssi - ruu k were neutralized . On Yuuzhan ' tar , however , the heresy continued to grow , acquiring a mysterious new leader , the Prophet Yu ' shaa . Even with the failure of the attack on the Imperial Remnant , the new warmaster nevertheless had other problems with which to contend . The Yuuzhan Vong advance had now stalled ; supply lines had been sabotaged and resistance cells had formed across the empire . Some success was noted in the eradication of the Yevetha n race , a species of xenophobic warriors deemed as too serious a threat to be ignored , which was annihilated in the Koornacht Cluster . Despite the mixed flow of defeats and victories , the Yuuzhan Vong had essentially not made any serious progress against the Galactic Alliance since the capture of Coruscant . There was to be no advance . Supreme Overlord Shimrra , with whom Choka was now in close contact as a leading member of the Yuuzhan Vong Great Council , directed all attention upon the heresy among the Shamed Ones , which was set upon with violence and executions . Life among the most powerful among the Yuuzhan Vong was fraught with danger , especially one so recently escalated and , at some point , Choka tripled his complement of bodyguards to ensure his personal protection . The warmaster ' s headquarters were located in a command grotto deep within Shimrra ' s Citadel , in fact a Yuuzhan Vong worldship affixed to the surface of the planet . Often directing the progress of the warrior caste from this chamber , Choka spent much of his time in the Hall of Confluence , Shimrra ' s audience chamber in the citadel . A priestess , Ngaaluh , had recently become a permanent fixture at Shimrra ' s court , acting as an inquisitor into the heresy and frequently rooting out Yuuzhan Vong officials as secret supporters of the movement . Choka observed as heretics were brought before the Supreme Overlord , having been identified by Ngaaluh , before being summarily executed . With his fellow caste leaders , Most High Priest Jakan , High Prefect Drathul — both old associates of the warmaster — and Master Shaper Yal Phaath , Choka was forced to dedicate many of his resources to combat the insurrection . Warriors were dispatched into the lower levels to kill any heretics they found . Shimrra made it clear at one meeting that such actions were to continue , proclaiming that any Yuuzhan Vong who failed to show enthusiasm and dedication in stamping out the heresy would be persecuted as a collaborator . As Choka attempted to conduct investigations into the heresy , the priestess Ngaaluh disturbed Yuuzhan Vong hierarchy by exposing a prefect named Ash ' ett as a member of the movement . As Ash ' ett was an intendant , the prefect ' s complicity was not embarrassing for the warmaster , but for instead for High Prefect Drathul , who administered that caste . Still , Shimrra ' s punishment of Prefect Ash ' ett — the execution of the official and his family , as well as a threat to his entire domain — proved that the Supreme Overlord ' s persecution of the heretics demanded total obedience . For the time being , however , Choka took satisfaction in the apparent guilt , and death , of another of the intendants he despised . His warriors continued their investigations and subjugation of the heresy . Internal dissent and external threats . It was around this time that rumors of Zonama Sekot began to return . A commander , Ekh ' m Val , who had been conducting a long - term reconnaissance mission in the Unknown Regions , appeared over Yuuzhan ' tar with his frigate , " Noble Sacrifice " , and claimed to have encountered the living planet ; furthermore , he brought back some of its organic technology . The Supreme Overlord had Choka ' s forces destroy the frigate under suspicion of harboring spies , but not before a single yorik - trema landing craft left the frigate for Yuuzhan ' tar ' s surface . The warmaster remained unaware of Ekh ' m Val ' s discovery , or the living craft , and only followed Shimrra ' s orders . Commander Val disappeared , executed for his discovery , and the Supreme Overlord covered up the affair as best he could . Other problems wracked the Yuuzhan Vong on their new throneworld . The World Brain , which had been installed on the planet to oversee its terraforming into the image of ancient Yuuzhan ' tar , had seemingly gone rogue , ignoring attempts from Shimrra to pacify it and causing difficulties across the planet . Coupled with Ngaaluh ' s exposure of another prefect , Drosh Khalii , as a heretic , the situation seemed stacked against the Yuuzhan Vong and their empire . Ngaaluh ' s inquisition , however , came to an abrupt end shortly after the exposure of Khalii . When the priestess collated new evidence against Prefect Zareb , another of Drathul ' s subordinates , and brought it before the Supreme Overlord , Nas Choka was once again present . Shimrra took the news of another seeming betrayal with an anger which disturbed those watching . The Supreme Overlord questioned Choka ' s failure to discover how so many of his trusted servants were turning to heresy , though the warmaster was swiftly able to deflect attention onto Drathul , citing the intendants as possessing the most heretics . The blaming continued , as Yal Phaath and Jakan similarly came under scrutiny . In the tense atmosphere , Shimrra rounded on Drathul and blamed the high prefect for the corruption . To all present , it appeared that Drathul would be executed , though as it transpired the guards came forward to arrest Ngaaluh . Shimrra then exposed the priestess as the true traitor to his empire — she had manufactured the evidence against the prefects , and was allied with the heretics . Nas Choka was shocked , as were the others present , to see heresy at the court itself ; before she could be questioned , however , Ngaaluh killed herself , bringing an end to the affair . Although Ngaaluh had been exposed and Choka managed to remain in favor with the Supreme Overlord , the heresy was already on the increase , and the Galactic Alliance was on the move . Supreme Commander B ' shith Vorrik launched a strike on the Galactic Alliance communications base at Esfandia , whereupon Vorrik ' s command was defeated by a combined Imperial Remnant and Galactic Alliance force . The loss was sorely felt by Nas Choka . Key worlds encircling Coruscant began to come under threat and fell to the Galactic Alliance . Choka ' s opponents secured Thyferra , which produced the healing agent bacta , and Yag ' Dhul , a strategic hyperspace junction . The warmaster was still stationed over Yuuzhan ' tar aboard the " Yammka " when a Yuuzhan Vong commander , Zhat Lah , who had hitherto been in charge of the defense of Fondor , returned with the remnants of his occupation force . It transpired that the Galactic Alliance had used hit - and - fade tactics — ideal against the over - extended Yuuzhan Vong fleet — to set up a feint at Duro , luring Zhat Lah ' s forces there , before striking suddenly at Fondor and catching the commander ' s garrison unawares . Contrary to typical Yuuzhan Vong practice , which was to fight to the death , Zhat Lah had retreated his forces , preserving two frigates and a battle cruiser rather than expending them against a stronger enemy . Choka surprised the penitent commander by praising Lah ' s initiative . The warmaster voiced his concern that the Yuuzhan Vong had been spread too thinly over too much territory — blaming Tsavong Lah for the situation — and reminded the commander that to defeat the defenders of the galaxy , the Yuuzhan Vong would have to set aside their pride and refusal to surrender or retreat . In order to counter the efficiency of the Galactic Alliance tactics , Choka decided to initiate a full - scale attack on the HoloNet , using the recently developed mabugat kan organisms to destroy the relay stations . Having ordered Zhat Lah to remain to defend Yuuzhan ' tar with a new battle group , the warmaster waited for his strategy of disrupting his enemy ' s communications to bring results . The strike on the HoloNet was successful . A small Galactic Alliance task force arrived in the Bilbringi system , an ideal staging point for an assault on Yuuzhan ' tar . The Yuuzhan Vong fleet there caused heavy losses among the Galactic Alliance forces , who could not call for reinforcements due to the collapse of the HoloNet . Although the task force ultimately escaped , and the Yuuzhan Vong suffered their own losses during the engagement , Choka ' s tactic had seen off the attempt to take Bilbringi . A downside of the disruption of the HoloNet , however , was that the Yuuzhan Vong would not be able to eavesdrop on enemy communications . With an uneasy balance existent between the Yuuzhan Vong and the Galactic Alliance , Warmaster Choka made preparations to scatter the Galactic Alliance forces at Dac , which had created a bastion in the system that would take many Yuuzhan Vong forces to overcome . Nas Choka launched attacks on two worlds , Caluula , in the Tion Hegemony , and Toong ' L . Both planets were ideal staging points for an assault on Dac , and Choka hoped that the obvious Yuuzhan Vong interest in the two worlds would encourage the Galactic Alliance fleets to flee Dac , whereupon they could be hunted down individually . What Choka did not want to do , however , was attack the massed Galactic Alliance forces at Dac , which he felt would no doubt result in huge losses for the Yuuzhan Vong . Supreme Overlord Shimrra , however , was keen for a final strike against the enemy , and began to make plans for a grand sacrifice ceremony , during which over 1 , 000 Galactic Alliance officials would be executed as an offering to the gods , in order to gain their divine favor in the coming campaign . A prison convoy was dispatched to all the Yuuzhan Vong penal colonies in turn to transport prisoners to Yuuzhan ' tar . The struggle for sacrifice . Two months after the Galactic Alliance ' s defeat at Bilbringi , Nas Choka was present at another meeting of Supreme Overlord Shimrra and the upper echelons of the Yuuzhan Vong hierarchy . As with many occasions on Yuuzhan ' tar , there were problems with the World Brain , and the congregation inside the Hall of Confluence was disturbed by a steady fall of stink - beetle s from the sky . The Supreme Overlord addressed his audience and attempted to shed light on the numerous setbacks challenging the Yuuzhan Vong , this time by blaming his followers for not trusting him , and thus not trusting the gods , who had placed Shimrra on the throne . Indeed , the Supreme Overlord ' s hold on the polyp throne appeared tenuous to many . Shimrra spoke of the divisions which had existed among the Yuuzhan Vong during the species ' journey to the galaxy , and attempted to restore his followers ' faith in his leadership by citing events in the past when he had been correct and others had failed — others such as Tsavong Lah , and his father , Czulkang Lah , who had long ago opposed Shimrra . Choka was warned by the Supreme Overlord , in front of the congregation , that the consequences would be dire if he failed Shimrra in the same manner as his predecessors . The Supreme Overlord also revealed the manner by which the Yuuzhan Vong would conquer the insidious enemies of the empire present on Yuuzhan ' tar — resistance fighters and Jedi . Shimrra ' s shapers had created a new breed of warriors , known as Slayers , ten of whom were presented to the congregation . The hybrid warrior - priests caused consternation among the Yuuzhan Vong present , especially the quartet of Royal Seers , as they had the appearance of Shamed Ones . Indeed , one of Choka ' s subordinates , Supreme Commander Chaan , voiced his disapproval , and was subsequently forced to fight the warriors . The meeting ended with further remonstrations from the Supreme Overlord , and Choka and his cohorts prepared for the arrival of the prison convoy and the coming mass sacrifice . Meanwhile , over Caluula , the Yuuzhan Vong were being prevented from taking the world by the defenders of Caluula Station . It so happened that the Galactic Alliance military was apprised of the prison convoy ' s location over the prison planet Selvaris ; the Yuuzhan Vong and Peace Brigade vessels were ambushed , and only the chance escape of some of the Peace Brigade freighters , and timely intervention of a number of Slayer ship s , prevented the Galactic Alliance from absconding with all of the captives . The remaining vessels and captives were brought to Yuuzhan ' tar . While the Peace Brigade ships were forced to remain in orbit , the rest of the convoy was welcomed at a field near Westport , a landing area north of the former Legislative District . Choka accompanied the Yuuzhan Vong Elite and Supreme Overlord Shimrra to the field , where the Galactic Alliance captives and the Peace Brigaders were being held . Also present were the Yuuzhan Vong warriors who had been guarding the convoy , and their commander , Bhu Fath . Fath informed Warmaster Choka that 500 captives had been delivered — a number far below the necessary amount , as Most High Priest Jakan and the Royal Seers pointed out . Choka was nevertheless quick to point out that were it not for the actions of Commander Malik Carr , his former comrade during the Fondor campaign , who had been in control of the Selvaris prison camp and had taken charge of the defense of the convoy , many more captives would have been rescued . Shimrra called out for Carr to be brought before him and , at a motion from the warmaster , the warrior was escalated to the rank of supreme commander . There still remained , however , the issue of the dearth of captives . Bhu Fath recommended that the Peace Brigaders be used as substitutes , but Shimrra forbade it and , having asked Choka for a suitable world upon which the Yuuzhan Vong were fighting a land battle , ordered the Brigaders dispatched to the warmaster ' s suggestion , Corulag , in order to be implanted with surge - coral and to fight as thralls . So as to provide a solution for the lack of captives , Nas Choka suggested to the Supreme Overlord that the defenders of Caluula Station be acquired as prisoners , to replenish the lost sacrifices . In order to secure these new captives , Choka asked Shimrra for permission to double the resources required to take Caluula . The Supreme Overlord acquiesced , and Supreme Commander Malik Carr was dispatched to effect the conquest of the world . Carr was successful in raiding Caluula Station and acquiring the requisite number of captives to allow the ceremony to take place , who were delivered to Yuuzhan ' tar three days later . The event was held in the Place of Sacrifice , and was one of the greatest ceremonies of its kind in generations . With three dozen of his supreme commanders , Nas Choka entered the Place of Sacrifice and took up position near Shimrra ' s throne . As the captives were readied for execution , however , a large contingent of Shamed Ones emerged from hidden entrances in the floor of the square . The slayers closed ranks around the Supreme Overlord as the Shamed Ones began their attack , but it soon became clear , even as the ceremony descended into pandemonium , that the heretics had come to rescue the Galactic Alliance captives . In total , the Shamed Ones absconded with three hundred captives ; Shimrra called for three thousand Shamed Ones to be delivered to an ossuary , known as the Place of Bones , near the Western Sea district , three days later . Warmaster Choka and the rest of the Elite watched as giant beasts executed scores of the Shamed Ones . Further embarrassment , however , ensued as the arrested Yuuzhan Vong went to their deaths cursing Shimrra and his courts , and praising the name of Yu ' shaa , their prophet . Such an occurrence suggested that all Shamed Ones were heretics , not only those who had participated in the movement , which was a shocking development for the Yuuzhan Vong Empire . The path to Dac . Two days after the events in the Place of Bones , a troubled Nas Choka finally decided to voice his fears to the Supreme Overlord . The capture of Caluula and Toong ' l had failed to cause the retreat of the Galactic Alliance fleets at Dac . The warmaster was convinced that a period of consolidation was necessary ; the current Yuuzhan Vong holdings would be fortified , and the Galactic Alliance could be pushed back from the Mid Rim to a single region , where they could be destroyed in one battle . The warmaster delivered his advice alone , in the Hall of Confluence , with no support from the ranks of the Elite watching from the sidelines . As Choka feared , the Supreme Overlord believed that the Galactic Alliance had already been forced back into one region — the Calamari sector . In vain , Nas Choka spoke of the strong pockets of resistance located in the Hapes Consortium , the Chiss Ascendancy , and the Corporate Sector , as well as the losses incurred during the Remnant campaign , at Esfandia and at Bilbringi . The Supreme Overlord gave little heed to Choka ' s warnings , and instructed the warmaster to prepare for the strike against Dac . Choka retired to his command grotto beneath the citadel , where he observed a map of the galactic arena , joined by a warrior - seer and a tactician . Intending to follow his superior ' s orders to the letter , Choka warned his subordinates against criticizing Shimrra ' s decision , even though he personally disagreed with the attack on the watery world . Fleets from distant star systems were massing in the Calamari system , and Choka and his tactician admitted that alliances with the Remnant , the Yevetha and even the Hutts would have better served the Yuuzhan Vong than their destruction ; the attacks on the galaxy ' s various factions had only served to unite it more firmly against Shimrra ' s rule . Choka also admitted that his strategy of fortifying Caluula and Toong ' l to encourage the Galactic Alliance to disperse without an actual attack , had failed — the enemy commanders remained in position , indicating that either they would disperse upon Choka ' s arrival , after the warmaster had withdrawn warships from across all Yuuzhan Vong territories to amass the armada . The other possibility was that Supreme Commander Sien Sovv and his cohorts had prepared some form of a counterattack . Such uncertainties troubled the warmaster , and he felt that more time was required to study the situation . Choka did not rule out the possibility that the Galactic Alliance was preparing for a strike on Yuuzhan ' tar itself ; in fact , the warmaster encouraged the notion , as it would entail a battle tilted in the favor of the Yuuzhan Vong . His warrior - seer informed him that she would attempt to delay the timing of the attack on Dac , but Choka knew that the Supreme Overlord would see through such a deception . Instead , he ordered that the Yuuzhan Vong sleeper spy network should be activated , in order to accrue information on the nature of the Galactic Alliance strategy . Several days later , Nas Choka received word from Supreme Overlord Shimrra that the attack on Dac was to occur in three days . The news frustrated and angered the warmaster , who went to his command grotto to hear the report of his intelligence analysts . Choka was informed of a large - scale rise in enemy activity , across great expanses of the galaxy , and that half the fleet defending Dac had dispersed ; he felt that it was a diversion , its purpose unknown due to the destruction of the HoloNet , an action which Choka found himself regretting . Likewise informed that the commander of the yammosk emplacement on Caluula , Malik Carr , had given permission for scientific teams to visit the occupied world , Choka ordered his tenders to bring him a villip so that he could confer with Carr . The warmaster ultimately decided that the Galactic Alliance ' s target was their lost capital , and took measures to prevent its recapture by the enemy . Aware of the build - up of activity at Contruum , an Expansion Region planet which was an ideal staging point for an attack on Yuuzhan ' tar , Choka decided that the Galactic Alliance fleets would mass there . Therefore , in order to trick his opponents , Choka decided not to use Caluula and Toong ' l in his campaign at all . He decided that rather than retreat the armada via the two worlds , which had , according the intelligence provided by his analysts , been compromised , a different route back to Yuuzhan ' tar would be cleared in secret . In this manner , if the Galactic Alliance did launch an attack on Yuuzhan ' tar Choka ' s fleets could return quickly along the Perlemian Trade Route , to strike at Contruum , bypassing any traps laid at Caluula and Toong ' l . After the three days had passed , the Dac armada was arrayed over Yuuzhan ' tar , daubed in the blood of the sacrificed captives and readied for departure . Shimrra delivered an address to the assembled armada , speaking of the necessity of a final battle against the denizens of the galaxy and the ongoing work of the Yuuzhan Vong to purify their promised domain . With a massed volley of plasma , launched into Coruscant Prime as a salute to the Supreme Overlord and the gods , the armada departed , led by Warmaster Nas Choka aboard the " Yammka ' s Mount " , a new vessel which had been created to serve as the armada ' s flagship . The Battle of Dac . The armada , organized into the formation of a multi - tentacled yammosk , moved towards Dac . Choka ' s massive force had to exit hyperspace at a transit point on the Perlemian Trade Route , which had been mined by the Galactic Alliance . The armada incurred minor losses before the leading vessels were able to clear the passive defenses . Instead of jumping directly from the Perlemian transit point to the Calamari system , however , Choka moved his armada through the Qotile system , where the world of Quermia was located . As with the Perlemian transit point , the Quermia transit point had similarly been mined , and once again the armada suffered losses . The warmaster ' s tactic baffled his opponents , as it appeared to them to be an unnecessary additional hyperspace jump . Unbeknownst to the Galactic Alliance commanders , Choka ' s armada was clearing another route back to Yuuzhan ' tar should the need arise . Having destroyed the minefields at the two transit points , the warmaster was now content that if necessary , his forces could return unmolested to other theaters of engagement , such as Contruum . His armada reverted from hyperspace at the farthest reaches of the Calamari system , near a frozen comet known as Iceberg Three . Immediately , Choka ' s force was accosted by a Galactic Alliance attack . Thousands of probe droids were launched into the armada , which broadcast the gravitic signals of Galactic Alliance starfighters . The Yuuzhan Vong pilots set to work destroying the machines , unaware of their true nature , and meanwhile the probe droids communicated firing solutions and other pertinent data back to the defenders of Dac . The outward " tentacles " of the armada were then assaulted by waves of enemy starfighters , opening up firing lanes which distant Galactic Alliance capital ships poured turbolaser blasts down . Choka ' s forces took heavy losses in the barrage , but the warmaster had only been biding his time . The Yuuzhan Vong capital vessels poured plasma volleys down the Galactic Alliance ' s own firing lanes into the paths of the oncoming starfighters which had rushed in to continue the fight . Numerous enemy vessels were destroyed , and the armada rotated itself , bringing fresh warships into action . Deeming the losses incurred in the opening engagement as acceptable , Choka was irritated by what he viewed as a cowardly use of machines . The supreme commander of the " Yammka ' s Mount " , Loiric Kaan , delivered the report ; when the officer commented on the futility of the Galactic Alliance defense , Choka had him escorted from the command chamber , as he believed the supreme commander ' s presence to be equally pointless . The warmaster turned back to the unfolding battle , ordering more volleys of plasma to be directed down the firing lanes between the armada ' s tentacles against the enemy starfighters . Once scores of the small craft had been destroyed , the warmaster brought his matalok cruisers to the fore , to act as the fleet ' s spearhead . Still , however , Choka was aware that matters were amiss . With only half the fleet present at Dac , he knew that the Galactic Alliance had staged a feint . Following a brief conversation with Supreme Overlord Shimrra via villip , during which the ruler of the Yuuzhan Vong gave Choka encouragement , the warmaster ordered just under half of his armada to depart the battle for Contruum , to eradicate the Galactic Alliance forces there before they could strike at Yuuzhan ' tar . The domain groups of Shen ' g , Paasar , Eklut , and Taav , which made up the departing half of the armada , separated from Choka ' s force as the warmaster drove his flotilla past Iceberg Three to Sep Elopor , a gas giant further into the system . As Choka ' s remaining forces moved , they were accosted by destroyers on either side as the Galactic Alliance attempted to divert the attention of the armada ' s defenses . Other Galactic Alliance battle groups fled before the armada , which continued to fire volleys of plasma against the attacking starfighters . Choka ' s force bore down on Sep Elopon and Mon Eron , the latter of which was an inhabited world , as the warmaster raced to defeat the Galactic Alliance defenders . Still hours away from Dac itself , the armada met heavy resistance from its opponent battle groups ; with half of the flotilla gone , the Battle of Dac had become a more even struggle , and the Yuuzhan Vong fought with added ferocity . It was during this stage of the battle that Choka was contacted by Saluup Fing , the supreme commander in charge of Yuuzhan ' tar ' s defense , with urgent news that shocked the warmaster . Over the Yuuzhan Vong capital , a planet had appeared from hyperspace . Immediately Nas Choka ordered the armada ' s withdrawal , and the entire force leapt to hyperspace . Additional battle groups were called in from Hutt Space and other sectors . The warmaster ordered its reversion somewhere in the Mid Rim , so that he could contact Supreme Commander Fing again and hear a follow - up report . Choka ordered all of his crew to leave the command chamber , except his tactician , while they listened to Fing ' s report . The planet ' s arrival had resulted in massive groundquakes across Yuuzhan ' tar , hurling a moon out of orbit to slingshot across the planet ' s surface , and had wiped out the Rainbow Bridge which had been created during Coruscant ' s terraforming to simulate the ancient rings of ancestral Yuuzhan ' tar . Choka ordered the supreme commander to remain over Yuuzhan ' tar , and to take no action against the recently arrived planet . The warmaster ' s tactician nervously broached the subject of a living world , encountered by Zho Krazhmir during Quoreal ' s reign — a rumor which Nas Choka was well accustomed to hearing . Now , however , the warmaster had to grant the legend of Zonama Sekot his attention . Although the pragmatic warrior did not view the living world as a portent of defeat , he did fear its military capabilities . Choka considered his tactician ' s suggestion that the world was a fabrication , created by the Galactic Alliance , but was more inclined to believe that it was indeed Zonama Sekot . Putting on a display of confidence , the warmaster proclaimed that against the two returning halves of the armada , as well as the coming of additional battle groups , no world of any kind could prevail . Defending the capital . On the return of the Yuuzhan Vong armada and subsidiary fleets to the Coruscant system , Warmaster Choka was ordered by Shimrra to refrain from moving against the living world . In the shadow of Zonama Sekot , which orbited Coruscant Prime between the insystem worlds of Muscave and Stentat , Yuuzhan ' tar was in turmoil . The falling debris from the Rainbow Bridge , as well as the massive structural damage the new capital had sustained , had thrown both the planet ' s defenses and populace into disarray , prompting a mass uprising from the heretics , who viewed the living planet as a holy world whose arrival had been foretold in prophecy . Further disconcerting updates reached the warmaster — several Yuuzhan Vong battle groups , such as those of domains Muyel and Lacap , had elected to disobey the recall order , and remained in the territories assigned to them by Shimrra . Choka traveled down to the citadel with his supreme commanders in order to be present at an emergency gathering of the Elite in the Hall of Confluence . Once there , the warmaster was made privy to Shimrra ' s plan for the destruction of Zonama Sekot , which the Supreme Overlord announced to all Yuuzhan Vong present . To the shock of the Elite , Shimrra admitted that the living world was indeed the same planet whose existence he had denied when Quoreal had been ousted from the throne and killed . The Supreme Overlord claimed that Zonama Sekot was a test , engineered by the Yuuzhan Vong gods , as one final trial for the Yuuzhan Vong . Citing a prophecy by which he proclaimed to have been visited , Shimrra pronounced that Yun - Harla , the goddess of deception , had , to aid her subjects in their final test , granted the Yuuzhan Vong a weapon with which Zonama Sekot could be vanquished . The Galactic Alliance had created a potent anti - Yuuzhan Vong bioweapon , which they had deployed on the planet Caluula . From Caluula , one lone vessel had escaped , infected with the lethal virus . Shimrra shouted that the infected vessel should be taken to Zonama Sekot and used to poison the living world , which was no doubt connected to Yuuzhan Vong biochemistry . The Supreme Overlord ordered Warmaster Choka and his subordinates to enact his commands . Muscave . Warmaster Choka , his faith in Shimrra reinforced , accepted his Supreme Overlord ' s commands at face value . While he trusted emphatically in the Supreme Overlord , however , Choka was not as convinced by Shimrra ' s trust in the goddess Yun - Harla , who was believed to have associated with Jaina Solo , slayer of Tsavong Lah . Choka ' s faith resided firmly with Yun - Yammka , the god of war , and before the battle was joined he commanded a coven of the priests of Yun - Yammka to accompany the armada and make a blood - offering to the god of war . The warmaster felt that an offering to the patron god of the warriors would reinforce the faith of those who fought at his command — it had become common knowledge that the fact that the gods were testing the Yuuzhan Vong meant that their divine support temporarily rested tacitly with the Galactic Alliance , and openly with Zonama Sekot . Having traveled back up to the " Yammka ' s Mount " in orbit , Nas Choka prepared to lead his armada to Muscave , an outer - system world where the Galactic Alliance Second Fleet and other forces were assembling . Before departure , Choka spoke to the crew of the infected Yuuzhan Vong vessel , led by a dying shaper . The warmaster encouraged the shaper in her mission to take the virus to Zonama Sekot , and , as the vessel was dying itself , followed the advice of his tactician that a larger warship should ingest the ailing vessel and carry it to Zonama Sekot in case it failed in space . As the Galactic Alliance forces had massed at Muscave and block the path to the living world , Choka planned to break through their line and attack Zonama Sekot . At the same time , he was wary that the Galactic Alliance fleets which had been assembling at Contruum , which had never been engaged by the second half of the Dac armada , were likely to appear over Yuuzhan ' tar and attempt a capture of the capital . Tasked with destroying Zonama Sekot , Choka decided that he had to entrust temporarily the defense of the capital to Shimrra , until the gods rejoined the Yuuzhan Vong following the death of the living world . The warmaster did , however , leave a number of his warships in orbit over Yuuzhan ' tar as a home defense fleet before departing for Muscave . Choka ' s attack on the Galactic Alliance battle line at Muscave was intended to lure the enemy out away from Zonama Sekot , his true target . An hour after Choka ' s departure for Muscave the Galactic Alliance Fourth Fleet emerged over Yuuzhan ' tar and began to land troops on the planet , but by then Choka was committed to the pitched battle over Muscave . His armada traded salvos with the Galactic Alliance line , overwhelming the enemy , while a subsidiary task force , with the infected vessel among it , detached from his fleet and made an in - system hyperspace jump to Zonama Sekot . Once again , Choka soon received urgent news . The pilots of the yorik - et starfighters which the task force had sent forth to attack Zonama Sekot ' s few defending craft had discovered that they were engaging living vessels . Furthermore , Nas Choka was informed by the commander of the task force that the yammosks had grown confused directing the Yuuzhan Vong against other living vessels . Desiring permission to attack Zonama Sekot with capital ships , the warmaster instructed Supreme Commander Laait to bring the news to Supreme Overlord Shimrra on Yuuzhan ' tar . The information sent the Elite into an uproar — some felt that the gods were not granting the defenders of the galaxy tacit support , but were openly opposed to Yuuzhan Vong victory , rendering suspect Shimrra ' s assertion that the species was merely being tested . The Supreme Overlord ordered all heretics and Shamed Ones on Yuuzhan ' tar to be killed , prompting what amounted to civil war on the capital . As the clash at Muscave intensified , Choka ' s Zonama Sekot task force remained 200 , 000 kilometers distant from the living world , awaiting further reinforcements for an all - out assault on the planet . Meanwhile , the Galactic Alliance forces over Yuuzhan ' tar continued to land thousands of troops on the surface , who joined with the Shamed Ones and followers of the heresy to fight Shimrra ' s warriors . Zonama Sekot . Choka dispatched capital ships to assist the Zonama Sekot task force . Moments after the capital ships begun their advance on the world , a Hapan warfleet emerged from hyperspace and blocked their path , much as had occurred at the First Battle of Fondor four years previously . Adding their own firepower to that of the Hapans were the defenses of Zonama Sekot itself , which sent barrages of ion fire against the oncoming Yuuzhan Vong . With the living vessels of Zonama Sekot firing upon them , as well as the massed firepower of the Hapans and the ships of the Smugglers ' Alliance , a Galactic Alliance - aligned flotilla , the Yuuzhan Vong turned upon the infected warship which traveled among them . The warship was cracked open , releasing the dying craft within , which began to make its path towards Zonama Sekot . Nas Choka remained at Muscave , where the clash between the two warfleets had devolved into a hectic brawl . The warmaster presented " Yammka ' s Mount " as the primary target , despite the massive damage the vessel was incurring , and held the Galactic Alliance forces at Muscave . Choka knew that his opponents felt they were succeeding in holding his armada at Muscave while the conquest of Yuuzhan ' tar took place , but the warmaster bided his time , equally aware that he was luring his enemy into a false sense of security . Receiving word that Traest Kre ' fey , admiral of the Galactic Alliance First Fleet and one of the leading military minds among the opposition , had emerged in the Coruscant system from Contruum , Choka realized that he had to press on to destroy Zonama Sekot quickly . His tactician conveyed news from Yuuzhan ' tar — the planet was under heavy siege , but the World Brain was holding its enemies at bay . Shimrra was safe in his citadel , and had sent his blessings to Choka . The warmaster felt that blessings were useless if he failed to destroy Zonama Sekot , and , when he learned of the involvement of the Hapans , he ordered four domain groups to move subtlety into position to attack the Hapans , paving the way for the infected vessel to eliminate the threat of the living world . As domain groups of Tivvik , Tsun , Vorrik , and Karsh approached the living world and assaulted the Hapan defense line , bringing the total number of supreme commanders attacking the planet up to six , elements of the Galactic Alliance Second Fleet broke away from the engagement at Muscave to hurry to the Zonama Sekot ' s defense . Although the Jedi pilots in their living craft , and the planet ' s own weapons , had seen off scores of yorik - et , the Yuuzhan Vong task force pressed on , with Choka providing guidance from the battle over Muscave . At Muscave , the engagement was drawing to a close ; space around the outer - system world was littered with destroyed warships , more of the hulks belonging to the Galactic Alliance than to the Yuuzhan Vong . The warmaster ' s Muscave armada had suffered extensive losses but , as his supreme commanders reported in with news of Zonama Sekot , Choka remained confident that his name would be added to the roster of legendary Yuuzhan Vong warriors , and that the Second Battle of Coruscant would rank among the greatest battles in Yuuzhan Vong history . Supreme Commander Tivvik informed Choka that Zonama Sekot ' s defenses had fallen silent , and that the living ships defending it were immobile . Rather than rejoice or doubt the news , Choka ordered Supreme Commanders Tivvik and Sla Tsun to sacrifice themselves by escorting the infected vessel to the surface of the world . To minimize the risk of contagion , all other Yuuzhan Vong ships were ordered to retreat . The warmaster gave Tsun and Tivvik final encouragement , before he was informed that Jedi had penetrated Shimrra ' s citadel , the World Brain was passive , and that Shamed Ones and Galactic Alliance troops held much of the planet . The warmaster comforted his tactician with the opinion that the Supreme Overlord could never be captured or killed , as the Yuuzhan Vong had fulfilled his orders , and overcome the test of the gods , by defeating Zonama Sekot . Confident that the living world would die without his presence anyway , Choka ordered some forces to remain at Muscave , before leading the remains of his armada to pursue Kre ' fey ' s fleet to Yuuzhan ' tar . Yuuzhan ' tar . " Yammka ' s Mount " and the much of the armada emerged over Yuuzhan ' tar , whereupon Warmaster Nas Choka received the report that Supreme Overlord Shimrra Shimrra was dead , killed by the Jedi who had invaded his worldship - citadel . Still putting his faith in the fact that the gods would not have deserted Shimrra or the Yuuzhan Vong after they had successfully overcome the " test " of Zonama Sekot , Choka refused to believe the rumor . His tactician informed him that the announcement had been made by the priest Harrar , who had defected to the Galactic Alliance . Nom Anor , Nas Choka ' s old foe , had also been revealed to be Yu ' shaa , the prophet of the Shamed Ones ; such developments concerned the warmaster , but none forced him to recount his faith . Choka ' s tactician persisted , however , in presenting the leader of the warriors with rumors and possibilities — that the Jedi had overrun Shimrra ' s inner sanctum and killed the Supreme Overlord , or that the silence of Zonama Sekot ' s weapons was not a sign of defeat but of certainty in its victory . As Nas Choka attempted to come to a conclusion , he received word that Shimrra ' s worldship - citadel had launched from the surface of Yuuzhan ' tar , proving that the Supreme Overlord was still alive . His spirits buoyed by Shimrra ' s apparent survival , Choka ordered his entire command to attack the " Ralroost " , Galactic Alliance Admiral Traest Kre ' fey ' s flagship . Even as the " Ralroost " was overwhelmed by the onslaught , Nas Choka watched Shimrra ' s giant vessel rise unsteadily into orbit with unease , his nervousness heightened by the Supreme Overlord ' s failure to communicate with the fleet . Having retained his faith in Shimrra ' s cause for so long , the warmaster was aghast to see the worldship - citadel suddenly fracture and vent atmosphere , signifying both its death and that of the Supreme Overlord . The enormous vessel exploded at the far reaches of Yuuzhan ' tar ' s orbit , the force of the detonation crippling much of the Yuuzhan Vong home fleet defending the capital . With Shimrra ' s death , Nas Choka knew , came the end of the war . Without the Supreme Overlord , who acted as the conduit of the will of the gods , the Yuuzhan Vong were cut off from the divine pantheon — a deeply religious species with no ability to follow the will of the gods . The warmaster felt that the Yuuzhan Vong had been totally abandoned , relegated to the status of Shamed Ones , with no purpose in fighting now that there was no hope of salvation in the Yuuzhan Vong afterlife . Under the expectant gaze of his subordinates , Warmaster Choka addressed his supreme commanders via villip . He informed his subordinates that the Yuuzhan Vong were a godless species , abandoned by their deities , and that the only options left to the species were ritual suicide , surrender , or death in battle . While his command crew opted to kill themselves , many Yuuzhan Vong chose to drive their ships into collisions with those of the Galactic Alliance . A defeated Nas Choka stood and watched from the command chamber of " Yammka ' s Mount " . The last warmaster . Over Zonama Sekot , the vessel infected with Alpha Red was repulsed by the living planet ' s defenses and harmlessly sent into space . The attempt to poison the living world had failed . The Yuuzhan Vong pilots were brought to the surface of the planet , where their technology was rendered docile — amphistaff s slithered into the undergrowth , and projectile weapons flew off into the sky . News of these occurrences reached Nas Choka , who viewed the world as anathema for the Yuuzhan Vong . For days , while the Galactic Alliance sorted through the aftermath of the war ' s last battle , Choka underwent ritual bloodletting . The remnants of the Yuuzhan Vong armada , once Choka recalled the flotillas from Muscave and Zonama Sekot , was left 2 , 000 , 000 kilometers away from Coruscant , though none of Choka ' s remaining forces were willing to fight , nor was their warmaster . While Nas Choka refrained from communicating with the Galactic Alliance , the armada ' s passivity left the opposing fleets at a stand - off for four days , until on the fifth morning the supreme commander of the Yuuzhan ' tar defense fleet agreed to act as a liaison . Villip transmissions were set up , and it was agreed that Nas Choka and several of his subordinates would be transferred to the " Ralroost " to discuss the terms of the Yuuzhan Vong surrender . The warmaster remained in inner turmoil ; uncertain of the reasoning behind the gods ' abandonment of the Yuuzhan Vong , or whether the blame lay with Shimrra or the Yuuzhan Vong as a species . The warmaster and five of his supreme commanders submitted to a personal search before they were allowed to board the Galactic Alliance shuttle which conveyed them to the " Ralroost " . Choka kept with him his baton of rank , the ceremonial amphistaff known as a tsaisi which denoted his rank of warmaster . The ceremony was held in the docking bay of the " Ralroost " ; upon disembarking from the shuttle , Choka looked out over the journalists , musicians , Galactic Alliance officials , Yuuzhan Vong interpreters , and defectors who were present to observe or take part in the surrender . Warmaster Choka and his supreme commanders sat facing a semicircle of Galactic Alliance commanders , Jedi , and the members of the Advisory Council . Also present were the remaining members of the Elite — Master Shaper Qelah Kwaad and Most High Priest Jakan . High Prefect Drathul had perished , along with Nom Anor , during the battle . In front of the assembly , Choka proffered his tsaisi and announced the total surrender of the Yuuzhan Vong . The warmaster then requested that he be allowed to kill himself , but Supreme Commander Sien Sovv denied him the opportunity . Confused at Sovv ' s statement that there would be no executions , Choka assumed that the Yuuzhan Vong would be enslaved . Jakan and Harrar urged the warmaster to listen to the terms of surrender . Nas Choka remained skeptical , aware that the warrior caste he commanded had no role in a peacetime scenario . The warmaster was then addressed by Luke Skywalker , who proclaimed that the warrior caste would have to renounce its violence and surrender itself to Zonama Sekot . The announcement appalled Choka , who viewed it as worse than execution , calling for the warriors to be at least sent back into the Intergalactic Void to die . Harrar attempted to calm the warrior , but Choka adhered to his belief that the warrior caste had everything to lose with its incarceration on the living world . As it was revealed by Harrar that Zonama Sekot was itself the living offspring of the ancestral Yuuzhan ' tar , Choka forewent his alarm for bitterness . The priest tried to explain that the god of war , Yun - Yammka , by whom Choka swore , was a concoction of the Yuuzhan Vong , a deity created when the species had turned to warfare in the distant past . The warmaster nevertheless believed that Harrar had been deceived , yet resigned himself , and the warrior caste , to a future on Zonama Sekot . Skywalker explained that the living world would transport the Yuuzhan Vong to the Unknown Regions , were they would be safe , and that there the Yuuzhan Vong could create a new society . Before the Sekot Accords were concluded , Choka agreed to cooperate with Kre ' fey and Sovv in removing all the entrenched Yuuzhan Vong pockets of resistance across the galaxy , and pledged that Yuuzhan Vong shapers would aid in Coruscant ' s recovery . Immediately following the summit on the " Ralroost " , the Yuuzhan Vong warriors were loaded into Galactic Alliance vessels . The warships of the Yuuzhan Vong armada were subsequently launched into Coruscant Prime , with all of the armaments of the warrior caste aboard . During the next week , tens of thousands of Yuuzhan Vong were transported down to Zonama Sekot , where they set to work repairing the damage wrought by Zho Krazhmir ' s attack decades prior . Meanwhile , Choka issued recall orders to his commanders in systems distant from the galactic center , although not all obeyed , and the Galactic Alliance was often forced to continue hostilities against these reticent warriors . Once the transfer of the Yuuzhan Vong was complete , the living world engaged its hyperdrive and transported the species to the Unknown Regions . Although the caste clashed with the Extolled , the new name for the Shamed Ones , over their status in society , Nas Choka ' s warriors made progress in integrating themselves into a peaceful existence . Personality and traits . Nas Choka was principally a realist and a pragmatist , traits which set him apart from Tsavong Lah , his fanatical predecessor , and marked him as a formidable opponent of the leading Galactic Alliance military minds . Choka ' s sentiment that the pride of the Yuuzhan Vong warriors was dooming the war effort was innovative and forward - thinking ; as warmaster , Nas Choka recognized that a refusal to retreat or surrender , and a habit for expending resources fighting impossible battles for the sake of pride , would cost the Yuuzhan Vong their promised galaxy . While the warmaster recognized that surrender and retreat were anathema to the warriors , he understood that the war could not be won without some sacrifices being made by the Yuuzhan Vong . It was this same outlook on the true duty of the Yuuzhan Vong warrior which led Choka not to suicide in the final battle of the war , but to surrender and negotiation . Choka ' s realistic approach to warfare was also reflected in his dealings with his subordinates — when , during the Battle of Dac , his flagship ' s supreme commander began to exalt in the imminent defeat of the enemy , the irritated warmaster ordered him removed from the command chamber . Similarly , Choka was surprised when Centerpoint Station wiped out both his forces and those of the recently arrived Hapans , as he viewed such a sacrifice a savage and costly stratagem . Nas Choka proved his boldness as he openly warned against Shimrra ' s strategies concerning the strike on Dac , in a session of the Yuuzhan Vong Great Council , although he refrained from voicing his discontent with his superior ' s subsequent decision within Shimrra ' s citadel , as such talk could have led to his execution . Indeed , Choka was often forced to involve himself in court politics following his escalation , and was viewed by at least some to be shamelessly currying favor with the Supreme Overlord in his attempts to root out the heresy . The officer also often grew disgusted with the failure of his subordinates , such as that of Chine - kal , or the ambitions of others — Nom Anor and the intendant caste being the chief culprits of the trait , in Choka ' s eyes . The act of defection was also despised by Choka . The warmaster looked forward to a galaxy without vendetta or warfare , and saw it as his duty to defeat the Galactic Alliance while sparing the lives of as many Yuuzhan Vong as possible . During the Sekot Accords , Choka proclaimed that the Yuuzhan Vong warriors had only ever adhered to the practice of their caste . Choka was also extremely loyal to the Supreme Overlord who had guided the Yuuzhan Vong warriors from internecine strife to a promised galaxy . When Shimrra ordered the warmaster to assault Dac , Choka carried out the order and encouraged his subordinates to place their trust in the Supreme Overlord and the gods with whom he communicated . Nas Choka ' s total faith in Supreme Overlord Shimrra , however , was misplaced . At the time of the Jamaane coup , Shimrra deceived his followers by treating the rumors of Zonama Sekot as false , knowingly leading his species ' into a galaxy where the living world resided . Over fifty years later , Shimrra once again duped Choka into believing that Zonama Sekot ' s arrival in the Coruscant system was all part of a divine plan to test the Yuuzhan Vong . This belief led Choka to direct the majority of his forces against Zonama Sekot , trusting that once the living world was destroyed , the future of his species and the safety of Yuuzhan ' tar and the Supreme Overlord was assured . When this trust was proved wrong , Choka ' s faith was shattered and he lost all will to fight , surrendering the fate of his people to the Galactic Alliance at the Sekot Accords . Many of the warrior ' s strategies throughout the war were later regretful for Choka , as events beyond his control forced him to revise his plans . Tsavong Lah ' s strategies , while vital in winning half the galaxy for the Yuuzhan Vong , left the fleets overextended , forcing Choka to adopt a new approach to the war . B ' shith Vorrik ' s failure to crush the Imperial Remnant , and death at Esfandia , cost Choka ' s fleets dearly , as did the actions of the Galactic Alliance commander , Wedge Antilles , at Bilbringi . When the warmaster did go head to head against the Galactic Alliance military , he was able to mislead his opponents , such as at Fondor , Caluula and Toong ' l , or over Muscave . Choka ' s long campaign in Hutt Space won the entire territory for the Yuuzhan Vong , and his tenacity and commitment resulted in his escalation to the rank of warmaster ; a rank which the modest warrior believed he had not deserved . Despite his abilities in warfare , deception and divination , Choka ultimately failed to understand the true nature of his opponents . Viewing the Jedi Order as a race of warriors equal to those he commanded , the warmaster also expected mass execution or enslavement for the Yuuzhan Vong following the surrender , and the leniency he felt was being afforded to his species surprised him . Behind the scenes . Introduced at the end of James Luceno ' s " " , via a communications device , Choka was revealed to be a high - ranking Yuuzhan Vong military officer . The supreme commander appeared in the second installment of the " Agents of Chaos " duology and , while the narrative is never told from his point of view , acts as one of the principal Yuuzhan Vong characters . The Battle of Fondor sets up Choka ' s campaign against the Hutts , an event frequently referenced by other books in the long - running . Following " " , which saw the death of longtime Yuuzhan Vong antagonist Tsavong Lah , Choka returned to the forefront of the " New Jedi Order " , as the military leader of his species in " " and the series ' finale , " " . In " The Unifying Force " , once again written by Luceno , Choka had several scenes narrated from his perspective . In " The New Essential Chronology " , Nas Choka was referenced as a supreme commander during the Second Battle of Coruscant , despite his rank as warmaster . As " The New Essential Chronology " is also an in - universe document written by historian Voren Na ' al , this can be dismissed as a factual error both within and outside of the " Star Wars " universe . Similarly , " The New Essential Chronology " also places Choka in command of the forces that conquered Obroa - skai and other planets in the prelude to Tynna and Fondor , although " Agents of Chaos I : Hero ' s Trial " has Commander Tla as the warrior in charge . Nas Choka later received an entry in " The Complete Star Wars Encyclopedia " , published in 2008 . In this reference work , the date of Nas Choka ' s ascension to the rank of supreme commander was indicated to be 27 BBY , the year of Shimrra ' s coup . The " Complete Star Wars Encyclopedia " made an error , however , in stating that Choka became Supreme Overlord following Shimrra ' s death during the Second Battle of Coruscant . This directly contradicts the text of " The Unifying Force " . In " The Unifying Force " , Nas Choka ' s flagship is named " Yammka ' s Mount " , which is noted by Jaina Solo to be a newly - constructed vessel in appearance . In " Agents of Chaos II : Jedi Eclipse " , and " The Final Prophecy " , Nas Choka ' s flagship is stated to be " Yammka " , a much older vessel . In the " Unifying Force " , however , " Yammka ' s Mount " is referred to on occasion as " Yammka " . This article assumes that Nas Choka was provided with " Yammka ' s Mount " , a new flagship , during the events of " The Unifying Force " , and that it was referred to as " Yammka " as a contraction of its full name . Other than their names , therefore , the two vessels are not connected .
