Ahsi Yim Ahsi Yim was a female Yuuzhan Vong and a member of the species ' shaper caste , who experimented with the science of biotechnology to aid the Yuuzhan Vong warriors in their conquests . Yim served during the Yuuzhan Vong War , in which her race invaded a galaxy in order to conquer its worlds and convert its inhabitants to the Yuuzhan Vong religion . Following the conquest of the planet Duro , Ahsi Yim worked on the terraforming of the world . The shaper found , however , that the orthodox protocols that governed her caste were severely outmoded and lacking when it came to the task at hand . Rather than slavishly obey the strictures , Ahsi Yim practiced heresy by adapting the protocols to suit the needs of the assignment . With her methods undiscovered and her success lauded , Yim was escalated to the rank of master shaper in 28 ABY and assigned to the conquered capital world of the New Republic , Coruscant . Yim worked on the terraforming of the world as she had on Duro , but soon found herself confronted with the same problems and once again secretly turned to heresy . Ahsi Yim ' s heresy was discovered , but instead of being sacrificed to the Yuuzhan Vong gods , the master shaper was secretly allowed to join a team of shapers , clandestinely overseen by Supreme Overlord Shimrra himself , which had been tasked with creating new technology — through heresy if need be — to aid in the continued conquest of the galaxy . Ahsi Yim worked alongside her sister Nen Yim ; at the same time , the master shaper maintained ties with the Quorealist s , an organization of Yuuzhan Vong opposed to Shimrra who operated on Coruscant . Due to Ahsi Yim ' s connections , she was approached by her sister in 29 ABY , who asked the master shaper if she could facilitate a meeting with a Quorealist . Yim was able to carry out her sister ' s request , although Nen Yim was abducted from the compound shortly after her meeting with the Quorealist , and Ahsi Yim was executed when a rumor reached Supreme Overlord Shimrra that she had played a part in the kidnapping . Biography . Heretic shaper . A member of the Yuuzhan Vong species , Ahsi Yim was trained as a shaper , a Yuuzhan Vong scientist who manipulated the biological technology of her race in the interests of its preservation and survival . The Yuuzhan Vong traveled over many millennia to another galaxy , in the belief that it was their new home following years roaming the Intergalactic Void . Yim , like all Yuuzhan Vong , was encouraged to believe that the species ' gods had granted the new galaxy to their worshipers . The invasion of the galaxy proceeded well and Ahsi Yim was tasked to the terraforming of the conquered planet Duro , which was captured from the defending New Republic in 26 ABY . Duro , a planet poisoned by centuries of technological excess , was targeted to be remade as a verdant paradise . While working on the terraforming of Duro , however , Yim began to discover that the shaping protocol s — strict orthodox instructions which governed the art of shaping — were lacking . Rather than adhere to the protocols as the shapers were ordered , Yim risked death as a heretic by undertaking her own research , adapting the protocols to suit the requirements of the task rather than attempting to work within the limits of orthodoxy . Yim ' s work went undiscovered ; due to the overall efforts of the shapers working to terraform the planet , Duro was successfully recreated as a world full of vegetation . A year following the conquest of Coruscant , the capital of the New Republic , Ahsi Yim was elevated to the rank of master shaper . She worked once again on the terraforming of a world — this time , it was Coruscant itself , which was to be remodeled in the image of the lost homeworld of the Yuuzhan Vong , Yuuzhan ' tar . Although Coruscant underwent vast changes , problems began occurring soon after its transformation . The dhuryam — a telepathic Yuuzhan Vong organism tasked with overseeing the newly anointed planet — began to compromise the terraforming process with a series of glitches . Ahsi Yim observed in frustration as the shapers responded with inhibited orthodox measures to counter the mistakes , which included an itching plague that infuriated the Yuuzhan Vong conquerors . The far - reaching problems led to the execution of Master Shaper Ch ' Gang Hool for his failure to resolve the issue . Ahsi Yim had already observed the adaptations of the galaxy ' s defenders to the Yuuzhan Vong invasion . Rather than remain committed to pre - existing technology , the inhabitants of the galaxy had adapted with new warships and tactics . Having experienced the conservatism of the shaper caste , Yim began to believe that the adaptation of the shaping protocols , despite its nature as arch - heresy in accordance with the stricture that only the god Yun - Yuuzhan could create new biotechnology , was the only way forward if the Yuuzhan Vong species was to be saved . She began to practice heresy on a larger scale , but was discovered . Rather than be executed , however , Ahsi Yim was taken to a secret compound on Coruscant , located within the confines of Supreme Overlord Shimrra ' s palace . There , she was allowed to continue to experiment with shaping technology under the auspices of her sister Nen Yim , who had been tasked by Shimrra with creating new technology to combat the galaxy ' s defenders . Ascension and death . Although Ahsi Yim was , due to her new assignment , in a position to aid her species in the conquest of their new galaxy , the master shaper retained her secrets . Yim had close ties to the Quorealist underground , a faction of dissident Yuuzhan Vong who were opposed to Shimrra and loyal to the Supreme Overlord ' s deceased predecessor , Quoreal . She was aware that the secret shaping laboratory in which she worked was proof that the orthodox shaping protocols had failed , and that Shimrra was concealing the truth from the Yuuzhan Vong . Furthermore , rumors were circling among Ahsi Yim ' s associates — rumors about a Yuuzhan Vong commander , Ekh ' m Val , who had made a chance discovery and lost his life when he reported it to Shimrra . The mysterious circumstances were further complicated by the fact that in 29 ABY , her sister Nen Yim was approached by Shimrra ' s familiar , Onimi , and given an object to study in great secrecy . Ahsi Yim was intrigued by the delivery ; a day later , she was summoned to Nen Yim ' s quarters . There , Ahsi Yim was soon made privy to her sister ' s secret . Nen Yim had been ordered to study a mysterious starship , which had a similar genotype to the living starships of the Yuuzhan Vong , and create weapons to deal with the biotechnology it utilized . The two master shapers discussed the reasons behind Shimrra ' s orders , which involved the legend of a living planet , Zonama Sekot , which had been sighted in the galaxy by Ekh ' m Val , who had subsequently been killed by Shimrra for his discovery . Ahsi Yim and her sister agreed that it seemed likely that while Shimrra wished to deny the existence of Zonama Sekot to the rest of the Yuuzhan Vong , due to the danger it seemingly posed to the species , the Supreme Overlord was preparing for a military strike on the world . The lack of pertinent information , however , led to Nen Yim ' s request that Ahsi secure a meeting with someone who possessed knowledge of Zonama Sekot — someone who would not report the meeting to Shimrra . The master shaper realized that a Quorealist would be the ideal candidate , and arranged a meeting between Nen Yim and High Priest Harrar of Shimrra ' s court . Ahsi Yim continued with her work in the secret compound , only to be shocked one day when a pair of Jedi Knights infiltrated the laboratories with the help of rebel Shamed One s and kidnapped Nen Yim , before escaping aboard the mysterious starship . In the aftermath of Nen Yim ' s abduction , Ahsi Yim was promoted to the leader of the shaping project in her sister ' s stead . The position would be held by the master shaper only fleetingly , however . Shortly after Yim ' s ascension , she was executed on the orders of Supreme Overlord Shimrra . One of Yim ' s co - workers , Qelah Kwaad , had coveted the master shaper ' s position as project leader , and had deceived Shimrra into believing that Ahsi Yim had aided in Nen Yim ' s escape . Personality and traits . Ahsi Yim was a young , forward - thinking Yuuzhan Vong who was willing to risk death in order to aid her species ' continued survival . Rather than obey the strict shaping protocols , Yim clandestinely experimented with new technology . Skilled and talented in the execution of her duties , Yim was assigned to terraform two separate worlds and was promoted to the rank of master shaper for her efforts . Once Nen Yim had vanished from Coruscant , Ahsi Yim was the prime candidate for her sister ' s replacement . Shrewd and pragmatic , Ahsi Yim was able to comprehend that Yuuzhan Vong orthodoxy had failed the species . She had little trust in the gods or in Supreme Overlord Shimrra who , while embodying the species ' orthodoxy , was also secretly countermanding it . Yim maintained ties to dissident Yuuzhan Vong and was privy to much of the intrigue and gossip that circled the halls of power . Despite observing the flaws in the leadership and orthodoxy of her species , Yim ' s primary concern was with ensuring the survival of her race . Behind the scenes . Ahsi Yim was introduced as a minor Yuuzhan Vong character in Gregory Keyes ' " " . Although Keyes ' novel does not specifically state that Yim was executed , the " The Complete Star Wars Encyclopedia " , published in 2008 , established that this was indeed the case .
