Yun Yun , a Force - sensitive male Epicanthix , was the son of a wealthy mineral baron on Panatha . At a very young age , he became infatuated with Sariss , the Prophetess of the Church of the Dark Side . Following her teachings , he fell to the dark side of the Force and killed his own father . He later joined Jerec , the feared Dark Jedi and Inquisitor , and his band of Dark Jedi in the search for the Valley of the Jedi , a powerful Force nexus . In the city of Barons Hed on the planet Sulon , he dueled Kyle Katarn , a Jedi - in - training and the son of Morgan Katarn , the man who had discovered the valley and whose map Jerec used to locate it . Katarn defeated Yun but spared his life . When they met again near the valley , Katarn had been rendered unconscious by the crash of his ship . Sariss tried to kill the defenseless Katarn with her lightsaber , but Yun , remembering that Katarn had not killed him when he had the chance , blocked Sariss ' s blow . Deflected by that block , Sariss ' s blade accidentally hit Yun himself , mortally wounding him . Before dying , Yun could only say that the Jedi was worthy of defending himself in a battle . However , that last action redeemed Yun , and the young Epicanthix became one with the Force , seeing the bright light as he died . Indirectly , Yun continued to help Katarn even after his death ; it was Yun ' s lightsaber that Katarn used to defeat Jerec . Biography . Early life . Yun was a Force - sensitive Epicanthix male born in 17 BBY on the planet Panatha . The pampered son of a wealthy mineral baron , Yun had everything he wanted — as a result , he lacked patience and level - headedness . To develop such traits , which were needed in the family business , Yun was sent to the planet Bunduki around the year 3 ABY to learn from the ancient monk order known as the Followers of Palawa . However , after spending a year with them , he returned home , as the Palawa monks refused to teach him the secrets of the ancient martial art called Teräs Käsi , thinking him to be unprepared for such skills . Yun ' s father was disappointed , but he had another plan in mind . Seduced by the dark side . Yun ' s father decided that his son should spend more time with the baron ' s fiancée , Sariss , the Prophetess of the Church of the Dark Side . Soon , Yun started learning the secrets of the dark side of the Force from Sariss . While listening to her teachings , Yun eventually fell in love with the Prophetess . Sariss , realizing this , seduced Yun , but she told him that they could not be together because of Sariss ' s vow to Yun ' s father . Manipulated by the Prophetess , Yun killed his own father and succumbed to the dark side . He then apparently abandoned , if not killed , his mother and sister . After that , Yun pledged his family ' s assets to Sariss ' s Master , the Miraluka Dark Jedi Jerec , and joined Jerec ' s cadre of Dark Jedi . Besides Sariss and Jerec himself , the cadre included the former Jedi Maw , the insane Twi ' lek Boc Aseca , and the Sithspawn Gorc and Pic , also known as the Brothers of the Sith . Yun then constructed his own yellow - bladed lightsaber . Serving under Jerec and participating in many senseless slayings , Yun became very cold - blooded , with killing becoming normal for him . However , he soon noticed that Sariss was not responding to his feelings and began experiencing countless nightmares in which he killed many people . Yun started to doubt if his actions were right , but Sariss suppressed such thoughts in her apprentice . Soon , egged on by the Prophetess , Yun decided to wreak vengeance on his Palawan masters . He took a squad of stormtroopers and his comrade Dark Jedi to Bunduki , where he killed his former teachers . On Bunduki , during the height of the carnage that Yun had started , his men met the twenty - five - thousand - year - old master of Teräs Käsi , ex - Emperor ' s Hand Arden Lyn . Search for the Valley of the Jedi . With the death of Emperor Palpatine in 4 ABY , Jerec started thinking of plans to rebuild the collapsing Empire , with himself as the new Emperor . In order for his plans to come to fruition , however , he needed the power of the Valley of the Jedi , a Force nexus formed in the final battle of the New Sith Wars more than a thousand years ago . The souls of numerous Jedi and Sith were trapped in the valley as a result of the explosion of the thought bomb , a powerful weapon detonated by Lord Kaan , one of the last leaders of the Sith during that period . If Jerec could control the essence of the valley , he would possess the great power that he felt he needed to achieve his goals . As one of his servants , Yun helped the Miraluka Dark Jedi in his quest . Somehow , Jerec learned that a Jedi called Qu Rahn might have known the location of the valley . In 5 ABY The Miraluka tracked Rahn to the planet Dorlo and ordered his capture . Yun , Sariss , and Maw led the landing party , which consisted of two skimmer s . However , their prey evaded them , destroying both skimmers in the process , and escaped from the planet on a CR90 corvette . Rahn and his Rebel companions — the young pilot called Duno Dree , the Klatooinian technologist Rolanda Gron and the linguistics expert Nij Por Ral — however , could not escape from Jerec ' s Super Star Destroyer , the " Vengeance " , and soon they were captured and brought aboard . Rahn and the Rebels were then interrogated . Each time Rahn refused to answer the question Jerec asked him , the Miraluka ordered his Dark Jedi to kill one of Rahn ' s men , with Yun being instructed to kill Nij Por Ral . Before doing so , the young darksider asked Rahn about the location of the valley himself . Rahn refused to answer , again , and Yun struck Por Ral with his lightsaber . However , he accidentally hit the linguist ' s shoulder . Embarrassed by his failure to make a clean kill , Yun struck once again , this time killing the Rebel . Eventually , Rahn was left alone . He tried to provoke Jerec into killing him , but Jerec probed his mind instead and discovered that although Qu Rahn did not know the location of the valley , his friend Morgan Katarn , killed by Jerec several years ago , did and had kept the map leading to it in his home on the planet Sulon . Realizing that Jerec had learned his secret , Rahn , using the Force , stole Yun ' s lightsaber from the youth ' s belt and attacked the Dark Jedi . Having lost his weapon , Yun barely avoided Rahn ' s blow and then could only watch as the Jedi Master easily dealt with the far more experienced Boc , Sariss , Maw , and Gorc , one by one , until Jerec intervened and killed Rahn . Jerec then sent Yun , along with the other Dark Jedi , to Sulon to assist the droid information broker 8t88 , whom Jerec hired to find and decode Katarn ' s map . The droid succeeded and found the map embedded on the ceiling of the Katarn homestead . He then took it to the Government House located in the city of Barons Hed , where he deciphered it and sent a digital copy to Jerec . However , at that moment the son of Morgan Katarn and an aspiring Jedi , Kyle Katarn , who was trying to stop Jerec , appeared in the tower and started asking 8t88 about the map . Yun , who was ordered by Jerec to destroy the stone map , took it upon himself to protect the secret of the valley ' s location from Katarn . Yun rode an elevator down from the roof of the tower and destroyed the map , creating a distraction that allowed 8t88 to escape . Yun then used Force Destruction to knock Katarn into the wall , threw his blaster away with the Force , and mocked him , forcing the Jedi into a duel . However , the inexperienced Yun was quickly defeated by Katarn , who had a lightsaber of his own . The duel ended when Katarn struck Yun on the arm . Defeated , the young Dark Jedi told Katarn to kill him , but the latter spared the youth ' s life . Surprised and feeling that something was right in Katarn ' s action at the same time , Yun used the Force to retrieve his lightsaber , which he had lost during the duel , and escaped the tower by levitating through the roof . Rejoining his dark side comrades , Yun traveled along with the rest of Jerec ' s forces to Ruusan , the planet where the Valley of the Jedi was located . There , they discovered a settlement called " Fort Nowhere " . Yun , Boc , and Sariss were sent there under the guise of parlaying with the locals , while their real intent was to learn if the people who lived in the fort knew about the valley ' s location . While Sariss " negotiated " with Mayor Byron Devo III , Yun and Boc looked around the fort . They eventually discovered that the fort - dwellers had no knowledge of the valley and , upon hearing that , Jerec ordered them to destroy the settlement . Soon , a battle broke out on the planet . Commanded by Sariss , the Imperial forces captured or killed almost all of the people from the fort , though some managed to escape . Yun participated in the battle and at its end , he was given the task of destroying the colonists ' subsurface farms , after which he returned to the " Vengeance " . Aboard the " Vengeance " , Yun once again began having dreams of himself killing many people , including his father , mother , and sister , as well as of his failure to kill Nij Por Ral with one strike . Those dreams had been following him for a long time and in them , Yun ' s lightsaber was transformed into an ancient - styled sword , with which he cut off heads of his relatives . The dreams once again raised questions in Yun about his path . After waking up in horror from one such dream , Yun was approached by Boc , who said that Jerec needed him . Eager to help his Master , Yun was very disappointed when Jerec revealed that his task was to oversee the excavation works at the valley ' s caves filled with artifacts . Specifically , Yun was assigned to assist Major Vig in getting rid of the spirits of the Jedi and Sith that scared the stormtroopers and halted the operation . However , Jerec took the young Dark Jedi to the planet in his personal ship , telling Yun many amusing stories along the way and leaving him with a sense of significance . Following this trip , all Yun ' s doubts and frustrations temporarily faded away . When Yun reached the caves , he saw the stormtroopers running in panic from the spirits , or " screamers " as Jerec ' s troops had dubbed them . Yun tried to defeat the spirits by shaping the Force and hurling it towards them , but this tactic did not work . Suddenly , he heard a strange voice in his head . Not realizing at first who was talking to him , Yun listened as that voice told him to think about the extent to which the spirits had suffered in order to make them go away . Successfully eradicating several spirits this way and taking a tour of the ancient storerooms filled with treasure , Yun listened as the same voice , which he finally recognized as Qu Rahn ' s , told him that the fate of billions of lives were dependent on the events that would take place on Ruusan and that Yun would play an important part in it . Yun asked what kind of part , but was told that " that " was entirely up to himself . Rahn also informed Yun that , deep inside of him , the light side of the Force was still present ; it was weak , but it was there . Redemption . Days later , the Imperial forces on Ruusan experienced a worldquake which caused a large piece of rock to fall on top of an Imperial called Jaru . Under the influence of the light side , Yun used the Force to lift the rock from Jaru , thus saving his life , despite not lifting anything of such size during the training under Jerec and Sariss . After that event , Rahn briefly contacted him again , telling him that the dark side was not the only source of power . Yun thought on Rahn ' s words , and later that night , he slept well for the first time with a smile on his face . After that event , something changed inside of Yun — a fact that did not escape Sariss ' s eyes , though she did not understand what the reason was . A short time later , Yun was called by Sariss , who told him that Jerec acknowledged that Yun did well with the rock . Despite being driven closer to the light side of the Force , Yun was still pleased with such words . Sariss then gave Yun his next assignment — to find out what happened to Patrol Zulu , Able , Mary 341 , which was long overdue . His previous task having been given to Boc , Yun took an AT - AT and an AT - ST and set off on the mission . Remembering that the men of Lieutenant Aagon , the commanding officer of the patrol , had the dead bodies of Ruusan ' s native Bouncer species hanging over their bunks , Yun turned his squad to the north , where the Bouncers were rumored to live . There , he felt Katarn ' s presence in the Force . While he had the chance to report everything he knew , Yun chose not to as an act of repaying his debt to Katarn . Yun said to himself that he would spare Katarn ' s life just as Katarn had spared Yun ' s , and ordered his troops to continue north . Yun later accompanied Jerec when the Dark Jedi Master confronted Katarn , who was furious after killing Maw on a landing pad near Jerec ' s personal cargo ship , the " Sulon Star " . Jerec tried to turn Katarn to the dark side by persuading him to kill his partner and love , Jan Ors , whom Jerec ' s men had captured earlier . Katarn managed to hold off his anger and stay with the light , and Yun watched as his Master pushed the Jedi into the " Sulon Star " and then sent the doomed ship towards the surface . Katarn managed to escape from the " Sulon Star " in his own ship , the " Moldy Crow " , though he crashed the vessel in the process . He was later found unconscious by Yun , Boc and Sariss . Boc destroyed Katarn ' s lightsaber before leaving to assist Jerec in the valley . Sariss then attempted to execute Katarn with her lightsaber ; but Yun , whose body seemed to act on its own , blocked Sariss ' s blow , which accidentally deflected against him , inflicting a mortal wound . Before dying , Yun told Sariss that Katarn , as a Jedi , did not deserve to be executed , but instead should be granted a battle . Seeing a bright light before his eyes , Yun was redeemed and returned to the light side before he drew his final breath . Legacy . Katarn , having lost his lightsaber , took up the fallen Dark Jedi ' s lightsaber in order to defend himself from Sariss , whom he eventually slew . With Yun and Sariss dead and Maw , Gorc , and Pic all killed by Katarn earlier , Boc and Jerec were left as the only living members of Jerec ' s Dark Jedi cadre . Using Yun ' s saber , Katarn descended further into the valley and killed them as well . Ultimately , Yun had played his part , indirectly saving billions of lives , as predicted by Rahn . By blocking Sariss ' s blow , he had saved Kyle Katarn , enabling him to locate the Valley of the Jedi , slay Jerec , and save the galaxy . Following the death of Jerec , Katarn continued to use Yun ' s lightsaber for several more years and used it to duel his former apprentice Mara Jade when he was corrupted by the dark side until he eventually constructed his own . Personality and traits . Being only twenty - two years old , Yun was very brash , impatient and always wanted to prove himself to his Masters , especially Sariss , whom he truly and deeply loved . Because of such an attitude , he was considered the most wild of Jerec ' s cadre . One of Yun ' s ways of showing his worthiness was the participation in many slayings . Killing became normal for Yun , and he eventually found out that he wanted more . However , he soon realized that Sariss was not responding to his feelings , as she in fact considered him no more than a son . Yun then started to doubt if being beside his love was worth the price he had paid for it . Such thoughts were eventually suppressed by Sariss , but Yun still questioned the righteousness of his path several more times , although in some moments — like when Jerec took him down to Ruusan aboard his personal ship — all doubts disappeared and the price seemed worth paying for a moment . Yun was severely worried with the amount of stormtrooper casualties during the battle of Fort Nowhere , until Sariss assured him that that was what they were paid for and asked Yun to be less sensitive . However , when Yun saw that stormtroopers were scared by the ghosts of the Jedi , he asked Major Vig to execute several of them . Vig refused and Yun found his method of compassion " interesting . " Qu Rahn provided a final catalyst for Yun to make a long chain of seemingly minor decisions , which , when taken together , formed one important decision — to save Katarn , even though at the moment he blocked Sariss ' s blow , Yun did not fully understand when and how he decided to do that ; he only felt himself respond . He only seemed to realize why he saved the Jedi after Sariss struck him with her lightsaber . Yun also developed a unique attitude towards his fellow Dark Jedi . For instance , he found Maw ' s talent to sense fear distasteful , likening him to a Nek battle dog sniffing its prey . Yun himself preferred more elegant demonstrations of power . In turn , he thought that Jerec had many unpleasant qualities , but could be very charming when he chose to , and enjoyed being in Jerec ' s company . He basked in the glory reflected from his Master , when stormtroopers jumped out of the way and officers came to attention upon seeing him . Yun was a light - skinned man with black hair and dark brown eyes . Powers and abilities . Despite being the newest addition to Jerec ' s Dark Jedi and spending only a year with them , Yun became a skilled Force - user , although he mostly used non aggressive Force powers . He was especially adept at telekinesis , as indicated by his ability to Force - throw Katarn ' s blaster and then to levitate through the roof after his duel with the Jedi while summoning his lightsaber at the same time . As a subtle demonstration of his powers , he was able to make the skimmer ' s slipstream avoid his carefully combed hair and to lead the helmsman into believing that his body was itching . Yun ' s telekinetic powers seemed to increase even more when he tried to lift the rock the size of a hovercraft from Jaru , not thinking about the dark side at all . Yun ' s Force sense ability was less developed and sometimes failed him . He was unable to sense Sariss approaching him on Sulon , although he later sensed Katarn ' s presence on Ruusan . In addition to Force sense and telekinesis , Yun was also a practitioner of Force speed , Force blinding , Force Jump and various incarnations of Mind trick , including Force Persuasion . Yun ' s most notable offensive power was a somewhat weaker version of Force Destruction , which he used to attack Katarn . Instead of killing Katarn instantly or draining all his powers as Destruction usually did , Yun ' s attack only threw the Jedi into the wall . While on Ruusan , Yun also tried to defeat ghosts of the Jedi and Sith with the Force , by shaping it and hurling it towards them , before trying another tactic suggested by the spirit of Rahn — to sense their pain . Yun could read , write and speak two languages , his native Epicant and the widespread Basic . He was proficient with blaster pistols and some other simple weapons . He also managed to build his own lightsaber , which was a unique weapon . It came equipped with a so - called " modified pistol grip " — meaning that carefully cast projections echoed the Human hand and gave his index finger a place to rest . Not only that , but the grip was made from a highly malleable " live " polymer that explored the user ' s hand and morphed into a solid , highly customized grip . When Katarn took the lightsaber , he immediately fell in love with it . Yun ' s skill with the lightsaber was not as good , however , as shown by the fact that he was defeated by Katarn , who had acquired his own lightsaber only hours before their duel ; and by Yun ' s failure to kill Por Ral with one strike . Behind the scenes . Yun ' s first appearance was in " " , a first - person shooter video game released on October 9 , 1997 , by LucasArts . In the game , Yun serves as one of the main character ' s antagonists , who ultimately saves the main hero . In the live action cutscenes of the game , Yun was portrayed by Rafer Weigel , who also provided his voice for Yun ' s CGI appearances . Yun later appeared in " " and " " , the 1998 novella adaptations of the game , as well as in the and the , which , in turn , adapted the novels into an audio drama in which Yun was voiced by Timothy Kuhlmann . Yun ' s backstory was later expanded in " The Dark Forces Saga " , a series of game scenarios released by Wizards of the Coast on their web site . Also , Yun was briefly mentioned in Jerec ' s and Katarn ' s entries of " The New Essential Guide to Characters " and received an entry in " The Complete Star Wars Encyclopedia " . Yun is also a playable character in the multiplayer feature of both " Star Wars : Jedi Knight : Dark Forces II " and its add - on " " . Yun ' s likeness was also used in " Mysteries of the Sith " to represent a type of statue which the player encounters in the last two levels of the game . Non - canonical death . In the non - canon ical ending of " Dark Forces II " , where Kyle Katarn has chosen the dark side , Yun , not impressed with his choice , remains on the dark side as well . He is then sent to stop Katarn from reaching the valley and claiming it for his own needs . Yun faces Katarn , who in that case does not crash the " Moldy Crow " , near the crash site of the " Sulon Star " . There , Katarn corrects his " earlier mistake " and kills Yun . Differences between versions . Yun ' s death is shown slightly different in " Star Wars : Jedi Knight : Dark Forces II " , " Dark Forces : Jedi Knight " , and the " Dark Forces : Jedi Knight " audio drama . In the game , he blocks Sariss ' s blow , and she accidentally deflects her lightsaber into Yun . Before dying Yun tells her that Katarn is a Jedi and deserves a battle . In the novella , Yun hits Sariss in the arm and she instinctively strikes him in self - defense . In the audio version , Yun blocks Sariss ' s blow and tells her that he will not allow her to kill Katarn . He informs Sariss that something has opened his eyes and he knows that there is a better way . Sariss responds that there is one , but Yun won ' t live to see it , and deliberately strikes him . Sariss ' s action angers Katarn . He picks up Yun ' s saber and attacks Sariss . After Katarn kills Sariss , he checks Yun , who , surprisingly , is still breathing . Yun tells Katarn that he is " fading into the Force " and that he has learned compassion , before passing away . Yun ' s words before the duel with Katarn also change between the game , the novel , and the audio adaptation . In the game and the novel he says a single line , although it differs between the sources . In the audio drama , Yun and Katarn engage in a much longer dialogue that continues throughout their fight . The audio drama dialogue is notable for including the line : " You are quicker than I thought " — a taunt that Yun actually uses during his duel with Katarn in the game . Additionally , the " Dark Forces : Rebel Agent " audio drama omits the scene of Nij Por Ral ' s execution and Rahn ' s subsequent attack on the Dark Jedi .
