Sian Jeisel Sian Jeisel was a female Devaronian Jedi Master who served the Jedi Order and the Galactic Republic during the final hours of the Republic Classic era . A dutiful Jedi , Jeisel felt that the Order should not have gotten involved in the Clone Wars , the major conflict between the Republic and the Confederacy of Independent Systems . Initially invoking her Right of Denial , Master Mace Windu eventually persuaded her to return to Coruscant and take up the rank of General within the Grand Army of the Republic . After three years of fighting valiantly , Jeisel ' s original misgivings about the war were found to be true ; the entire conflict was simply a trap for the Jedi , orchestrated by the elusive Dark Lord of the Sith , Darth Sidious . The leader of both sides , Sidious , in his alter ego Supreme Chancellor Palpatine , ordered the Republic Army to execute their Jedi leaders who had been branded as traitors to democracy . Caught unaware on Bogden 3 , Jeisel sacrificed herself in order to protect countless Jedi Initiate s fleeing the carnage . Biography . Early life . Most likely discovered at birth to be Force - sensitive on her homeworld of Devaron , Sian Jeisel was turned over to the Coruscant Jedi Temple for training in the ways of the Force . Entering into the academy there , Jeisel eventually went onto graduate and become apprenticed to a Jedi Master . Passing the Trials of Knighthood after years of study , the newly knighted Sian Jeisel continued independent study as a Guardian within the Order . Loyalty . Attaining the rank of Master after years of intensive study and work for the Jedi High Council , Jeisel was an active member of the Order when the conflict between the Republic and the Confederacy of Independent Systems erupted into all out war . Away from Coruscant at the time of the First Battle of Geonosis , Jeisel was disenchanted with the Republic , believing it too corrupt and not worthy enough for the Jedi to sacrifice their lives . Invoking her Right of Denial , Jeisel refused to answer the High Council ' s call to arms and instead remained abroad , gathering together with other like - minded Jedi . Initially , the High Council begrudgingly accepted this choice by a number of their ranks , but it soon became clear that if these members fell to the dark side of the Force , the ensuing schism would break the Order . Summoning representatives of each breakaway group to the estate of Jedi Master Sora Bulq on the moon Ruul , Master Mace Windu wished to open talks with each of the leaders and hoped to persuade them to join the war effort . Sian Jeisel responded to the summons , meeting with other dissident group leaders such as K ' Kruhk , Rhad Tarn , and Mira . While some members of the group were wary of Windu ' s impending visit , K ' Kruhk soothed their fears as Bulq and Windu began to discuss the terms of their return . However , unbeknownst to the dissident leaders , Sora Bulq had fallen to the dark side and was in league with Confederate leader Count Dooku . When the Dark Jedi Asajj Ventress attacked Bulq ' s estate per the Weequay ' s plan , the dissident Jedi engaged her in a fight . After killing Jedi Mira , Ventress seduced Jedi Tarn to the dark side . When Tarn turned his lightsaber on Jeisel , the Devaronian Jedi was forced to kill him in self defense . Convinced of Bulq ' s turn , both Jeisel and K ' Kruhk agreed to return with Master Windu to Coruscant , where they took up the rank of General within the Grand Army of the Republic . Siege of Saleucami . Marching onto many battlefronts , Master Jeisel was en route to Drongar when her troopship was boarded by Dooku ' s forces . When the Count himself stepped onto the bridge Jeisel , accompanied by Masters Tsui Choi and Kai Justiss , refused to fall for his merciful act even as they were spared the same death as the troops under their command . As the war dragged on , Jeisel found herself assigned to the campaign on Saleucami . Under the command of Councilor Oppo Rancisis , Jeisel proudly fought Morgukai clones during the five month engagement alongside fellow Jedi Knights Xiaan Amersu and Aayla Secura , as well as Masters K ' Kruhk and A ' Sharad Hett ; though she butted heads with Master Quinlan Vos , a Jedi she , as well as many in the Order , believed had fallen to the Separatists . Wary of Vos , she suspected he had a hand in the murder of Master Rancisis half way through the battle , though he proved to be loyal as he led the Republic to victory shortly there after . Order 66 . With the fires of battle dwindling on Saleucami , Jeisel and K ' Kruhk were reassigned to aid Master Ki - Adi - Mundi on Mygeeto . Taking off from the planet , their shuttle was damaged after a confrontation with a Separatist freighter and they were forced to limp to the Jedi academy on Bogden 3 to make repairs . As the clone troopers under their command refueled and repaired their shuttle , the two Jedi Masters were welcomed to the training facility by Master Du Mahn and the Jedi Initiate s of the Hawkbat Clan . While the Jedi and their troops relaxed in the academy ' s dining hall after a large feast , the clones received Order 66 from the Office of the Supreme Chancellor , an order which demanded all Jedi be killed . When her troops opened fire on the younglings , Jeisel sprung into action defending them , aiding the other Masters in cutting down the clones . After Master Mahn was killed , K ' Kruhk led a contingent of surviving students out the main hall to their repaired shuttle . As K ' Kruhk loaded the children on the ship , Jeisel remained in the main entrance of the facility , holding back the troopers ' advance . Realizing her only way to stop the clones was to bring down the building , Jeisel engaged one trooper in hand - to - hand combat , using the Force to detonate one of his thermal detonators and bring down the academy . Incinerated by the explosion , Jeisel ' s death was not in vain , as the surviving students were led to safety by her good friend Master K ' Kruhk , who shed a tear over her passing . Legacy . The younglings whom Jeisel saved would later escape alongside Master K ' Kruhk and Zao , and most lived for many years hidden from the Empire , learning the ways of the Force in peace . Reports of Master Jeisel ' s death inevitably reached the ears of Emperor Palpatine on Coruscant as he kept a record of each Jedi who died . Despite this , rumors circulated across the galaxy that she indeed lived on , working as a bounty hunter , jumping between the stars . This rumor made its way into Voren Na ' al ' s 35 ABY work , and was treated as fact as he detailed some of the Jedi who survived the initial stages of the Great Jedi Purge . Personality and traits . Sian Jeisel was a loyal Jedi which earned her the respect of Asajj Ventress . However , Jeisel was initially reluctant to fight in the Clone Wars believing that the Republic was corrupt and the Jedi couldn ' t fight for it without corrupting themselves . Despite this , she was a skilled and brave warrior and was loyal to the Jedi Order . Jeisel appeared to share a close friendship with K ' Kruhk and saved him from Asajj Ventress during their encounter . She also highly respected Sora Bulq , before learning that he was a traitor to the Jedi Order , and believed that he was just as powerful as Mace Windu . Selfless as all good Jedi should be , Jeisel sacrificed herself during the first moments of Order 66 to allow K ' Kruhk and a group of Jedi Initiates to escape from their treacherous clone troopers . Powers and abilities . Sian Jeisel was a skilled warrior and her fighting prowess was respected by Mace Windu . She managed to slay the corrupt Rhad Tarn in a lightsaber duel . However , she was no match for the powerful Dark Acolyte Asajj Ventress , who was able to fend off her , Tarn , and K ' Kruhk simultaneously . Behind the scenes . Jeisel ' s first name was the result of a misunderstanding . Jan Duursema ' s daughter , Sian , dressed as Jeisel for Celebration III . A photograph of her from that event was captioned " Sian Jeisel " ; fans confused this as the character ' s full name , rather than the name of the person in the costume followed by what the costume portrayed . This confusion apparently led to " The New Essential Guide to Alien Species " using this name in text , making it official . Jeisel was originally described as a Jedi Purge survivor in " The New Essential Chronology " , but according to Randy Stradley , that information was based on a discarded story idea , and Jeisel ' s death in " " is now intended to be a final end for the character .
