Bpfassh Uprising The Bpfassh Uprising was a Dark Jedi insurrection that wreaked havoc in the Sluis sector in 19 . 75 BBY , while the Clone Wars were drawing to a close . It started when a group of Jedi from the planet of Bpfassh fell to the dark side of the Force due to the pressure of the war . To oppose them , the Jedi High Council formed a task force led by Yoda , the Grand Master of the Jedi Order himself . Thanks to his intervention , the insurrection was quelled , marking one of the first major victories of the Galactic Republic in the third year of the Clone Wars . The Dark Jedi from Bpfassh , however , had not spoken their last word . In 19 BBY , the Clone Wars concluded , and the despotic Galactic Empire was formed . Shortly afterwards , the Bpfasshi Dark Jedi resumed their attacks in the Sluis sector , engaging in a large space battle . At the end of that battle , the last of the Dark Jedi seized the ship of the smuggler Jorj Car ' das ship and took it to Dagobah . Ironically , that planet was the new residence of Yoda , who was hiding from the Jedi - hating Empire . Once again , the Bpfasshi darksider was killed by the Grand Master . Despite Yoda ' s victory , the Bpfassh Uprising was best remembered as a fiasco . Many years after the events , the Bpfasshi still had a deep - seated resentment against the Jedi , and the incident was still discussed in the Imperial Senate . Prelude . In the last decades of the Galactic Republic , the planet of Bpfassh in the Sluis sector hosted a satellite training facility of the Jedi Order . However , that chapter house had a long history of rebelliousness to the High Council , the governing body of the Order . In the third month of the year 13 post - Great ReSynchronization , the Sluis sector officially seceded from the Republic to join the Confederacy of Independent Systems . A few months later , the Clone Wars broke out between the Republic and the separatist Confederacy . Due to their superior combat experience , the Jedi were led to play a pivotal part in the conflict , becoming the generals and commanders of the new clone army of the Republic . However , there were Jedi who doubted the war and refused to receive their martial promotion from the High Council . Those dissidents formed an informal movement that was also joined by those who invoked the Right of Denial , a tradition that allowed Jedi to protest against a decision made by the High Council . The whole Jedi academy of Bpfassh ended up joining the movement too . The uprising . Initial insurrection . As the Clone Wars went on , the Sluis sector went trough continual fighting . Because of its affiliation with the Confederacy of Independent Systems , the sector was being pressured by the Republic forces based on Eriadu , in the neighboring Seswenna sector . Additionally , the Sons and Daughters of Freedom , a crew of Republic privateers led by Zozridor Slayke , kept raiding the sector . Ultimately , that situation provoked a spike of martial zealotry among the Jedi of the Bpfassh academy . Although they had initially refused to get involved in the ongoing conflict , the Bpfasshi Jedi gave in to their anger and fell to the dark side of the Force . They set themselves against Slayke ' s men and were responsible for a rampage of terror and destruction throughout the Sluis sector . Eventually , the High Council sent a task force of loyal Jedi to quell the Bpfassh uprising . Yoda , the Grand Master of the Jedi Order himself , was part of that force . At one point , Yoda was pitted against at least three adversaries armed with lightsabers . The Jedi Knight Ylenic It ' kla was also part of the Jedi task force , and so was Nejaa Halcyon , a Corellian Jedi who had already fought in the Sluis sector in 22 BBY . The latter in particular was instrumental in putting down the uprising , although the details of his involvement would be lost in the mists of time . Eventually , Grand Master Yoda dueled the leader of the Dark Jedi and defeated him . Post - Clone Wars resumption . A few months later , Supreme Chancellor Palpatine of the Galactic Republic , who was secretly a Sith Lord named Darth Sidious , revealed his true colors to the galaxy . As the Clone Wars were brought to an end , the Republic was replaced by a tyrannical Galactic Empire led by Sidious himself . As the Empire sought to exterminate all Jedi , Yoda , the former victor of the Bpfassh Uprising , retreated to a self - imposed exile on Dagobah , a swamp planet of the Sluis sector . At that time , however , the sector in question experienced a resurgence of Bpfasshi Dark Jedi activity , despite Yoda ' s earlier victory over their leader . At some point , a large space battle erupted between the darksiders and the combined forces of everyone else in the sector . A smuggler named Jorj Car ' das , who ran the former business of one Booster Terrik , was accidentally caught up in the middle of the fray . As the space battle drew to a close at the darksiders ' expense , one of the most powerful of the Dark Jedi captured Car ' das ' vessel , forcing the smuggler and his four crewmen to take off . He immediately killed one of Car ' das ' men by tearing his body apart , and turning the other three into mind - controlled puppets . However , the Dark Jedi left the smuggler captain himself mostly alone , presumably as the darksider needed Car ' das ' knowledge of ports and hyperlanes to make his escape . The Dark Jedi demanded passage to Dagobah , either seeking sanctuary or Yoda ' s hiding place . As soon as Car ' das put down his ship at the edge of Dagobah clearing , Yoda himself made an appearance , as if he had been expecting a dark visitor . The resulting battle between the two Force - users lasted nearly one day and a half , during which , according to Car ' das , " the swamp blazed with fire and lightning . " Eventually , Yoda got the upper hand . The Dark Jedi perished , disintegrating in a burst of energy . Car ' das and what was left of his men had also taken part in the fighting , but only the smuggler had survived . Yoda then healed the wounded man and sent him on his way . The death of the Bpfasshi Dark Jedi left a lasting stain on Dagbobah , which further helped Yoda to hide himself from the Imperials . Aftermath . Following the chaos of the Clone Wars and the rise of Palpatine ' s Empire , many historical records were either destroyed or tampered with . Historians still knew that the Jedi task force had succeeded in their mission and that the last Dark Jedi had made his or her way to Dagobah , but they surmised that the darksider had been destroyed either by the natural hazards of the swamp planet or by Halcyon and his men . Additionally , the Bpfassh Uprising was conflated with that of a similar event that had involved Master Jorus C ' baoth . Indeed , when Luke Skywalker , the first of a new generation of Jedi , searched the Galactic Senate ' s records on Jorus C ' baoth in 9 ABY , he read that C ' baoth had fought the Dark Jedi on Bpfassh , while he had in fact defeated darksiders in the Elrood sector at some point before the Battle of Naboo . However , Jorj Car ' das was still alive , and could testify on Yoda ' s decisive involvement . By 19 ABY , he had told his story to at least two individuals — Talon Karrde and Shada D ' ukal . Although the Bpfassh Uprising had been efficiently brought to an end , the inhabitants of Bpfassh remained wary of all Jedi . Many years later , echoes of the incident were still heard in the Imperial Senate , the ruling council of the Galactic Empire . In 9 ABY , nearly three decades after the events , the former Imperial senator Leia Organa Solo still remembered what she had heard about the Bpfasshi fiasco during her years of service . Behind the scenes . Origin . The Bpfasshi insurrection was first mentioned in " Heir to the Empire " , a 1991 novel and the first entry in Timothy Zahn ' s so - called " " . In the novel , Luke Skywalker is advised to stay away from Bpfassh , as some of that its Jedi " went bad " during the Clone Wars , leading to resentment toward their order . Skywalker also learns that the cave in which he confronted a vision of his father was first tainted with dark energies years before , when Yoda killed a powerful Bpfasshi Dark Jedi on Dagobah during the Clone Wars . According to Princess Leia , that duel must have occurred thirty to thirty - five years before the novel ' s present time , which would put it between 26 and 21 BBY . In " Dark Force Rising " , the second entry in the " Thrawn Trilogy " , it was mentioned that Jorus C ' baoth was part of a taskforce assembled to oppose a Dark Jedi insurrection on Bpfassh . In 1997 and 1998 , Zahn published " The Hand of Thrawn Duology " . In the series ' second an final tome , titled " Vision of the Future " , readers were told how the smuggler Jorj Car ' das was kidnapped by a Dark Jedi who took him Dagobah , where the darksider got beaten by Yoda . According to Talon Karrde , those events took place 45 years before the novel ' s present time , which would still be 26 BBY . Retcons . With the release of the prequel trilogy between 1999 and 2005 , the course of ancient events invented by Zahn for his trilogy was compromised . Initially , the Clone Wars were supposed to have taken place thirty - five years before , but the prequels showed they only started in 22 BBY and ended in 19 BBY . Because of that , all the dates featured in the " Thrawn Trilogy " are off by sixteen years . In " The Official Star Wars Fact File " , a 140 - issue magazine published from 2002 to 2005 , two conflicting account of the Bpfasshi Uprising ' s endgame were given . According to the 28th issue , the death of the Dark Jedi leader was thought to have been caused by either the natural hazards of Dagobah or a Jedi task force led by Nejaa Halcyon and Ylenic It ' kla . Despite that , the 86th issue of the " Fact File " confirmed Yoda ' s responsibilities in the darksider ' s demise . — while also mentioning Halcyon ' s participation in the mission . However , the " Official Fact File " were meant to be the real - life equivalent of a centralized database created by the New Republic in 27 ABY , which implies it may contain inaccuracies from an in - universe point of view . Incidentally , the 28th issue does state that many historical records were either altered or lost following Palpatine ' s rise to Emperor , and presents its information as surmises . Morever , the script of the 2005 movie specified that Yoda had never been on Dagobah before his exile at the end of the Clone Wars . The reference book " The New Essential Chronology " , which was released a few months after the movie , included a retelling of the Bpfassh insurrection . While omitting the problematic endgame on Dagobah , that new account established a connection between the uprising and the Jedi dissident movement that appeared in other sources such as " " . In 2008 , the canonicity of the Bpfasshi uprising was brought up in the 98th issue of the " Star Wars Insider " magazine . Lucasfilm official Leland Chee stated that Yoda ' s battle against a Bpfasshi Dark Jedi as described in Zahn ' s novel was no longer part of continuity . However , Chee said that " a mortally wounded darksider made it to Dagobah after a confrontation with Yoda , but the battle did not take place there . " The problem was solved a few months later , when the roleplaying game sourcebook " Scum and Villainy " retconned the incident with Car ' das , the Dark Jedi and Yoda to have happened " after " the Clone Wars . Since they do not contradict each other , the present article considers that Yoda fought Bpfasshi Dark Jedi both during and after the Clone Wars .
