Duel on Tython A lightsaber duel took place in 990 BBY between the surviving Dark Lord of the Sith Darth Bane and his apprentice Darth Zannah , against a group of five Jedi led by Lord Valenthyne Farfalla . After her escape from the Jedi Temple on Coruscant , Zannah arrived on the Deep Core world of Tython to warn Darth Bane of the Jedi ' s awareness of their existence and subsequent pursuit . The Sith barricaded themselves within the abandoned fortress of the long - dead Dark Lord Belia Darzu , in expectation of imminent combat with their enemies . Intent on the destruction of the last of the Sith , the Jedi descended upon Darzu ' s temple and engaged Darths Bane and Zannah in combat . Despite their strength in numbers , however , all five Jedi were slain by the two Sith , who proved stronger with both the lightsaber and in the Force . Prelude . Ten years after the destruction of the Sith Brotherhood of Darkness , a Force - sensitive young man named Darovit ventured to Coruscant to bring proof to the Jedi Council that Dark Lord of the Sith Darth Bane had survived the war ' s final battle . He was forestalled , however , when he unexpectedly sensed his cousin Zannah in the Jedi Temple Archives , just as the disguised Sith apprentice ' s false light - side aura wavered . Darovit had a sudden change of heart upon sight of her , and warned Zannah of the Jedi ' s intention to pursue her and her Master . Despite her resultant anger , Zannah quickly resumed her false aura and completed her research mission into the nature of orbalisk parasites for Darth Bane , who had become infested with them ten years prior . Zannah also learned of the healing abilities of Darovit , and resolved to exploit them in an attempt to free Bane of his orbalisk infestation . After they acquired an old hyperspace route to Tython from an Archive computer , Zannah quickly exited the Temple with Darovit in tow and left Coruscant aboard her personal starship , the " Loranda " . Elsewhere in the Jedi Temple , Jedi Johun Othone had gone in search of his former Master , Valenthyne Farfalla . Othone believed he had the necessary proof of the existence of the Sith , based on the testimony of Darovit , so he brought Darovit with him to Coruscant for a meeting with the Jedi Council . Othone finally caught up with Master Farfalla and explained the situation . They then proceeded to the Archives where Othone had left Darovit , only to find that the young man was no longer there . After some hasty investigating , the two Jedi discovered that Darovit had fled to Tython with Zannah . Armed with this knowledge , Farfalla then gathered a team of four Jedi : Raskta Lsu , Johun Othone , Sarro Xaj , and the Ithorian Master Worror . With Farfalla himself as the fifth , they left aboard Master Lsu ' s personal attack vessel , " Justice Crusader " . The Jedi arrived on Tython and landed their ship near the " Loranda " and Bane ' s ship , the " Mystic " , and entered the temple of the ancient Dark Lord Belia Darzu . There , the Jedi Masters and Knights immediately initiated combat against the two Sith Lords , Bane and Zannah . The duel . The room in which the duel took place was circular , with a door on either side . Empowered by Jedi Battle meditation , Farfalla and Lsu entered from one side while Othone and Xaj came in through the other . Their plan was to mount a two - pronged offensive , while simultaneously eliminating a potential escape by the Sith Lords . Worror entered last and behind the other Masters , focusing on his Battle meditation rather than actual combat . Upon seeing the Jedi , Bane rushed towards the Masters with his lightsaber drawn . His initial charge was met head - on by Raskta Lsu , Echani Jedi Weapon Master . She attacked Darth Bane but was unsuccessful in dealing any significant damage , thanks to the benefit of his orbalisk armor . As Bane charged towards her , Lsu evaded him , but then Bane ' s attention was drawn to Farfalla , who also had to dodge the Dark Lord ' s forward charge . Lsu again leaped towards Bane , only to be met with a powerful Force push that sent her flying across the room . Her saving grace was the Force barrier Farfalla threw up around her to cushion her impact . She was back on her feet , but Bane ' s attention was now on Farfalla . Bane unleashed a barrage of purple Sith lightning towards the Equine Jedi , but Farfalla again used a Force barrier to protect himself . The lightning tore right through the barrier but was intercepted and dispelled by Raskta Lsu . Bane audaciously charged again , and the Masters engaged him . While dueling , Bane elbowed Lsu in the ribs with enough strength to lift her off her feet and send her flying . The Echani woman was momentarily incapacitated , and Darth Bane finally engaged Farfalla . Lsu shouted to Farfalla to take heed of Bane ' s special lightsaber , which was giving his dueling style an unfamiliar advantage over them , but the sheer physical strength of Bane ' s next attack knocked Farfalla ' s lightsaber from his hand . He was saved again by Lsu , who managed to fell Bane with a scissor - kick from behind . When he recovered , Lsu directed her attacks at his face — the only exposed area of his body . Bane was losing ground as Farfalla tried to rejoin the duel , but Lsu saw him as a hindrance and so told him to hold back . Farfalla instead assisted his colleague by protecting her with another Force barrier . Meanwhile , Bane was being continuously backed up by Lsu . Then suddenly he disengaged her and raced towards the source of the Jedi ' s invigoration : Master Worror . Bane realized that Worror was supplementing the Jedi with his Battle meditation , and as Worror remained unprotected , Bane rushed him as fast as he could . Part two . On the opposite side of the room , Darth Zannah was holding her own against Sarro Xaj and Johun Othone . Xaj , a physically large Human male who also wielded a double - bladed lightsaber ( albeit much larger than Zannah ' s ) , hammered at her with brute strength , causing her to lose her footing . However , Othone ' s Niman style served to disrupt Xaj ' s assault , thereby assisting Zannah in regaining her composure . Zannah was acquainted with a purely offensive style of Djem So , having only learned to defend herself against her Master , who had little need for defense due to his resident symbiosis . She was unprepared for an opponent who incorporated defensive maneuvers into his fighting style , and Sarro Xaj ' s polished and refined technique threw her off her guard . On several occasions , Xaj ' s strength overwhelmed Zannah ' s defenses , though not to the point of her being unable to fight . His ferocity was balanced by the awkward rhythm with which Othone dueled . Because of Othone ' s unpolished style , Xaj was forced to minimize his own assault to avoid striking his partner . This disruption gave Zannah the opportunity to resume her cadence and erect her impenetrable wall of defense yet again . An opportunity arose to cut Othone down , but Zannah declined , foreseeing and instead allowing him to be more of a hindrance to his colleagues than her . Nimbly she danced around her assailants , giving ground and regaining strength as they advanced . Suddenly the Knights were beckoned by Farfalla ; realizing Bane ' s near invulnerability , the Equine Jedi called for help , which Othone willingly gave . He reacted immediately by leaping over towards the Masters and joining the battle at the same time as Farfalla . With his attackers now three Jedi strong , Darth Bane was actually being held steady , so much so that he was forced to assume a defensive position . With Othone on his right and Farfalla on the left , Raskta Lsu attacked the Dark Lord from the middle , all the while playing off the clumsiness of Othone and the gracefulness of Farfalla . Lsu ' s skill was such that she was actually benefiting from the hindrance Othone had previously been to Sarro Xaj . But for all the strength in their attack , the Jedi could neither subdue nor defeat Bane . Othone caught a glimpse of Bane ' s wrist between the shells of the orbalisk armor and aimed his next strike there . The blow startled Bane , cutting him deeply and forcing him to drop his weapon . The pain , however , was fuel for Bane ' s rage , and with it he unleashed a Force wave that knocked his oppressors clear away from him . Now the lane was clear for Bane to cut the Ithorian Jedi down . He recalled his lightsaber to his grasp and approached Worror . When Othone realized Bane ' s intentions , he used the Force and pushed Worror out of harm ' s way . This , however , marked the beginning of the end for the Jedi . Tides turn . Johun Othone ' s Force push saved Worror , but at the cost of his beneficial battle meditation . Immediately the effects were felt by Sarro Xaj , who was no longer as strong as he had previously been . As he turned his head to see what happened , Zannah used this opportunity to conjure her spell of insanity against him . Xaj was instantly driven to madness by its effects , and Zannah ducked in and cut him down without hesitation . She then cloaked her Force essence with her sorcery , sneaked up behind Raskta Lsu , and impaled her . Lsu crumpled to the floor , also dead . With only two Jedi left to face him , Darth Bane severed Othone ' s weapon - hand easily and proceeded to disarm and behead Farfalla . Bane then attacked Worror , slashing at his four throats and fatally wounding him . However , before Bane could use his purple lightning to electrocute the wounded Othone , Worror used his last bit of strength to trap himself and Bane in a Protection bubble , causing the Force lightning to electrocute him and Bane instead . Worror was dead , and Bane fell to the floor unconscious , a smoking , orbalisk - encrusted husk . Aftermath . Othone sent his opponent a pleading look , but it was ignored . Zannah ran her lightsaber blade through his chest as he lay on the floor . With Johun Othone dead , the contest was finally over . Zannah rushed to Bane ' s side and proceeded to aid her wounded Master . Noticing that the room outside had grown considerably quiet , Darovit emerged from the closet where Zannah previously instructed him to hide . When he saw Bane , he informed Zannah that dead orbalisks immediately release toxins upon death , and that Bane ' s chances for surviving their poison were small . Zannah knew of only one other individual with enough healing capacity to assist her , and he was back on Ambria . Shortly thereafter , the Sith left Tython in search of the healer Caleb on Ambria . Behind the scenes . The duel on Tython was written and conceived by Drew Karpyshyn for his 2007 novel " " . Karpyshyn chose the duel to be the end of three new Jedi characters Lsu , Xaj , and Worror , as well as the already established characters of Farfalla and Othone . Karpyshyn also used this event as the catalyst for the death of the character Darovit . The duel was mentioned in the subsequent " " .
