Confrontation on Ambria A confrontation took place on the planet Ambria in 990 BBY that culminated in a short lightsaber duel between the failed Jedi Padawan Darovit and a team of fourteen Jedi . Darovit had discovered his cousin , the Sith apprentice Darth Zannah , on the planet Coruscant , where she was undercover as a Jedi . Fearing she would be discovered , Zannah took Darovit to her Master , Dark Lord of the Sith Darth Bane , on the planet Tython . They were followed by a group of Jedi who engaged Zannah and Bane in a duel , and although the Jedi were killed , Bane suffered life - threatening injuries . After the duel , Zannah took Bane to the healer Caleb on Ambria , who refused to heal the dying Dark Lord unless Zannah surrendered her Master to the Jedi Order . Zannah accepted Caleb ' s demands and sent word to the Jedi that a Sith Lord still lived . Zannah , however , betrayed and murdered Caleb after his part of the bargain was upheld . She then used Sith magic to drive Darovit insane and furnished him with a gold - bladed lightsaber . When a team of six Jedi Masters and eight Jedi Knights led by Master Tho ' natu arrived on Ambria to arrest the Sith Lord , they were attacked by the insane Darovit . Believing him to be the Dark Lord , the Jedi quickly cut him down . Assuming the Sith had finally been eliminated from the galaxy , the Jedi left the planet , allowing Bane ' s Order of the Sith Lords to survive . The Sith remained hidden from the Jedi for nearly a millennium , until they finally revealed themselves with the power to take over the galaxy . Prelude . Darovit — a failed Jedi Padawan and redeemed Sith — traveled to the Jedi Temple on the galactic capital planet Coruscant in 990 BBY , where he planned to reveal that he knew of two Sith Lords who had survived the New Sith Wars . Before he was able to speak out , however , he found his cousin , Sith apprentice Darth Zannah , who was in disguise as Nalia Adollu , a Padawan who had been stationed on the planet Polus since 995 BBY . Fearing that she would be exposed , Zannah fled , taking Darovit with her to meet her Master , Dark Lord of the Sith Darth Bane , on the planet Tython . Nevertheless , a group of five Jedi led by Jedi Lord Valenthyne Farfalla tracked down the Sith and engaged Zannah and Bane in a duel . Although the Jedi were slaughtered , several of the parasitic , impenetrable orbalisk s that formed Bane ' s armor were killed by his own expulsion of Force lightning . The orbalisks released deadly toxins into his body for which there was no known antidote . Zannah took Bane and Darovit aboard the starship " Loranda " and flew to the planet Ambria to find the healer Caleb , who had saved Bane ' s life ten years earlier , during the New Sith Wars . However , Caleb had only healed Bane because the Sith Lord had threatened to harm his daughter . Fearing that Bane would return and threaten her again , the healer had sent his daughter away , forcing her to move to another planet and change her name so that she could never be tracked down ; Caleb himself did not know her location . The healer further resisted Zannah ' s attempts to torture him into compliance , and Darovit suggested that Caleb might heal Bane if Zannah called in the Jedi to arrest her Master . Caleb agreed to the idea , but Zannah was hesitant , as there was still much for her to learn from her Master . If she turned him over to the Jedi , she knew that many secrets of the Sith he had not yet revealed to her would likely be lost forever . On the other hand , if she did not send the message , Bane would die and the secrets definitely would be lost . Darovit pressured her to save Bane ' s life , join the Jedi when they came , and turn away from the dark side of the Force . Finally , realizing that she had no choice , Zannah accepted the plan . She sent a message drone to the Jedi , and Caleb healed Bane , who eventually regained consciousness . When Zannah told her still - weakened Master what she had done , he expressed his anger and told her to kill him rather than allow him to fall into the hands of the Jedi . Zannah , however , had formulated a plan — she murdered Caleb , mutilated the healer ' s corpse , and used her skills in Sith magic to drive Darovit insane . She then gave Darovit Farfalla ' s gold - bladed lightsaber with the intention of having Darovit attack the Jedi when they arrived . The confrontation . Zannah hid herself and her Master in a small trapdoor inside Caleb ' s hut and hid their presences in the Force so that the Jedi would not sense them . Meanwhile , a team of six Jedi Masters and eight Jedi Knights led by the Jedi Master Tho ' natu arrived on Ambria in the Jedi cruiser " Light of Truth " to take the Sith into custody . The Jedi quickly found the dismembered corpse of Caleb outside of the healer ' s shack . Moving toward the hut , Tho ' natu called out to the Sith that they had arrived and were there to help . Darovit then emerged , screaming and brandishing the golden lightsaber of the recently fallen Farfalla . He attacked Tho ' natu and the other Jedi , who fell upon him and killed him in seconds . Aftermath . Recalling that Farfalla had used a golden lightsaber , Tho ' natu assumed that Darovit was the Sith Lord who had killed the Jedi on Tython . Noticing that Darovit was missing one hand , he also surmised that Darovit had been grievously injured and had come to Caleb for help . Tho ' natu further inferred that the healer had sent the message to the Jedi shortly after Darovit ' s arrival , but Darovit had found out and , once healed , had killed Caleb in retaliation . The Jedi , mistakenly convinced that they had finally destroyed the last of the Sith , took Caleb ' s remains to Coruscant for a proper burial and left the " Loranda " for junkers . Zannah and Bane escaped a few days later in the starship , and Bane expressed his approval of Zannah ' s actions . The Jedi Order honored the five fallen Jedi who had been killed at Tython by engraving their names and images on a white block of stone , in which their lightsaber hilt s were also inlaid , and Caleb was honored on the list as well . Jedi Master Obba , who had been a member of Tho ' natu ' s strike team and who by 980 BBY had become a member of the Council of First Knowledge , recounted the events of the confrontation to Princess Serra of Doan , who was actually Caleb ' s daughter . Upon hearing the Jedi ' s description of the insane man they had killed , Serra became convinced that the Jedi had been fooled — she remembered Bane ' s appearance from her childhood and was certain he had survived . She thus hired an assassin , the Huntress , to hunt down Bane and capture him . Nevertheless , Bane escaped and enlisted the Huntress as his Sith apprentice ; and she proceeded to kill Serra . Zannah ' s actions allowed Darth Bane ' s Order of the Sith Lords to remain hidden from the Jedi for nearly a millennium — 990 BBY to 32 BBY — permitting them to grow in power until they were strong enough to take on the galaxy once more . In 19 BBY , the Sith succeeded in nearly eradicating the Jedi and establishing the first Galactic Empire . Behind the scenes . The confrontation was created by author Drew Karpyshyn for his 2007 novel , " " . The event served to present the deaths of two established characters , Caleb and Darovit ; Karpyshyn also used the event as the origin of the Jedi Order ' s belief that the Sith were extinct , as presented in . The confrontation later received mention in " " , the sequel to " Rule of Two " and the third and final installment in Karpyshyn ' s " Darth Bane " trilogy . In the novel , Caleb ' s daughter is told of the events of the confrontation from the Jedi ' s point of view .
