Battle on Had Abbadon The Battle on Had Abbadon took place in 137 ABY , and was the result of a trap set up by a mixed band of both Jedi and Imperial Knight s to assassinate Darth Krayt , Dark Lord of the Sith and reigning Galactic Emperor . The battle commenced after Krayt ' s Imperial garrison was attacked on Had Abbadon by the group of Knights , and one of Krayt ' s servants , Darth Reave , was allowed to escape in order to inform Krayt that Jedi Cade Skywalker was among the perpetrators . Krayt was also summoned by Karness Muur — whose spirit inhabited Jedi Master Celeste Morne , Skywalker ' s other associate . Muur offered to heal Krayt of the Yuuzhan Vong implants that were killing him in exchange for a partnership in galactic rule , only if the Dark Lord came alone to Deep Core world . Krayt did not follow Muur ' s instructions , and instead arrived on Had Abbadon with Darths Maladi , Stryfe , and Talon , with his lieutenant Darth Wyyrlok remaining behind on their ship . In spite of Krayt ' s defiance , Muur still chose to demonstrate his healing power . It was at this moment that Jedi sprung their trap with the Imperials , engaging Darth Krayt and his Sith Lords in battle . Morne commanded her rakghoul mutants to attack as she dueled with Krayt . Imperial Master Azlyn Rae seized an opportunity to cut the Dark Lord down , and mortally wounded him . Morne then subjected Krayt to a lethal torrent of Force lightning , inadvertently engulfing Rae as well . The battle appeared to be over when Krayt seemingly fell to his death , and Celeste Morne was slain by Skywalker , after she asked him to free her of Muur ' s spirit . The Jedi and Imperials then collected their wounded , and fled Had Abbadon . Meanwhile , Darth Wyyrlok landed a shuttle planetside to collect his defeated Sith brethren , where he also found Darth Krayt to be alive . When the Dark Lord requested that Wyyrlok tend to his injuries , the Chagrian instead defeated and presumably killed him . However , after suffering severe injuries at the hands of Wyyrlok , Krayt was resurrected and soon revealed his existence to the mutinous Sith . Prelude . By 137 ABY , Darth Krayt felt as though his days were numbered , and that he would not live to see his dream of a stable galaxy under Sith rule come to pass . He was still unable to purge his body of the Yuuzhan Vong biots that threatened to consume him , despite relentless searching for ways to do so . Krayt had received word from one of his minions that Cade Skywalker , a Jedi with remarkable healing powers , had engaged and defeated Krayt ' s garrison on the Deep Core planet of Had Abbadon . Krayt had also received a summons from an ancient Sith Lord named Karness Muur , whose spirit inhabited a female Jedi Master named Celeste Morne . Muur appeared to have Skywalker held captive on Had Abbadon , and offered Krayt both Skywalker as a prisoner and a chance to be healed by Muur ' s own power — should Krayt allow Muur ' s spirit to inhabit his body instead . Muur told Krayt to come alone to Had Abbadon , and if he did not , Muur would kill not only Skywalker , but Krayt as well . However , Skywalker and Morne were actually attempting to lure Darth Krayt to the Deep Core , where they would ambush him and attempt to kill him . Along with the Twi ' lek Jedi Shado Vao , they partnered with Imperial Knight s Antares Draco , Ganner Krieg , and Azlyn Rae to lie in wait for the Dark Lord of the Sith . All parties hid their presences in the Force , and awaited the arrival of the enemy . Krayt touched down on Had Abbadon with Darths Maladi , Stryfe , and Talon , against the explicit orders of Muur . His primary advisor , Wyyrlok , was ordered to remain in orbit and gather more information on Muur and the claims of his power . Muur appeared before Krayt in the body of Morne , and Skywalker appeared to be bound in their custody . Muur condemned Krayt for his defiance , and reminded him of their deal ; but when Krayt questioned the spirit ' s healing abilities , Muur briefly demonstrated them . At that moment , Skywalker called his lightsaber to his hand while loosing his bonds , and attacked Darth Talon , who had sensed his intent in the last moment . Imperials Draco , Krieg , and Rae , along with Jedi Shado Vao sprung their trap , and arrived to do battle with the Sith . The battle . Through Muur ' s talents with Sith magic , Morne commanded her army of Sithspawn - rakghoul s to attack Krayt , while the other Lords dueled with the Jedi . Darth Stryfe dispatched the rakghouls surrounding Krayt with Force lightning , while Darth Maladi fought with Shado Vao . She openly regarded her opponents with respect for developing a plan with Sith undertones as she assaulted the Twi ' lek with her own lightning barrage . Despite the ferocity of her attacks , Darth Maladi remained evenly matched with Vao . After defeating Darth Talon in a brief encounter , Skywalker attacked Stryfe . He Force - pushed the Sith Lord into a pile of thermal detonators set by Skywalker ' s friend Jariah Syn . The resulting explosion engulfed Stryfe , and threw him off the platform . Skywalker then went to battle with Morne ' s rakghouls , who were running rampant and terrorizing Jedi , Sith , and Imperial Knight alike without discrimination . In the midst of fighting off the Sithspawn , the Imperial Knights had fallen back to consider their role in the current battle . Draco felt it was their duty to retrieve Morne ' s Sith talisman , which gave her the power to transform non Force - sensitive beings into rakghouls . However , Rae believed that destroying Krayt was paramount , and that the three of them should work to that end in unison . Draco responded by Force - pushing Rae to the ground in disagreement , before Krieg interfered . Draco then attempted to move in on Morne , but was immediately found out by her , and repelled with the Force . Muur ' s spirit then took control of Morne and exposed Draco ' s treacherous motives , while vowing to kill the Jedi , turn Skywalker ' s companions into rakghouls , and take Darth Krayt ' s body as its own . At the last moment , Krayt repelled all the rakghouls with an immense blast of force lightning , temporarily interrupting the battle . He then fell upon Morne , coaxing her to embrace the dark side power of Muur that Krayt felt within her . Abandoning their lightsabers , Krayt and Morne exchanged volleys of Force lightning . Maladi fell in beside the Dark Lord , and added her power to his in an attempt to overpower Morne . Seeing that Krayt was occupied , Azlyn Rae called for Skywalker to cover her while she attempted to finish Krayt . Skywalker fended off the advancing rakghouls as Rae launched herself at Krayt from behind , and succeeded in stabbing him through the chest with her lightsaber . Krayt ' s concentration suddenly broken , Muur seized the chance to unleash a massive torrent of lightning — one that fully consumed both Rae and Krayt , and scattered the remaining combatants around the platform . Muur then hurled Krayt ' s defeated body over a nearby cliff to his apparent death . Rae received severe burns over most of her body with nearly all her hair singed away . Aftermath . In the wake of the battle , the Sith were gone , and the rakghouls had been wiped out . Morne was able to momentarily wrench control of herself from Muur before confronting Skywalker . Knowing that Muur would soon take permanent control , Morne acknowledged her fate and begged Skywalker to kill her . He obliged her by running her through with his blade . Upon her death , Morne ' s body turned to dust . The amulet of Muur ' s in Morne ' s possession that both housed his spirit and power , now free from Morne ' s body , immediately latched onto Skywalker ' s arm . Muur believed that he would make this Jedi his new thrall ; instead , Cade displayed his strength of will by resisting Muur ' s temptation . He poured the Force into the weak points of the talisman and caused it to shatter , which in turn caused Muur ' s spirit to fade . Cade then turned his attention to Azlyn ' s condition and moved to take her aboard the " Mynock " to get help . He was stopped by Ganner who claimed that as an Imperial Knight , Rae belonged with them . However , Vao used a force push to knock Ganner and Draco away and he , Cade , and the rest of Cade ' s crew left to seek help from Bantha Rawk . Darth Wyyrlok , having sensed his master in need , had journeyed to the planet surface . There at the bottom of a canyon , he came across Krayt ' s broken and burned body . Wyyrlok was shocked to discover that Krayt was still alive , having used the Force to cushion his fall . Krayt ordered Wyyrlok to take him to a bacta tank as his encounter with Muur had taught him the knowledge he needed to finally heal himself of the coral growths on his body . However , Krayt would never get a chance to use this knowledge . Claiming that sometimes for a cause to continue , the leader of that cause must die , Wyyrlok killed Krayt with Force lightning before taking his body to be buried on Korriban . However , Krayt was able to resurrect himself through the use of implants , and on Korriban , he once more revealed himself to the mutinous Sith . The next year , Krayt led an attack on the Temple of the Sith on Coruscant and killed Wyyrlok in retaliation for his betrayal .
