Mission to Prakith ( Darth Wyyrlok ) A mission to Prakith was undertaken in 137 ABY by the Sith Lord Darth Wyyrlok III , chief lieutenant of Darth Krayt ' s One Sith Order . The necessity of the mission was born out of a need by Wyyrlok ' s Master , Krayt , to rid himself of the Yuuzhan Vong implants that were threatening to end his life . After tirelessly researching ancient Sith secrets for answers , Wyyrlok consulted a Sith holocron in his possession , that of the long deceased Dark Lord Darth Andeddu , who was known to have preserved his essence for a time after his own death . Wyyrlok then traveled to the Deep Core to Andeddu ' s homeworld of Prakith , searching for information that would assist Krayt . Wyyrlok managed to find Andeddu ' s Keep , where he encountered a previously unknown Sith cult called the Malevolence — one that worshiped Andeddu , and also refused to allow Wyyrlok further entry into their domain . Wyyrlok would not be denied , however , and he killed all the cultists save one named Gerlun , who revived Andeddu ' s deceased corpse at the cost of his own life . Andeddu then engaged Wyyrlok in a duel of Force abilities , a battle that Andeddu ultimately lost . With the ancient Sith Lord dead for a second time , Wyyrlok returned Andeddu ' s body to its sarcophagus and sealed it within . Wyyrlok ' s mission was partially unsuccessful , as he was still unable to obtain any information in Andeddu ' s vast collection of Sith lore that would help him in the preservation of Krayt ' s life . He did , however , recognize what was truly killing the Dark Lord — his own doubts that he would not survive to see his dream of a stable galaxy under Sith rule fulfilled . Prelude . Decades before the end of the Sith – Imperial War and the onset of the Second Imperial Civil War , A ' Sharad Hett , who would become Darth Krayt , Dark Lord of the Sith , had been captured by the extra - galactic Yuuzhan Vong species and implanted with their Yorik - Kul slave seeds . Though able to combat the effects of the seeds through his growing strength in the dark side of the Force , Hett was slowly losing his battle with them . By 137 ABY , he had assumed the mantle of Dark Lord and restyled himself as the Dragon of the Sith , but the coral seeds still threatened to turn him into a mindless shell of a man . For years Krayt was able to sustain himself through healing trances and extended periods of stasis , and he was looked after by the most trusted of his servants , the latest of them being Darth Wyyrlok the third . Despite being the most learned of Krayt ' s Order in Sith lore and ritual , Wyyrlok was unable to find a way to cure that which afflicted his Master . Thus , he consulted a holocron in his possession , one that belonged to an ancient Sith Lord named Darth Andeddu , who was known to have reanimated his flesh after his own death . The gatekeeper of Andeddu ' s holocron refused to reveal its secrets to save Krayt , whom it considered a pretender to the Sith legacy . Only after Wyyrlok alluded to actually reviving Andeddu ' s body did the gatekeeper reveal the location of Andeddu ' s Keep , on his homeworld of Prakith . Wyyrlok immediately set out in his personal fighter to the Deep Core , in search of Andeddu ' s domain and his coveted life - sustaining abilities . The mission . Arrival on Prakith . Once arriving on Prakith with Andeddu ' s holocron , Wyyrlok entered the dilapidated fortress of Darth Andeddu , and was soon confronted by members of the Malevolence cult , guardians of Andeddu ' s tomb . Refusing to allow Wyyrlok to pass , they approached him with ignited lightsabers , intent on killing him . However , Wyyrlok displayed his proficiency with Sith sorcery , using illusions to trick the cultists into killing each other . All perished except for one , Gerlun , who swore fealty to Wyyrlok and led him to Andeddu ' s tomb . With Andeddu ' s holocron in hand , Wyyrlok was instructed by its gatekeeper to place the holocron on Andeddu ' s body to revive him , and thus learn all his secrets . Wyyrlok refused and was instead content with simply learning what he could from Andeddu ' s vast collection of books and scrolls . In an attempt to avenge himself on Wyyrlok for defeating his fellow cultists earlier , Gerlun used the Force to grab the holocron and placed it on Andeddu ' s body , and to both of their surprise , the holocron ' s power was burned out , as Gerlun ' s own life force was drained to restore Andeddu ' s life . Confrontation with Andeddu . Although Andeddu had been revived , he refused to share his knowledge with Wyyrlok , stating that he believed that true Sith did not share power . He then attacked Wyyrlok with a barrage of Sith lightning , but Wyyrlok absorbed it in the palm of his hand . Andeddu challenged Wyyrlok to a duel of Force abilities , immediately Force - pushing him away while creating illusions of massive rocks , which he then hurled at Wyyrlok . Wyyrlok was not so easily bested , and he quickly saw through Andeddu ' s tricks . He realized that Andeddu had a fear of death , and he took control of Andeddu ' s illusions of lava and flames to seemingly destroy all of Andeddu ' s books and scrolls . Mortified by the destruction of his precious artifacts , Andeddu believed Wyyrlok ' s illusion to be real even as Wyyrlok turned the lava and flames against his opponent . Andeddu perished a second time , consumed by his own fears of dying . Wyyrlok placed Andeddu ' s soulless body back into its tomb and proceeded to study much of the lore in Andeddu ' s collection . However , nothing that Wyyrlok found in Andeddu ' s Keep spoke of any way to heal or preserve life through the dark side of the Force . What Wyyrlok did realize was that more than just physical affliction was killing Darth Krayt — his doubts of living long enough to ensure stability in the galaxy were having an equal effect on him as were the Vong slave seeds . Taking several books and scrolls , Wyyrlok left the keep and returned to his Master , even more determined to find another way to heal him . Aftermath . Eventually , Krayt did uncover a way to finally rid himself of the seeds but was unable to make full use of the power . Sometime after Wyyrlok ' s mission to Prakith , Krayt was lured into a trap by the Jedi and Imperial Knight s of the Fel Empire , where he briefly subjected himself to the healing powers of the ancient Sith spirit of Karness Muur , who was using one of the Jedi as a host body . When the trap was sprung , Krayt was mortally wounded by one of the Imperials , shortly after figuring out how Muur was killing the slave seeds . When Wyyrlok found him to be alive , Krayt requested that Wyyrlok place him in a bacta tank so that his current wounds could be healed while he grew strong enough to complete the purging process that Muur had started . Instead , Wyyrlok enacted one of the core philosophies of the Sith and betrayed his Master by murdering him . Behind the scenes . The mission to Prakith first appeared in the twenty - seventh issue of the " " comic series titled " " , by writer John Ostrander . Ostrander uses this mission to expand somewhat on the backstory of Darth Andeddu by introducing both his homeworld and the Malevolence cult . Ostrander reveals here that it is not just the Yuuzhan Vong implants that threaten Darth Krayt ' s life , but that his doubts and fears play into his failing condition as well .
