Karae Nalvas Karae Nalvas , also known as Boss Nalvas and sometimes known by the pseudonym Fesvk Wefos , was a male Human who was a former Jedi Knight who fell to the dark side and became a rogue Jedi during the waning years of the Galactic Republic . He traveled to the planet Genarius where he became a Dark Jedi and creating a floating fortress , the " Conkesta " , to threaten the cities on the planet and unleash a war . Biography . Karae Nalvas began his career as a Padawan studying the light side of the Force under an unidentified Jedi Master in the planet Coruscant . At that time , Nalvas was considered a knowledge - seeking sentient , a skilled diplomat , and a promising scholar . In 46 BBY , Nalvas and his master were sent to an undisclosed place in the Outer Rim Territories to research a disturbance in the Force that had been detected by the Jedi Order . Although the detected ripples had been weak , their source was a planet powerful in the dark side of the Force . When the two Jedi reached the planet , both were tempted by the power of the dark side , with Nalvas embracing it . No longer a Jedi , Nalvas fought , injured and abandoned his master . The master , considering himself also tainted by the evil , contacted the Jedi Council to tell them of the danger he and Nalvas could become , and suggested sectoral quarantine to contain the evil . Nalvas disappeared for twelve years . During that time all the records of the Jedi Order about Nalvas , including those with his image , were deleted , and nobody alive seemed to remember Nalvas ' s face . However , his name and history up to this point were relatively well - known among scholars of Jedi lore . Nalvas became a dark side practitioner in the move through the Outer Rim . Although the Jedi Order received reports about this person , they did not relate them to the missing Nalvas . In 34 BBY , Nalvas recruited a Jedi Padawan , Saren Valek , and turned him into his apprentice in the dark side . Valek ' s master , the Jedi Knight Alec , began tracking Nalvas to bring him to justice . For three years , Nalvas trained Valek in the dark side , with Alec being unable to stop him . Nalvas wanted to create a mobile fortress with enough firepower to level any of the cloud cities of Genarius , a gas giant in the Cularin system . He had spent the previous years amassing resources , including money , technological blueprints and several high - and low - level employees , most of whom did not know about Nalvas ' s destructive goals thanks to some cleaver use of Nalvas ' s Force abilities . What he wanted to achieve by ravaging the Genariusan metropolises is unclear , but Alec has theorized that , if Nalvas should have taken over the main centers of business in the Cularin system , then the chain reaction could end in an open war either in - system or in a wider scale . Nalvas managed to start building the " Conkesta , " a mobile city itself with powerful shielding and almost ready for its intended goal . To do so , he used the services of several scientists , including Dr . Shilaea Motacc , an expert in large - scale propulsion systems and planetary propulsion . As Dr . Motacc would have not work for him knowing his intentions , Nalvas pretended to be entrepreneur Fesvk Wefos ( pronounced fes - vik ) from the Usable Resource Location , Recovery , and Development Corporation ( U . R . L . R . D . ) , which wanted to expand its operations to Genarius , and hired Motacc to develop a new system to propel flying cities . Secretly , Nalvas used Motacc ' s work in the " Conkesta . " In 31 BBY , the " Conkesta " was near completion . To avoid detection , Nalvas hid a skeleton - staffed " Conkesta " at a very low orbit , near the core of Genarius . Nalvas felt safer doing so , and in fact he did avoid detection . Before Motacc had finished his work for Nalvas , she was abducted during a vacation in the resort city of Rorkee , Genarius . The kidnappers were some partners of Nalvas ' s in the " Conkesta " project , who wanted the designs of the fortress for their own ends and were ready to use the force to get them . Pretending to be a worried and sympathetic employer , Nalvas ( as Wefos ) met with an independent team in Bath Rabbud ' s , a bistro in the nearby planet Cularin . In a relaxed meeting , " Wefos " convinced his new friends to investigate Motacc ' s disappearance in Rorkee for a price , and at the same time enjoy a paid holiday . He also said he was forced to hire external agents because U . R . L . R . D . did not have these kind of agents on payroll . The team rescued Motacc and took her to Nalvas . Nalvas paid them their money with a bonus and partied with them and Motacc in Bath Rabbud ' s . Even then , Motacc was unaware of the reasons behind her kidnapping or the identity of her captors . Due to this , Wefos developed a reputation of being a good payer and sending his employees to exotic places . However , when Motacc returned to her work , she discovered that her colleagues were the guilty part and , scared , she tried to escape . Fortunately , she was contacted by Alec , who had finally found Nalvas and was looking for a way to stop him . Alec helped Motacc and both of them disappeared . Alec also stole the valuable blueprints of the " Conkesta " , much to Nalvas ' s chagrin . Nalvas discovered that Alec had been seen in the so - called City of Masks , Depatar , a place in Genarius known for its strict bureaucracy and for its forced carnival for outsiders : A person without the proper permit or without a mask could be easily expelled from the city . Nalvas also discovered Alec ' s secret hideout for the stolen blueprints , but Nalvas needed to distract Alec before getting the designs . Trying to repeat his previous success , Nalvas decided to hire an independent team ( which might or might not include the same people who had rescued Motacc ) using deception and his Wefos persona . Nalvas hired professional Depataran bureaucrat Fot Ducela to help his team with Depataran permits , bought the permits that the team would surely need , booked a private dining room in Bath Rabbud ' s and met with his new agents . Nalvas falsely told his employees that Alec was a courier working for U . R . L . R . D . and that he had mysteriously disappeared with the prototype of a new resource extraction equipment before giving it to company executives . Asking them to recover both the plans and the courier , Nalvas provided the team with some available information and disguises , and sent them to Depatar . Nalvas knew that the team would probably find Alec , and that Alec would tell them about Nalvas ' s real identity and plans ; however , Nalvas used his chance to recover the lost document . Alec offered to go with the team and met with " Wefos " . Alec and the team waited for Nalvas in Bath Rabbud ' s , but Nalvas had anticipated this move . Nalvas arranged an astromech droid to show a hologram of himself mocking and showing the blueprints , and then the droid would begin the countdown of a bomb . Although the bomb was outwardly similar to a thermal detonator , it only had the power of a fragmentation grenade . However , the end of the countdown would melt the explosive , while any unsuccessful attempt to disarm it would trigger the explosion : Nalvas liked the irony of his enemies causing their own deaths . However , at least Alec survived , and maybe the others too . Nalvas had staffed the " Conkesta " with some 6 , 000 sentients brought from other systems . Those included the Gungan Gus - Gus Tren , who called his employer " Boss " Nalvas ; it is unclear whether Nalvas was a honorific Gungan Boss or Tren was using the word metaphorically . Two weeks after Nalvas ' s recovery of the plans , the " Conkesta " was almost ready to attack other cities , but she was also found by Alec . Motacc and Alec ' s slicer contacts developed a virus that could affect the propulsion system of the city , theoretically sending the " Conkesta " to outer space , where it would be destroyed . Unbeknownst to them , the virus really would send the fortress down , to the planet ' s core . Alec asked the heroes of Cularin to infiltrate the " Conkesta " and upload the virus in the " Conkesta " main computer while he was busy elsewhere stopping Nalvas himself . He did not reveal whether Nalvas was in the station itself or not . Although Alec ' s raiders succeeded in hacking the " Conkesta " and doomed her to its end , they were blocked during their escape by Valek and several guards . Nalvas , appearing as a hologram , ordered all of them to kill the intruders , but some of the guards tried to leave the sinking ship . Valek died during this fight and Alec ' s allies escaped . However , Alec himself was unable to stop Nalvas from leaving the Cularin system asteroid belt and later the Cularin system . The Jedi decided to continue his mission and try to take Nalvas to justice . During the following years , Nalvas ' s name rose to prominence in the Cularin system , along with stories about his evil scheme . Jedi scholars studied the reports and rumors about Nalvas . Scholar Dazen Mok , a former Jedi himself , analyzed Nalvas ' s actions and hypothesized that Genarius held a powerful dark side energy that created the storms and that allowed fellow dark - sider Nalvas to create his fortress near the core ; however , this theory was not proved . Later , in around 20 BBY , Nalvas became the partner - in - crime of Chevin slaver Phylus Mon . Phylus Mon had been informed of the process to create Sith battlelord s , who controlled their armies using the dark side of the Force as a leash . Nalvas wanted to become a Sith battlelord . Secretly , Nalvas schemed to betray Phylus Mon after that . Following Phylus Mon ' s plan , Nalvas and other prospective Battlelords traveled to the Almas Sith fortress , where the ritual would be performed . They invaded the fortress , killing four Jedi and kidnapping two others for the ritual . During the ritual , a pendant with an orange gemstone was placed in Nalvas ' s neck . However , probably due to the interference of the Darkstaff , a damaged Sith artifact , the ritual failed : Instead of transforming them in Battlelords , Phylus Mon simply uprooted the Force essences of the candidates , which would be then stored in a crystal . Nalvas ' s and the others ' bodies were still alive , but unable to move , as their minds and souls were not there . Phylus Mon left the fortress with the crystal , but without the empty bodies . The Darkstaff would then drain the Force essences from Phylus Mon ' s secret headquarters . The bodies were found by a Jedi search team and taken to the Almas Academy . There , librarian Oden Malksch , who recognized Nalvas , attempted to analyze the amulet . When trying to take them , it cracked and suddenly Malksch ' s Force essence was forced in Nalvas ' s body . Malksch could feel that Nalvas ' s essence was trapped and that the body needed to reach it . The body felt where the essence was , so Malksch could guide a rescue team there . It is unclear whether Nalvas ' s body survived the rescue mission or not .
