Mission to Nathema Shortly after the Grand Festival of Empress Vaylin , the Alliance Commander departed with Theron Shan and Lana Beniko on a mission to stop the Eternal Empire rules from breaking her mental conditioning on a forsaken world of Nathema . Theron piloted the shuttle to Nathema system and dropped Lana and the Commander near the Sanitarium , the only structure still signs of life on the planet devastated in the Ritual of Nathema . The Commander and Lana dispatched the Horizon Guard s that guarded the entrance and ventured inside , where they learned details about Vaylin ' s conditioning from the holorecordings left by Anomid scientist Jarak . However , they arrived too late to stop Vaylin , who was subjected by Jarak to the ritual that went out of control , with Vaylin ' s power vaporizing those in her vicinity . Jarak fled to save his life and came upon Lana and the Commander , offering to lead them to a place where they could take shelter from the energy blasts . Working together , they reached the Immortal Emperor ' s vault , where Valkorion stored artifacts even he deemed to dangerous , and barely managed to get inside in time . With the power circuits fried , Beniko and the Commander went to activate the backup power generator , while Jarak was killed by a vault guardian . Inside the vault , the Commander and Lana made an important discovery of Dramath ' s holocron housing the essence of Valkorion ' s father Dramath , who told them that the holocron held the power to destroy Vitiate once and for all . Taking the holocron with them and unlocking the door , the two learned from Theron that Vaylin has already left the planet ' s surface and that the Sanitarium now threatened to collapse . The Commander and Lana rushed outside where Theron picked them up , but before they could rest , they learned from Bey ' wan Aygo that Vaylin launched an assault on Odessen . Prelude . Having become aware of the mental conditioning imposed on her by Valkorion , Eternal Empress Vaylin ordered Jarak , the Anomid scientist responsible for it , to find a way to undo the work done by him in the Sanitarium on Nathema . During the Grand Festival of Empress Vaylin , Jarak informed the Empress that he made a breakthrough and Vaylin , who suffered a humiliation when the Alliance Commander used her conditioning against her , departed Zakuul and traveled to Nathema on her personal flagship . Meanwhile , the Alliance Commander , who hosted Valkorion ' s spirit inside their head , experienced a portion of Valkorion ' s memory in which Vaylin first came back to Zakuul after spending years on Nathema . When the Commander mentioned it to former Emperor Arcann , Vaylin ' s brother who recently joined the Alliance , he identified Nathema as the site of Vaylin ' s conditioning and deduced that she was only coming back there because she found a way to break it . Nathema was a Void in the Force ever since Vitiate killed all life on it with his ritual , too dangerous for recently redeemed Arcann to visit , so the Alliance Commander departed there with only Lana Beniko and Theron Shan , two of their closest advisors . The mission . Theron piloted a shuttle to Nathema system , where Lana began feeling the effects of the Force void before even setting foot on the planet . Even Valkorion found his power diminished in this place , though he promised to shield the Alliance Commander and their companion from its worst effects . The shuttle ' s sensors identified the Sanitarium as the only structure on the planet showing signs of life and Theron dropped off Lana and the Commander not far from it , taking the shuttle to a safe distance afterwards . Meanwhile , Vaylin landed at the entrance to the Sanitarium with a host of the Horizon Guard s , where she was greeted by an Abyssin Keeper , who informed Vaylin that Jarak was waiting for her inside his laboratory . The Empress ordered the Horizon Guards to wait outside and ventured in , reaching the habitat in which Jarak kept his twisted experiments . Jarak arrived to witness Vaylin slaughter a trio of his mutated Acklays and informed Vaylin that everything was prepared for her in the main lab , while Lana and the Commander made their way to the entrance of Sanitarium , where they dispatched the Horizon Guards and followed Vaylin inside . Within the walls of the Sanitarium , Lana and the Commander proceeded to cut down skytrooper s , Nathema Zealot s and Keepers that stood in their way , while learning about Jarak ' s role in Vaylin ' s conditioning there from his holorecordings . In the main laboratory , Jarak had prepared a large circular arena surrounded by massive energy orb nodes and explained to Vaylin that the process to break her conditioning would be even more extreme than before , with nobody else surviving it so far . However , Jarak also assured the Empress that her unparalleled strength in the Force would give her a chance that nobody else had and Vaylin agreed to proceed . The pillar orbs pierced Vaylin ' s body with energy beams , dealing her enormous pain , and causing her power to lash out of control . As Vaylin struggled , the Force blasts emitted from her body evaporated several Keepers and Zealots , while Jarak had fled the room to save his life . He ran into Lana and the Commander and quickly explained that only he knew a location of a safe place , asking them to escort him there through the beasts that went mad from Vaylin ' s power . To assure their mutual survival , Jarak led them to the Emperor ' s Vault in the Sanitarium ' s lower levels , where they barely managed to get inside to avoid the energy blasts that ravaged everything outside and fried the vault ' s power circuits . All this time , Vaylin was alone at the mercy of Jarak ' s inventions and continued to suffer unbearable pain . Finally , determined not to die in the place she hated so much , Vaylin gathered all of her remaining strength and overpowered Jarak ' s machines , causing them to explode one by one and freeing her from their grasp . As soon as the pain stopped , Vaylin could feel her bonds has been broken and departed the surface of Nathema . Inside the vault , the spirit of Valkorion informed the Commander that Vaylin had broken free from her bonds before fading due to Void in the Force that permeated the place . Jarak told the Commander and Lana about the vault ' s backup power generator , warning them to beware the Vault ' s ancient guardians . After they restored the power , the Commander and Lana made an important discovery by finding Dramath ' s holocron , which still housed the essence of Valkorion ' s father killed over 1300 years ago . Dramath told the two the history of his torment and revealed that the holocron held the power to destroy Vitiate once and for all . The Commander ordered Lana to take care of the holocron , since the moment they stepped outside the vault Valkorion would become aware of Commander ' s actions once again . Jarak was killed by a Vault Guardian and the Commader and Lana had to fight off three large Voreclaw s , before finally getting the door of the vault open . Theron informed them that Vaylin has already left the surface and the two rushed to escaped the Sanitarium which now threatened to collapse . The Commander and Lana made their way to the landing platform outside where Theron picked them up , leaving Nathema behind . Aftermath . The Alliance ' s original goal ended in failure , with Vaylin succeeding in breaking her chains without even realizing that the Alliance attempted to stop her . Upon the return to her flagship , Vaylin demonstrated her full power by Force Crush ing everyone on the bridge and using it to remotely trigger the Sanitarium ' s destruction , before ordering her ships to leave Nathema ' s orbit . She then immediately ordered the Eternal Fleet to launch an assault on Odessen , intending to finish the Alliance for good . The Alliance , however , managed to locate and obtain Dramath ' s holocron , a relic that would prove crucial to Vitiate ' s ultimate destruction , and after learning from Bey ' wan Aygo about the attack on Odessen , Theron immediately took the shuttle back to their base . Having sensed her daughter break her mental bonds , Senya Tirall awoke from her long coma on Odessen and joined the ranks of its defenders alongside Arcann . Behind the scenes . During Chapter VII : Into The Void player has to choose between freeing Lord Dramath from his holocron prison and allowing him to pass on for Light Side points , or keeping him bound for Dark Side points . The latter option will allow Dramath to join as a temporary companion during Chapter IX : The Eternal Throne , making the fight against Vaylin ' s spirit much easier .
