Grand Festival of Empress Vaylin The Grand Festival of Empress Vaylin was a lavish party thrown by Vaylin , Empress of the Eternal Empire of Zakuul , to celebrate her glory after the recent victories over the Alliance that opposed her . Meanwhile , the Alliance launched Operation Dragon ' s Maw , using the party to get close enough to Vaylin for a strike . Magistrate of Revelry Indo Zal who organized the party secretly hated Vaylin for years and contacted the Alliance with a plan on how to bring her down , offering to provide disguises and security clearances for Theron Shan and the Alliance Commander in exchange for them saving captured Zakuulan rebels from public execution during the party . The Commander held a key to Vaylin ' s mental conditioning , but required a diversion to get close enough to trigger it , which the rebels were meant to provide . The Commander and Theron Shan traveled to the Palace of the Eternal Dragon disguised as two Knights of Zakuul , while Lana Beniko provided remote support from a nearby shuttle . After meeting with Indo Zal , Theron and the Commander installed Ion charges throughout the Palace to disable the rebels ' shock collars . when Vaylin began her speech , the Commander triggered the ion charges which freed the rebels and activated Vaylin ' s conditioning , making her powerless to retaliate . However , their confrontation was interrupted by arrival of Vaylin ' s brother and former Emperor Arcann , who arrived with a group of loyalists and attacked the Palace . After saving the rebels from execution by fighting beasts , Theron and the Commander pursued Vaylin and interrupted the duel between siblings , inadvertently allowing Vaylin to escape . Arcann then offered to join the Alliance to atone for his past crimes , and the Commander agreed to take him in , but Vaylin ordered the Eternal Fleet to bombard the entire Palace to rubble , with her supporters still inside . Lana picked the Commander , Theron and Arcann in a shuttle just before the entire Palace collapsed , killing multiple civilians and tarnishing Vaylin ' s public image among the people of Zakuul . Prelude . After regaining full control of the GEMINI captains that commanded the Eternal Fleet , Eternal Empress Vaylin send it to attack Alliance outposts and patrols . To celebrate her victory , Vaylin ordered her Magistrate of Revelry Indo Zal to organize a Grand Gestival at the Palace of the Eternal Dragon in her honor . During the party , Vaylin planned to execute a host of captured Zakuul an rebels by feeding them to wild beasts . However , Indo long desired to have revenge on Vaylin for the murder of his sister Kalya and contacted the Alliance base on Odessen , offering to provide them with a way to strike at Vaylin at the party . After Theron Shan and T7 - O1 vouched for him , Indo volunteered to prepare disguises and security clearances that would allow the Alliance Commander to get inside the Palace and trigger mental condition imposed upon Vaylin by her father . The plan required a distraction , and Indo offered to free and start a revolt among the captured rebels , causing enough chaos for the Commander to get close to Vaylin . The mission was code - named " Operation Dragon ' s Maw " and Theron Shan volunteered to accompany the Commander , while Lana Beniko and T7 - O1 provided remote support by slicing into the security grid from a shuttle that served as their getaway vehicle . The celebration . The party was impressive , with Zakuulan socialite gathering in the Palace of Eternal Dragon and toasting in Vaylin ' s name . However , leaving during the party was strictly forbidden and speaking during the royal address was punishable by death . To add to their humiliation , captured prisoners were forced to serve drinks to the guests while awaiting their execution . The fighting beasts themselves were either restrained in place on the main floor , or kept in the beast pens in the lower level , where beast master Oleg oversaw the menagerie . Music by Raz and the Ubo - Kings , a band that exploded in popularity on Zakuul , was played to entertain the guests , although the band themselves could not make it to Zakuul . Several dishes were served during the event , with six hundred bottles of Zakuulan wine ordered alone , although chef Areta Foss found the glazed kell cooked by her droid assistant not up to standards , ordering to throw out all thirteen prepared batches . Complimentary holograms of Empress Vaylin were provided to the guests at the reception area , while the HoloNet drones broadcasted the party for all the galaxy to see . Security was provided by Knights of Zakuul and Vaylin ' s personal Horizon Guard stationed throughout the Palace . Arriving on Zakuul wearing the the guises of two Knights of Zakuul , Theron and the Commander got inside the Palace and met with Indo Zal . He provided them with Ion charges to be attached to security relays throughout the Palace , so that they could be detonated at once and disable the rebels ' shock collars . Leaving the task to the Alliance , Indo returned to Vaylin ' s side , however he was caught spying on her during a holocall with Jarak , which blew his cover and earned him a collar of his own . Theron and the Commander worked their way around Palace security dressed as Zakuul Knights , using clever deception to gain access to unauthorized areas . Among other things , the Commander stole a Knight - Captain ' s shield , which allowed them to threated the other Knights with their rank , stole a foreman access card from one of the dock workers , lifted the lockdown from the security room to access the data in the server room and fed medicine to a sick exoboar Bergola in the beast pens , earning the creature ' s gratitude . After Theron and the Commander planted all six charges , Lana informed them that Vaylin was beginning her speech ahead of of schedule . Dropping their disguises , Theron and the Commander strolled into the main hall , where Vaylin was making the public address to the holocamera s . Having uncovered Indo ' s deception , she made a speech about Zakuul ' s glory and her enemies ' torment , when the Commander publicly mocked her in front of the cameras , causing Vaylin to drop Indo and the other prisoners inside the beast den . Vaylin used the Force to levitate heavy mental ornaments , intending to smash the intruders with them , but the Commander spoke the code phrase " Kneel before the Dragon of Zakuul " that triggered her mental conditioning , causing Vaylin to lose control of her powers in front of everyone . The Commander then detonated the ion charges , causing cameras to fail and lights to flicker throughout the Palace as the ion blast disabled all electronics . The remaining rebels began attacking skytrooper s and arming themselves with their weapons , while a couple of giant exoboars held on the main floor were suddenly no longer restrained and began causing havoc among civilians and the Knights of Zakuul . The attack . Vaylin ignited her lightsaber and prepared to engage the intruders in combat , when the Palace was hit by a couple of missiles . Unbeknownst to anyone , Vaylin ' s brother and former Emperor Arcann had also picked the party as the opportunity to confront his sister and arrived with a shuttle full of his loyalists , who began seeking Vaylin throughout the Palace . Seeing her brother on the holocameras , Vaylin retreated from the main hall , all exits from which were then sealed . The only way for Theron and the Commander was to follow the rebels down into the beast den , where they saved Indo and the others from a Rancor named Junior , with an unexpected assistance from Bergola and her pack . The Commander then ordered Indo to retreat with the Rebels to safety , after which they and Theron went to pursue Vaylin , who went to a remote balcony , smashing all holocams in her way . Informed by Lana about Vaylin ' s whereabouts , Theron and the Commander made their way out of the pit and into the reception area , where a fight between Arcann ' s loyalists and Vaylin ' s Knights had broken out , with beastmaster Oleg bringing his two vorn tiger s Cho ' Kri and Cho ' Ale into mix . Arcann approached Vaylin at the balcony and tried to talk his sister down peacefully , but Vaylin became convinced that her brother was complicit in her conditioning and attacked him in a fit of rage . The two engaged in a lightsaber duel , which was interrupted by the arrival of the Commander and Theron Shan . Seeing a chance to leave Arcann alone with their father ' s vessel , Vaylin threw a speeder bike at him , which she then used to leave the scene . To Commander ' s surprise , Arcann was indeed healed on Voss and addressed them peacefully , acknowledging his past crimes without signs of hostility . After Theron Shan doubted his trustworthiness , Arcann joined him and the Commander in the fight against the Horizon Guard who arrived to kill them . After the Guards were dealt with , Arcann wondered whether the Commander was controlled by his father like a puppet or merely housed his essence . Valkorion ' s spirit then revealed himself to Arcann and called him weak , to which Arcann replied that he was no longer his father ' s son and that the Commander was more deserving of the Eternal Throne than he was . Arcann then offered to join the Alliance to atone for the blood shed under his reign , and the Commander agreed to take him in , using the party holocamers to broadcast Arcann ' s new loyalty to the galaxy . Witnessing the broadcast from an Eternal Fleet warship she retreated to , Vaylin became enraged at her brother ' s betrayal and ordered the Eternal Fleet to bombard the entire Palace into rubble , regardless of her supporters still inside . Eternal Fleet ships began laying fire on the Palace , and Arcann , Theron and the Commander rushed to the landing pad where Lana and T7 - O1 were waiting for them in the shuttle . Some others managed to escape the Palace in time , but just after Lana ' s shuttle took off with the Alliance and their new friend safely onboard , the Palace collapsed from the sustained fire , crushing everyone who still remained inside . Aftermath . What was intended to be a celebration of Vaylin ' s glory turned to disastrous consequences for the Empress . Her weakness to a mental conditioning became exposed to everyone , and the act of turning on her loyal supporters resulted in her being hated by half of Zakuul ' s population . Determined to rid of her mental bonds at any cost , Vaylin took her flagship to Nathema , where Jarak promised to have a breakthrough to help Vaylin break her chains . The Alliance meanwhile did not achieve their original goal of taking down Vaylin , but found a new ally in Arcann and secured the support of Zakuulan rebels , who were largely led away from the Palace by Indo . Arcann was brought to the Alliance base on Odessen , where he was initially treated as enemy by the Alliance personnel , but the Commander insisted that having the former Emperor on their side was good for both the morale and for putting additional pressure on Vaylin . Behind the scenes . During Chapter VI : The Dragon ' s Maw player has to perform a certain set of actions to unlock access to the security relays , two of which are optional . One is to lift the lockdown from the server room and obtain the security data from it , which allows Lana Beniko to unlock a shortcurt after the fight with the Rancor , allowing the player to skip several fights along their way . The other is to use glazed kell to feed medicine to Bergola , which secures her loyalty and results in her and her pack of Brick , Lil ' Jwizzix and Rompy joining the player ' s side as combat support pets for the second half of the Chapter . If this is not done , all four exoboar s will be hostile instead , requiring the player to kill them before engaging the Rancor . After Junior is killed , player can either urge Indo Zal to lead the rebels to safety for Light Side points , or order them to attack the Knights of Zakuul for Dark Side points , which results in rebels taking heavy casualties and losing their fate in the Alliance . If during Chapter I : Wrath and Ruin player made a Dark Side choice to kill Senya Tirall , Arcann will not be healed and will arrive seeking vengeance instead of atonement . He will attack the player only be struck down , and Valkorion ' s spirit will appear to talk to his son one last time before Arcann dies , his life essence secretly absorbed by Valkorion . Afterwards , players can declare themselves Zakuul ' s protector for Light Side point or gloat at Arcann ' s downfall for Dark Side points . In the version of events where Arcann survives , players can welcome him into Alliance as an ally for Light Side points or made him openly kneel and swear loyalty for Dark Side points .
