Raid on Darvannis A Mandalorian raid on the planet Darvannis took place as part of the Alliance ' s revolt against the Eternal Empire in 3631 BBY . After SCORPIO revealed that the GEMINI droids were produced from a single template called GEMINI Prime in the Darvannis factory , the Alliance leadership decided to retrieve it , although they did not have enough forces for a major assault . Theron Shan responded by calling in a favor to Shae Vizla , now holding the title of Mandalore the Avenger , and the Alliance Commander traveled to Darvannis , where Vizla ' s Mandalorian clans were itching for both payback against the Eternal Empire and a chance to re - arm themselves with the spoils from the factory . Mandalore ' s best scout Torian Cadera joined the Commander in capturing the perimeter guns and reprogramming them to target the weapons factory , while Breyer Chorn and his forces took down the factory ' s shield generator . Afterwards , Vizla informed the Commander that the fighting would resume the next day after her troops had some rest . The next morning , Torian again joined the Commander in neutralizing the enemy forces at the Zakuulan listening post , while Shae Vizla and her second - in - command Khomo Fett led the attack against the factory ' s power stations in preparation for the main assault . With the factory ' s power stations taken over by Clan Beroya and Clan Fett warriors , Shae Vizla gathered her warriors to rally them before leading them inside the factory to claim as many weapons as possible , while Torian accompanied the Commander on a mission to secure the GEMINI Prime . The Commander successfully removed the droid from her alcove , while the Mandalorians retreated from the factory . In the aftermath of the battle , Torian asked the Mandalore to join the Alliance as her representative , and after Vizla granted his request , traveled to the Alliance base on Odessen along with the Alliance Commander . Background . During the Eternal Empire conquest of the galaxy Mandalore the Vindicated fell in combat and many of the Core Worlds were blockaded by the Star Fortress es , trapping almost half of Mandalorian clans on those worlds . Most of the other clans had scattered , and Shae Vizla became the new Mandalore . In 3631 BBY Vizla was contacted by Theron Shan , a representative of the Alliance that opposed Zakuul , who offered the clans a chance to strike back against the Eternal Empire by assaulting the weapons factory on Darvannis . The factory produced starships , weapons , skytrooper droid forces and boasted fully automated defenses , including kilometer - deep tunnels , energy shield ing , defensive turrets and anti - infantry ground cannons . For the Alliance , the goal of the attack was to retrieve the GEMINI Prime , a template for the GEMINI droids which could be the key to taking over Emperor Arcann ' s Eternal Fleet . Vizla accepted the offer , seeing not only an opportunity for payback , but a way for Mandalorian clans to re - arm themselves for the first time in years . The battle . Having assembled a dozen of clans , including Fett , Chorn , Beroya , Cadera and Farr , Vizla led them to Darvannis , with Khomo Fett as her right - hand man . Having established a camp well outside the range of the factory ' s guns , the Mandalorians have laid siege to the factory , placing rotating assault teams of two hundred commandos each around it and sending scouts to determine the factory ' s defenses . Shae Vizla and Khomo Fett were soon joined by the Alliance Commander , who arrived to assist with the assault and personally retrieve the GEMINI Prime . Vilza paired the newcomer with her best scout Torian Cadera and send them to capture the perimeter defense guns and reprogram them to target the factory itself . Meanwhile , forward teams led by Valk Beroya and Breyer Chorn moved to take down the factory ' s energy shield generators . The factory ' s perimeter was patrolled by both skytrooper forces and Eternal Empire Walker s , which Torian and the Commander faced while reaching the guns in sector nine , while Valk Beroya fought her way through sector four , losing several warriors along the way . After losing Hashar and a dozen other more warriors , Clan Chorn forces reached the shield generators and rigged them with explosives . However , the remaining warriors were outflanked by skytroopers and unable to withdraw , holding their ground as the detonations took down the factory ' s shields . Breyer Chorn then contacted Torian Cadera , giving him a green light to fire the factory ' s guns at their position , preferring to die in an artillery strike rather than to fall to a bunch of machines . Torian agreed , but the Alliance Commander intervened and ordered Torian to retarget the guns , giving Chorn and his forces a route to withdraw instead . In the end , that wave of assault cost the lives of twenty - eight warriors , but the factory ' s shields went down and the inner ring of defenses had suffered severe damage . The day coming to close , Mandalorians held a Kote ky ' ram Death Ceremony for their fallen comrades , while celebrating their own survival during the night . The next morning , Vizla send Clans Beroya and Fett to take the factory ' s north and south power stations respectively , to weaken the skytroopers for the final push . When Torian noted that this put air and sniper units at the Zakuulan tactical post in a position to outmaneuver the clans , the Commander volunteered to keep the droids distracted long enough for the Mandalorians to reach the power station , with Torian again joining their side . Vizla and Fett themselves led this assault , in which Valk Beroya ' s team lost Yenko Farr and his three sisters . Torian and the Alliance Commander successfully contained the droids , and after both power stations were down , Vizla asked them to shut down factory ' s perimeter sensors in order to cover their retreat . Torian watched over reinforcements while the Commander shut down the sensors , after which Lana Beniko made an unexpected call , providing the Commander with detailed schematics of the factory obtained by Theron Shan , to better plan the assault . Ready to move inside the factory , Vizla shared her battle plan with the Alliance Commander , who added to it by providing the factory schematics . Vizla gave a rallying cry to her warriors and went to lead the assault herself , leaving it to the Commander and Torian Cadera to retrieve the GEMINI Prime . Inside the factory , Khomo Fett led the warriors to the armory , while Jos Beroya ' s men ambushed the security office and Dalash Ard demolished the skytrooper assault force with ion bomb s . The schematics led Khomo and his warriors straight to the armory , where they picked up two dozen plasma cannon s and went to assist the Mandalore , while Valk Beroya went for the factory ' s main reactor , even though she was down to three warriors by this point . Meanwhile , Torian and the Commander encountered and defeated skytrooper ZT - 001D , after which a few hundred skytroopers were deployed to their location to protect the GEMINI Prime . Torian volunteered to hold them off , while the Commander located the Prime and removed the droid from her alcove , shutting her down . The template unit was secure and the Mandalorians were able to secure a sufficient amount of weapons and deal enough damage to the factory before Vizla ordered an organized retreat . Aftermath . By the end of the the day , the factory was intact , but mostly offline , while the Mandalorians claimed enough plunder to re - arm themselves . In the aftermath of their victory , Khomo Fett and the other warriors felt a renewed vigor for battle , which troubled the Mandalore , who was afraid that the search for glory would lead clans against another opponent sooner than they were ready . The Commander convinced her to find a suitable outlet for their bloodlust , and Vizla agreed to Torian ' s request to join the Alliance as her representative . The Commander and Torian returned to Odessen , where SCORPIO analyzed the GEMINI Prime and explained that by plugging the Prime into the captain ' s console on any warship in the Eternal Fleet , she would be able to take control of the entire GEMINI network , and with it the Eternal Fleet itself . Identifying a lone warship scheduled to recharge its hyperdrive as their target , the Alliance leadership moved to intercept it . Shae Vizla herself later traveled to the Alliance base on Odessen , formally adding her strength and that of her warriors to the Alliance ' s cause . The Mandalorians , led by Torian Cadera , would go on to fight in the liberation of Voss and defend the Alliance base during Vaylin ' s Assault on Odessen . Behind the scenes . During " " Chapter XIV : Mandalore the Avenger player is faced with three major choices . There first is to whether to allow Torian Cadera to fire an artillery strike on Breyer Chorn and his forces , with the Light Side option to forbid him , Dark Side option to encourage him , or a neutral option to leave the decision to Torian , which gains his approval and leads to him firing the guns anyway , killing Chorn and his men . The second is whether to share factory schematics with Shae Vizla before the assault , with the Light Side option leading to Mandalorian victory and the Dark Side option resulting in their defeat , with many warriors including Dalash Ard dying while navigating the maze of factory tunnels , and the remainders being too few to carry a sufficient amount of weapons . In the aftermath , if the battle was victorious , player can respond to Vizla ' s concerns with a Light Side option encouraging her to stop the clans from endlessly looking for a new war , a Dark Side option encouraging her to attack the player ' s opposing faction ( either Sith Empire or the Galactic Republic ) or a neutral offer to replace Zakuul ' s skytroopers after the war ends . If the Mandalorians suffered a defeat , player can respond with a Light Side option by sharing the responsibility for it and offering Alliance resources and manpower to strengthen the clans , a Dark Side option to further undermine Mandalore the Avenger in front of her warriors , or a neutral option promising that the losses were necessary to beat Zakuul .
