Mission to Mandalore ( Imperial Era ) The Mission to Mandalore was a mission led by the Mandalorian Sabine Wren in 1 BBY during the Mandalorian civil war to rescue her father Alrich Wren from the clutches of the Galactic Empire and their Mandalorian ally Governor Tiber Saxon on the planet Mandalore . Clan Wren managed to rescue Alrich with the help of their Mandalorian allies and the Rebel Alliance Spectres cell . In response , Saxon then unleashed the Arc Pulse Generator known as the " Duchess " against the Clan Wren forces , killing many . Seeking atonement for her role in creating the weapon , Sabine led the Mandalorians and rebels on a mission to infiltrate Saxon ' s Star Destroyer , which was berthed above the capital Sundari . Despite being ambushed by Saxon ' s forces , the Mandalorians and rebel allies managed to destroy the weapon and Saxon ' s flagship . Following the operation , Bo - Katan Kryze inherited the Darksaber and became the new Mandalorian leader . Prelude . During the Imperial Era , the Mandalorian Sabine Wren was an aspiring , talented cadet at the Imperial Academy of Mandalore . She designed a powerful weapon known as the " Duchess " , which was capable of targeting the beskar alloy in Mandalorian armor and incinerating the wearers . Sabine later became disillusioned with the Galactic Empire and joined the Spectres rebel cell , which later joined the Alliance to Restore the Republic . She came into possession of the Darksaber , an ancient symbol of Mandalorian leadership , after finding it in the Nightsister lair on Dathomir . The weapon had previously been in the possession of Darth Maul , a Sith Lord who had taken over Death Watch , a Mandalorian faction formerly led by Pre Vizsla that had overthrown the pacifist Duchess Satine Kryze in order to rule the planet late in the Clone Wars . Maul had been forced out of power and made to flee after the Siege of Mandalore and the rise of the Empire . After reconciling with her family and defeating the Imperial puppet Governor Gar Saxon , Sabine managed to win over her clan to the rebel cause . However , she learned that her father , Alrich Wren , had been taken hostage by the Empire in order to ensure Clan Wren ' s cooperation . Sabine earned the right to wield the Darksaber by defeating Gar Saxon in single combat when he was wielding it , which technically made her Mandalore ' s rightful leader . However , she did not want the responsibility , and vowed to pass on the sword to someone who could lead Mandalore . In return , Clan Wren helped Phoenix Cell and the Spectres escape the Battle of Atollon and regroup . Sabine then agreed to return a favor to her mother Ursa Wren , as the clan was locked into a civil war with the Imperial – allied Clan Saxon . While the Rebel Alliance was unable to send forces to aid Clan Wren , Phoenix Leader Hera Syndulla allowed Sabine to return and aid her family . Sabine was joined by several of her Spectres ' comrades , the Jedi Knight Kanan Jarrus , Jedi Padawan Ezra Bridger , and Chopper . The Spectres members , as well as the Mandalorian forces that had gone to Atollon , split up with the remaining Rebel ships in deep space . Ezra ' s " Gauntlet " and the Fang fighter s headed for Mandalore , while the Rebel ships went to Alliance headquarters on Yavin 4 . Due to the Spectres being an asset to the Alliance , Hera had a difficult time persuading Mon Mothma to allow two - thirds of her crew to leave , and they were under orders to return after Sabine ' s father had been rescued . The mission . Attack on an Imperial outpost . In 1 BBY , Clan Wren , the Spectres , Lady Bo - Katan Kryze , warriors from Clan Kryze , and the surviving Journeyman Protector Fenn Rau undertook a mission to rescue Alrich Wren from Imperial custody . After receiving information from spies in Sundari , the capital , that Alrich was being held at an Imperial outpost , Sabine and her comrades launched a surprise attack on the outpost , led by Sabine wielding the Darksaber . During the attack , the Empire deployed Jumptrooper s and All Terrain Attack Pod s , but were all ultimately defeated . After clearing the outpost , however , Alrich could not be found , and Sabine , Rau , Bridger , and Jarrus met with Kryze , the former regent of Mandalore . Sabine attempted to recruit Kryze as the new wielder of the Darksaber and Mandalore ' s new leader . However , Kryze declined , since Clan Saxon had conspired with the Empire to depose her and she felt that she had already had her chance to rule . Sabine made contact with her mother , who informed her that the Imperials were transport ing Alrich back to the capital for a public execution . Sabine and her comrades devised a strategy to intercept the Imperial convoy that was transferring her father before it could reach the capital . Rescuing Alrich Wren . The convoy consisted of three Imperial Troop Transport s , escorted by several scout trooper s on speeder bike s , and several Imperial Super Commando s that were riding on the transport carrying Alrich . The convoy was led by Captain Hark , who had been receiving his orders directly from Governor Tiber Saxon . A plan was made to separate the middle ITT carrying Alrich from the rest of the convoy , in order to isolate it and make it easier for someone to board it and rescue Alrich . Bridger volunteered , and the rebels soon ambushed the convoy . Sabine fired a paint bomb which smeared the window of the middle ITT , while the other rebels took out the other transports , stormtrooper s , scout troopers , and Imperial Super Commandos . During the attack , Bridger infiltrated the ITT holding Alrich and rescued him , forcing Hark to escape . While the convoy was clear , the now - pilotless ITTs were drifting towards a cliff overlooking a canyon . Unfamiliar with the Mandalorian jetpack s , Bridger gave his to Alrich and while Alrich escaped , Bridger Force jump ed out of the transport towards the cliff . He almost missed his grip , but Sabine managed to grab his hand . Hark contacted Saxon , informing him that Alrich had been freed . However , Saxon told him not to worry since he would be deploying their new weapon . After a brief reunion with her father , Sabine contacted her mother who , along with Sabine ' s brother Tristan Wren , had engaged Imperial forces and forced them to retreat . Massacre on Mandalore . However , while all Imperial forces were in full retreat , Tristan informed the others that a " Gozanti " - class cruiser had deployed what seemed like a modified AT - DP , which soon began charging up its primary weapon . Sabine , listening through Rau ' s comlink , recognized the sound as the Arc Pulse Generator , the weapon she had designed during her time at the Imperial Academy , which she had named the " Duchess " after the late Satine Kryze . She tried to warn her mother and brother to get off the battlefield , just as the weapon began firing . Sabine , her friends and fellow Mandalorians soon arrived at the site of the battle , and saw nothing but what remained of the defeated . Many bodies were left vaporized by the weapon , with only their scorched Mandalorian armor left remaining . Sabine , not being able to locate her mother and brother , feared the worst , and fell to her knees in tears . While the others were discussing what kind of weapon could do such damage , Sabine blamed herself for designing the weapon that had killed her mother and brother . However , just as Sabine was losing hope , she heard her brother yell for her , and saw them emerge from behind the wreckage of an ITT , wounded but still alive . Relieved , Sabine reunited with them , but just briefly , as Imperial aerial forces including Jumptroopers , Imperial Super Commandos , and TIE Fighters arrived to finish the survivors off . A Clan Kryze affiliated " Kom ' rk " - class fighter came from behind the TIE fighters , shooting one down , and rescued the group . As the " Kom ' rk " - class fighter was making its escape , it was hit by a TIE fighter , causing it to lose some power and its weapons systems . While Sabine repaired the ship ' s systems , Kryze and Bridger launched from the ship and engaged the TIE fighters . After destroying the remaining two , they returned to their ship , and made for their camp . Mission to Sundari . As Sabine and the others landed at a camp , Clan Kryze warriors threatened to kill Sabine for her role in creating the weapon . They accused her of betraying her fellow Mandalorians . However , Sabine owned up to her mistakes and Kryze managed to convince the others that Sabine would destroy the " Duchess " . The Wrens , Jarrus , Bridger , Rau , and Kryze met at the command center to discuss a strategy for destroying the " Duchess " . Kryze and Rau discussed on the sidelines while observing Sabine , that she should lead Mandalore . Alrich believed that Saxon would keep the " Duchess " in the most secure place on Mandalore , aboard his own " Imperial I " - class Star Destroyer , which was docked outside of Sundari . Sabine and Kryze would find the " Duchess " and destroy it , while Bridger , Jarrus , and Chopper would find and erase all memory of the weapon from Imperial systems and Rau and the remaining Mandalorian warriors diverted Imperial reinforcements to their location . They infiltrated the Star Destroyer via jetpack during the night through the hangar bay but they were noticed by a TIE fighter pilot . The Mandalorians and rebels were then attacked by Imperial stormtroopers . Sabine , noticing that the arc generator was not mounted on the " Duchess " , deduced that they must have moved the arc generator to a more secure location . She and Kryze found the arc generator in a control room overlooking the hangar bay . Before Sabine could disable it , the weapon fired in low power mode , knocking her and Kryze to the ground . Saxon and Hark revealed themselves with Saxon demanding that she upgrade the arc generator to full capacity or he would kill Kryze . When Sabine refused and Hark warned that the Empire could use the weapon against all Mandalorians , Saxon fired the arc generator at Hark , Sabine , and Kryze . Meanwhile , AT - DPs were engaging Rau and Mandalorian warriors . Elsewhere , Bridger , Jarrus , and Chopper reached the databank s and Chopper began erasing all data . Bridger attempted to contact Sabine but received no response . Jarrus then sent her to help Sabine while he and Chopper finished erasing the data . Bridger entered the hangar and found Rau in the middle of a firefight . Rau sent Bridger towards the control room where Sabine and Kryze had headed . Meanwhile , Saxon managed to force Sabine to upgrade the arc generator despite Kryze ' s pleas . However , Sabine modified the arc generator to to target the material found in stormtrooper armor , which Saxon was also wearing . This had the effect of incapacitating Saxon and the stormtroopers . , which allowed Hark to escape . With the tables turned on Saxon and the Empire , Sabine vowed to kill Saxon but Kryze managed to restrain her by telling her to be better than the Empire . Heeding Kryze ' s words , Sabine activated the Darksaber and sliced through the arc generator just as Hark escaped and Bridger arrived to help . As the arc generator overloaded , Sabine , Kryze , and Bridger met up with Jarrus , Rau , and the others in the hangar , escaping with their jetpacks just as the arc generator exploded , engulfing the Star Destroyer soon exploding and sending it crashing down towards the surface . Aftermath . At dawn , they arrived back at their camp . During the return journey , Kryze warned Sabine and Ursa that Mandalore would now face the full might of the Empire . After landing , Sabine stated that Kryze should lead them . When Kryze countered that Sabine had made the difficult decisions , Sabine thanked her for guiding her and told Kryze that she was worthy of wielding the Darksaber . Sabine added that the other clans shared her opinion that Kryze was a worthy leader . The various Mandalorian clans Clan Vizsla , Clan Rook , Clan Eldar , Clan Kryze , Rau representing the Journeyman Protectors , and Clan Wren all pledged allegiance to Kryze , who accepted her position on behalf of her sister , her clan , and all of Mandalore . Shortly afterwards , Sabine , Ezra , Kanan and Chopper returned to the Rebellion , travelling to Yavin 4 on Ezra ' s " Gauntlet " .
