Mission to the third moon of Concord Dawn During the early rebellion against the Galactic Empire , the rebels Kanan Jarrus and Sabine Wren went on a mission to the third moon of Concord Dawn . Jarrus intended to secure an alliance with Fenn Rau , leader of the Protectors of Concord Dawn , so the rebels could safely pass through the Concord Dawn system — or , if diplomacy failed , destroy the Mandalorians ' Fang fighter s so they could not attack the rebel fleet when it moved through the system . Wren , meanwhile , invoked the Mandalorian code to challenge Rau to single combat as justice for the injuries he inflicted on Captain Hera Syndulla during a dogfight over Concord Dawn . The mission was a success ; the rebels captured Rau , leading him to agree to let the rebels pass through his system . Prelude . In 3 BBY , the Phoenix Cell decided to establish a new route through the Lothal sector . At the recommendation of the Mandalorian Sabine Wren , the rebels visited the Concord Dawn system to seek safe passage from the Journeyman Protector s , a Mandalorian faction that had sided with the Galactic Republic during the Clone Wars . However , the Protectors , under the leadership of Fenn Rau , had aligned themselves with the Galactic Empire and attacked a rebel delegation led by Phoenix Leader Hera Syndulla . Hera was badly wounded during the attack . As a result , the rebels abandoned diplomacy and contemplated military action against the Protectors . Sabine managed to track the Protectors ' Fang fighter s to a base on the third moon of Concord Dawn . Sabine advocated destroying the Protectors ' starfighters in order to eliminate their threat to the rebellion . The Jedi Kanan Jarrus supported Sabine ' s plans but insisted on going alone with the astromech droid Chopper , who piloted the " Phantom " , an auxiliary starship . In secret , Kanan planned to negotiate a second time with Fenn Rau in order to give the Protectors a second chance to join the rebellion as allies . The mission . Diplomacy versus conflict . While approaching the Concord Dawn system , Chopper informed Kanan that Sabine had stowed aboard the " Phantom " . After emerging from her hiding place , Sabine and Kanan discussed their differences . While Sabine was intent on avenging the wrong that Fenn had inflicted on Hera , Kanan still wanted to seek a diplomatic solution to the conflict . In the end , Kanan allowed Sabine to destroy the Fang fighters only on the condition that his peace talks with Fenn failed . Chopper dropped the two rebels outside the Protector ' s camp on the third moon of Concord Dawn before retreating to the skies . After landing , Kanan and Sabine spotted the Protectors receiving supplies from an Imperial shuttle . While Kanan followed Fenn Rau into a building , Sabine headed to the starfighter airfield and began planting explosives onto the Fang fighters . Fenn quickly sensed Kanan ' s presence and allowed the intruder to reveal himself . In an attempt to establish a rapport with Rau , Kanan introduced himself as a Jedi Purge survivor who had taken part in the Third Battle of Mygeeto . Rau had commanded Skull Squadron during that battle and had saved the lives of Kanan , his late Master Depa Billaba , and numerous Clone trooper s . Kanan then attempted to convince Rau to realign the Protectors with the rebellion . However , Fenn refused believing that the rebels had a poor chance of success against the Empire . Meanwhile , Sabine managed to attach explosives to seven of the Fang fighters before she was spotted by two Mandalorian sentries . After identifying herself as a member of Clan Wren ( an enemy of the Protectors ) , Wren invoked her right to seek justice through combat . Kanan ' s negotiations with Fenn were interrupted by news that his men had captured another intruder who had invoked the rite of justice through combat , an ancient Mandalorian tradition that had not been invoked during the Age of the Empire . Fenn led a reluctant Kanan to the airfield where the duel was to take place . An explosive showdown . Despite Kanan ' s calls for restraint , Sabine was adamant on proceeding with her plan and urged the Jedi to trust her . Before the duel , Sabine condemned Fenn for attacking and wounding Hera . Rau admitted attacking Hera but insisted that it was not personal . As Fenn drew his blaster pistol , Sabine shot it out of his hand and blew up seven of the Fang fighters with her explosives . Kanan and Sabine then exchanged fire with the Protectors during the ensuing skirmish . Meanwhile , an enraged Fenn climbed aboard the remaining Fang fighter and attempted to attack the rebel fleet . However , Kanan managed to grab onto the starfighter as it climbed into the skies . Despite Fenn ' s efforts to shake off the Jedi intruder , Kanan managed to use his lightsaber to slice through the cockpit and disable the control console . Meanwhile , Sabine rendezvoused with Chopper and the two flew into the skies to pick up Kanan . Following a fist fight , Kanan managed to knock the Protector of Concord Dawn unconscious and carry him onto the " Phantom " . Once aboard the " Phantom " , the three rebels headed back to rejoin the Phoenix fleet in space . As soon as Rau began to stir , he was contacted via comlink by his men . Kanan ordered Fenn to answer the comlink . By that point , the Protectors had amassed reinforcements and were preparing to pursue the rebel intruders . However , Fenn ordered them to stand down and to allow the rebels safe passage through the Concord Dawn system . He also instructed them to hide his capture from the Empire . Aftermath . Fenn Rau accompanied Kanan and Sabine back to the Phoenix fleet where he was taken into custody by the rebels . Due to his combat skills and training , the rebels regarded Fenn as a " reluctant recruit . " Fenn himself regarded the arrangement as an " alliance of necessity . " Sabine ' s conduct during the mission won her the praise of Hera , who praised the younger rebel for finding an acceptable way to resolve the Concord Dawn impasse . By demonstrating their strength , the Phoenix rebels were able to establish a new lane to the Lothal sector that went through the Concord Dawn system . Behind the scenes . The mission to the third moon of Concord Dawn served as the climax of the " Star Wars Rebels " episode " The Protector of Concord Dawn " , which premiered on Disney XD on January 27 , 2016 .
