Mission to Monastery In 0 ABY , a mission was carried out by Luke Skywalker in an effort to convince the isolationist Order of the Sacred Circle to join the Rebel Alliance . However , it was soon discovered that the mission was a trap set up by the Dark Lord of the Sith Darth Vader to test Skywalker ' s skills . The mission began when the leader of the Order , Domina Tagge , tricked by Vader and acting on his orders , asked the Rebellion to send one of its heroes , Luke Skywalker , to the planet Monastery as an envoy . General Jan Dodonna agreed and also sent Princess Leia Organa , who was later captured by Imperial forces but managed to escape . Meanwhile , Skywalker met Vader and was forced to accept a duel with him . However , before the duel began , Organa had unwittingly brought Domina ' s brother and former baron of the House of Tagge , Orman Tagge to Monastery . Vader used Tagge to test Luke ' s mastery of the Force by making him appear to Skywalker as the Dark Lord of the Sith himself . Skywalker killed Orman Tagge , and , realizing that he was not ready to fight the real Vader , escaped on the " Millennium Falcon " . Prelude . After learning that the pilot who destroyed the Death Star during the Battle of Yavin was his own son Luke Skywalker , a Rebel hero , Dark Lord of the Sith Darth Vader planned to set a trap for him . Vader tricked Domina Tagge , a member of the Order of the Sacred Circle located on Monastery , into cooperating with him , promising power and prestige . Tagge also craved revenge against Skywalker , for she believed her brother , Orman , was killed by him in a battle with the Rebels over the Feswe Corridor . In fact , Orman had been only wounded during the battle and rescued by Vader afterward . Vader , who had been keeping Orman Tagge in hibernation since then , had his own plans for this mission ; he planned to use it as a test for his son and to lure him into the fight he was not ready for . Not long after , Skywalker saved a civilian vessel from an Imperial attack and escorted it to the Rebel base on Yavin 4 . Aboard that vessel was Domina , who informed the Rebels that her homeworld of Monastery — which had stayed neutral throughout the course of the war — was willing to join someone . To decide between the Alliance and the Empire , she requested that both sides send an envoy to Monastery and asked Skywalker to go . The Alliance agreed and sent him along with his droid R2 - D2 . However , since Skywalker did not have much skill in diplomacy and only one representative from each side was allowed , General Jan Dodonna — commander of the Yavin Base — also secretly sent princess Leia Organa , former smuggler - turned - Rebel Han Solo , protocol droid C - 3PO and Solo ' s co - pilot Chewbacca , on the " Millennium Falcon " to make sure that everything would proceed smoothly and to help Skywalker if needed . The mission . Contacting the Order . As soon as Skywalker landed , he was attacked by a Nightshrike , a native beast on Monastery . After defeating it , he met Darth Vader , who was acting as the representative of the Empire . Skywalker wanted to attack him , but remembering his promise to keep the mission peaceful , agreed to meet Vader another time after the mission . Meanwhile Organa and Solo established a laserwave link with R2 - D2 to monitor his activities . However , the " Falcon " was soon captured by an Imperial Star Destroyer under the command of Captain Mulchive Wermis , who was informed by Vader that the Alliance would also send Princess Organa on the mission . Wermis ordered a search of the ship but did not find the princess . Nonetheless , he imprisoned Solo and Chewbacca , but Organa , who was hiding in the ship ' s smuggling compartments , decided to rescue them and warn Skywalker . She contacted him via R2 , and tried to inform him that the mission was a trap . However , Skywalker interrupted the transmission when Domina appeared and told him that the Order was ready to make a decision . She then escorted him to the main chambers and said that the Order had decided to join the Empire in an effort to eliminate the Rebel Alliance . Skywalker tried to attack Vader , whom he suspected of using the Force to cloud Domina ' s mind , but she said that this was not the time to fight and proposed a place to settle their dispute . Meanwhile , aboard the Imperial ship , Princess Organa , using proton grenade s to set a distraction , managed to free Solo and Chewbacca . After they escaped from the ship , they discovered that their long - time enemy and former baron of the House of Tagge , Orman Tagge — who had previously aided Imperial efforts against the Rebellion — managed to break free from his life support capsule where he had been kept hidden from his sister by Vader in perpetual stasis . Orman sneaked aboard the " Falcon " and , believing that his sister was in danger , decided to rescue her . By threatening Solo and Organa with a blaster , he ordered them to pilot the ship to the surface of Monastery . Skirmish in the Crystal Valley . As Vader was approaching the ceremonial Crystal Valley , a place proposed by Domina to fight Luke and an exceptionally dangerous territory in a constant state of eruption with pillars of crystal falling and coming up through the ground , he noticed the " Falcon " preparing to land . Meanwhile , aboard the ship Organa and Solo were at last able to subdue Tagge , but were soon attacked by pursuing TIE fighters . In the midst of chaos , Orman escaped and ran into the valley . One pillar nearly fell on Tagge , but the former baron was saved by Vader . The Dark Lord explained that killing Tagge would be far too easy and unimaginative , and proceeded to inform the man that his sister was no longer unsullied and uncorrupted . Distraught , Tagge begged Vader to kill him there and then , but the towering Sith Lord had one final purpose for him . He intended to use Tagge as a test for Skywalker . Soon enough , Skywalker fought whom he thought to be Vader in the valley , but when he delivered a final blow , he realized that it was in fact an illusion and he had killed Orman , who had been disguised as Vader by the Force . When the real Vader appeared and told his son that the whole mission was meant to test Skywalker ' s abilities , the young Rebel decided to run , because he felt that the only way to win that battle was to stop playing Vader ' s game . Aftermath . Above the valley , Solo and Organa informed Domina that Vader was lying to her and that Orman had been kept in hibernation the whole time . However , when Skywalker appeared without Orman Tagge and tried to explain what had happened , Domina refused to listen and said that despite the fact that the Order would not join the Empire , her wrath would always be against Skywalker . The young Jedi also realized that with all Vader had learned , he would not be cautious again about attacking him or the Rebels , as he did in their previous encounters . With such thoughts , Skywalker watched as Vader departed Monastery , and then left as well . Behind the scenes .
