Mission to Tatooine ( Luke Skywalker ) The mission to Tatooine occurred some time after the events of the Battle of Yavin . Luke Skywalker reluctantly underwent the mission after an Imperial transport capsule was identified to have crash landed on Tatooine . What began as a mission to investigate the capsule was complicated by the news that the transport capsule , along with similar capsules that had fallen on other planets , had caused outbreaks of the highly contagious and deadly Bledsoe ' s disease which were followed shortly thereafter by attacks on nearby Rebel bases . Luke Skywalker and an assigned Rebel contact , a female Ogemite named Anduvil , discovered the connection between these events when Luke was infected with Bledsoe ' s disease . The Empire was using a genetically modified strain of Bledsoe ' s to send secret information on Rebel targets . Luke was cured , and with Anduvil he destroyed the local Imperial garrison base , capturing its commander to ensure their escape from the planet . History . Prelude . During the Galactic Civil War , the Galactic Empire sent various transport capsule s to the planets of Rebel sympathizers . These capsules contained Squill s infected with a genetically modified form of Bledsoe ' s disease , which led to an outbreak . This outbreak undermines the social order of planets suspected of leaning toward the Rebellion . Meanwhile the specific genetic modifications of the disease caused the eyes of the infected to develop discoloration , which could be read as star maps which revealed the locations of secret Rebel bases . These bases could then be attacked by Imperial forces . Meanwhile , after the destruction of the Death Star , Imperial forces managed to consolidate their hold on Tatooine and construct an Imperial garrison base . An Imperial transport capsule containing infected Squills was sent to Tatooine , there to be recovered by Stormtroopers and used to infect the populace . However , Jawas found the capsule first , foiling the plan since Jawa eyes were unreadable . Observers at Anchorhead detected the capsule crash , reporting it to the Rebel Alliance . The Mission . Massassi One of the Rebel Alliance ordered a reluctant Luke Skywalker to abandon his space reconnaissance mission and head to Tatooine to investigate the capsule due to it being designated a Code Grave mission . Luke was initially reluctant to return to his home planet due to having bad memories of his time on the planet , but he eventually agreed , accompanied by C - 3PO and R2 - D2 . Upon exiting hyperspace Luke received a mysterious transmission directing him to Chalmun ' s Spaceport Cantina in Mos Eisley , and a contact named Anduvil of Ogem . Luke soon discovered that the Empire ' s new base on Tatooine had greatly increased traffic and military presence in Mos Eisley . Chalmun ' s cantina still had a strict no - droids policy , so Luke entered alone . He was almost ambushed by a bounty hunter working for Jabba Desilijic Tiure , but was saved by his contact Anduvil . She informed him that his mission was not merely to investigate a transport capsule , but to crack an Imperial intelligence operation and discover the link between the crashed transport capsules , the outbreaks of Bledsoe ' s disease , and the attacks on Rebel bases . Before Luke could learn much more , however , a Jawa in the cantina collapsed . The Bledsoe ' s outbreak had reached Mos Eisley . Fleeing the outbreak in Anduvil ' s landspeeder , Luke guided them to Ben Kenobi ' s hut to discuss their next move . They were attacked by Tusken Raiders who smashed Anduvil ' s Landspeeder , but after defeating the raiding party Luke and Anduvil took their banthas . Anduvil guided them to the Jawa sandcrawler that had first found the transport capsule , only to find Imperial Stormtroopers staring into the Jawa ' s eyes . However , Jawa eyes did not properly show the discoloration of Bledsoe ' s disease , and the Stormtroopers eventually left . Investigating the sandcrawler for an explanation of the strange behavior , Luke was bitten by a Squill . Anduvil sadly informed him that Squills carry Bledsoe ' s disease , and that Luke was possibly infected . Before Luke could come up with a plan , however , the Stormtroopers returned . Upon discovering that Luke had been bitten , the Stormtroopers captured them all and took them to the Imperial garrison base , leaving C - 3PO and R2 - D2 behind in the desert . At the base Luke was delivered to Doctor Kaaldar , who discovered that Luke ' s eyes had become discolored from Bledsoe ' s disease , becoming a star map . Luke and Anduil discovered that the Imperials had been using genetically modified Bledsoe ' s to send coded messages and star charts to many worlds , secretly coordinating attacks on Rebel strongholds . Anduvil begged Kaaldar to give Luke an antidote to the disease , but Kaaldar refused as long as Luke ' s eyes revealed the location of a secret Rebel base . Luke was able to overcome his captors , even in his weakened state , and forced Kaaldar to give him the antidote . Outside the garrison base C - 3PO and R2 - D2 had commandeered the abandoned sandcrawler , and driven it through the main gate of the base . This successfully distracted the Stormtroopers , but led to the capture of the droids . While Luke Skywalker rushed to their rescue and took the Imperial commander hostage , Anduvil sabotaged the ion drive s of the base ' s TIE Fighters . Luke , Anduvil , the droids , and the captured commander fled the base just before the sabotaged ion drives exploded , destroying the garrison base . Aftermath . With the base destroyed , Luke , Anduvil , the droids , and their hostage returned to Mos Eisley . They used Luke ' s starship to escape the planet , with their hostage to guarantee their safety during their return to Yavin 4 . They would force the commander to reveal the details of the Empire ' s scheme , ensuring that Bledsoe ' s disease would no longer serve as a vector for secret Imperial information .
