Sullustan Resistance The Sullustan Resistance was a guerrilla movement by the native population of Sullust against the Galactic Empire between approximately 2 BBY and 4 ABY . History . It all began in the year 2 BBY ( Sullustan Year 8 , 494 ) when Siin Suub , Chairman of the SoroSuub Corporation illegally took over control of Sullust in the name of SoroSuub , and announced that , as SoroSuub was a firm supporter of the Empire , Sullust itself also became one . Many Sullustans , traditionally loyal to SoroSuub , were furious at this decision . The angry Sullustans found a leader on politician Sian Tevv , who had chosen not to join the Rebel Alliance . Nevertheless , Tevv managed the growing Sullustan Resistance movement against the Empire . They staged different attacks against SoroSuub ' s assets , becoming so dangerous that SoroSuub had to create the Sullustan Home Guard to protect themselves against the resistance movement . However , the Home Guard was composed only by native Sullustans , many of whom disagreed with SoroSuub ' s pro - Imperial stance ; thus , the Home Guard was not effective when dealing with the resistance movement . This , added by the courage and dedication of many resistance fighters like Nien Nunb , became a menace for SoroSuub . SoroSuub was forced to call for Imperial reinforcements at least in one occasion under attack of the resistance movement . The opportune arrival of an " Imperial " - class destroyer changed the tide of that battle , turning a sure victory for the resistance movement into a sound defeat , where Nunb lost his ship . At this stage , a great amount of individual anti - Imperial Sullustans were joining actively the Rebel Alliance and not the Sullustan Resistance ( including some important desertions , like Nunb ' s ) . However , Tevv was firm in his decision : The Sullustan Resistance would not join the Alliance at that moment , probably because he feared Imperial retribution . Tevv ' s resistance movement was strong enough to take control of Sullust shortly before 0 BBY . At this stage , SoroSuub understood that neither the Empire nor themselves could fight any longer the piracy and sabotage of the resistance movement . SoroSuub finally sided with the Rebellion , but Sullust did not for a little longer . The Empire , as part of Operation Strike Fear , was planning a possible invasion of Sullust . They captured Sullustan technical staff and leaders and were transporting them to Coruscant for probable interrogation , torture and servitude . Hoping to persuade the Sullustans to join the Alliance , the Rebels mounted a rescue operation . After the rescue Sullust agreed to enter negotiations with the Alliance . A diplomatic meeting near Sullust was interrupted by the arrival of the " Imperial " - class Star Destroyer " Invincible " . The Rebel pilots , Hamo Blastwell and Keyan Farlander , flying R - 22 Spearheads , held off the Imperial fighters until the meeting was concluded and all ships fled into hyperspace . The " Invincible ' s " attack , however , turned out to be merely a diversion . While the meeting was taking place , stormtroopers kidnapped the Sullustan leader Sian Tevv . Farlander and Blastwell were called into action again to disable the shuttle that bore him to the " Invincible " and hold off Imperial fighters until a Rebel shuttle conducted a boarding operation and escaped into hyperspace . After the Rebel ' s recent assistance , Sullust agreed to become an ally of the Rebel Alliance , but not a full member . However , the rescued Sullustan technical staff worked together with General Crix Madine to devise a plan to end Operation Strike Fear by destroying the " Invincible " . The Rebels captured some engineers from Cygnus Corp and had them modify a shuttle to appear to be an Imperial vessel . Then , disguised as suppliers delivering cargo , Rebel agents got aboard the " Invincible " and planted a stolen Imperial warhead . The warhead exploded shortly after they left , destroying the " Invincible " . Tevv later allowed the Rebel fleet to meet at Sullust , endpoint of the Sanctuary Pipeline , to plan the destruction of the Death Star II . After the Battle of Endor in 4 ABY , Tevv would finally join the Alliance , bringing with him a great amount of Sullustan rebels and becoming one of the signatories of the Declaration of a New Republic . The Sullustans became active members of the New Republic , and there was no more need for a Sullustan resistance movement .
