Tula Tula was a human female who served as an officer of the Galactic Empire during the Galactic Civil War , even after the Imperials destroyed her homeworld of Alderaan . Tula manipulated her sister , Tace , into providing the Empire with intelligence on the activities of Prince ss Leia Organa , who was attempting to rescue the survivors of Alderaan . Organa became aware of Tula ' s manipulation of Tace after Imperial forces attacked the princess while she visited the Alderaan Enclave on the planet Sullust . Organa then had Tace try and question her sister , but Tula ' s commanding officer , Dreed , realized what was happening and had Tula taken away by stormtrooper s for processing . Organa negotiated with Dreed to exchange herself for Tula on the planet Skaradosh , but once there , the princess had her allies swoop in and kill Dreed and his men . Tula was then reunited with her sister but found Tace angry over her betrayal . The sisters were reconciled to some extent during a battle between Dreed ' s Star Destroyer and the Alderaanians gathered by Organa above the planet Espirion , which ended in the Imperial vessel ' s destruction . Biography . Betraying her people . The human sisters Tula and Tace were both born on the planet Alderaan but chose very separate paths in life : Tula came to serve as an officer of the Galactic Empire during its war against the Rebel Alliance , while Tace joined the cloistered music al group known as the Melodic Order as a musician . In the year 0 BBY , during Tula ' s service to the Empire , Alderaan was destroyed by the Imperial Death Star superweapon ; however , she continued her Imperial service obediently . Tace , meanwhile , initially remained unaware of her homeworld ' s fate , as her employers at Club Deeja on the planet Naboo decided their musicians would perform better without such terrible news . Tula ' s sister finally learned the truth in the year 0 ABY , shortly after the Battle of Yavin , when Leia Organa , Prince ss of Alderaan , rescued the Melodic Order from the club as part of her mission to rescue the survivors of Alderaan from Imperial persecution , then invited them to join her mission . Once off Naboo and aboard Organa ' s starship , the " Lord Junn " , Tace used a video call to contact Tula , who was serving on the " Imperial " - class Star Destroyer of Commander Dreed . Unaware that her sister was an Imperial , Tace tried to arrange for the sisters to meet up and mourn , but Tula , seeing an opportunity to gain intelligence on the fugitive Alderaanian s ' activity , told Tace that it was her duty to stay with Organa and aid her . She then asked that Tace contact her every day with an update on her location and activities , so that the pair could " keep in touch . " Tace did as Tula asked and frequently updated her on Organa ' s activities , letting her sister know when Organa traveled to the planet Sullust to make contact with the Alderaan Enclave located there . Tula immediately passed on the information to Dreed , who was impressed by her manipulation of Tace , but Dreed warned Tula that he was ready for her to betray him given her emotional bond with her sister . Meanwhile , on Sullust , a resident of the enclave named Covis discovered the communications between Tula and Tace and reported them to Preserver Jora Astane , head of the enclave . Astane accused Organa herself of betraying the Alderaanians to the Imperials and had her chased from the enclave . As the Alderaanians tried to hunt down Organa , a " Sentinel " - class landing craft full of stormtrooper s sent by Dreed arrived and attacked the enclave . Ultimately , Organa saved the enclave and defeated the trooper s using a herd of rockrender s , earning Astane ' s loyalty and escaping Sullust . A traitor revealed . Unperturbed , Dreed continued to use Tula to get information from Tace ; however , with the Alderaanians now aware of the siblings ' communications , Tace was imprisoned by Astane and questioned by Organa . The princess believed that Tace had not known about Tula ' s Imperial loyalty and asked that she contact her and try to learn about her sister ' s location and situation . Once the call began , Tula almost immediately realized something was wrong , as did Dreed , who saw that the facade was over . Despite Tula ' s pleas that she could fix the situation , the commander ordered that she be taken away for processing , as she was no longer of any use to him . He then turned to the communications console and accused Tace of being responsible for what was going to happen to her sister . Organa herself then took Tace ' s place on the video and asked the commander to consider an exchange for Tula . Dreed was initially uninterested until the princess agreed to his demands that she trade herself for Tula . The exchange was arranged to take place on the desert world of Skaradosh , and Dreed accompanied Tula personally aboard a " Lambda " - class T - 4a shuttle to the planet ' s surface . Upon meeting with Organa , the commander questioned why Tula was so important but refused to believe the princess ' s claim that all Alderaanians were important enough to be worth saving . Although not satisfied with the answer , Dreed sent Tula forward to Organa ' s escort , while the princess crossed over to the Imperials . As the pair passed each other , Tula tried to thank Organa , but her savior only commented that Tula needed to do better in return for being saved . Before either party could return to their ships , Organa ' s pilot , Evaan Verlaine , and the smuggler Nien Nunb swooped down in the freighter " Mellcrawler " and opened fire on the Imperials . Dreed and his stormtrooper escort were killed , and Organa safely boarded the freighter alongside Tula and the other Alderaanians . An unhappy reunion . Now under the command of Captain Venk , the crew of Dreed ' s Star Destroyer quickly became aware of their commander ' s death but were tricked into believing that they had killed those responsible after shooting down a decoy sent from Skaradosh by Nunb . The " Mellcrawler " , meanwhile , escaped the desert world unscathed and headed for the planet Espirion , where Tace and the other Alderaanians awaited them aboard the " Lord Junn " . En route , Organa was horrified to discover that Dreed ' s Star Destroyer was also heading for Espirion , as the Imperials were aware of the Alderaanians ' presence there from intelligence Tula had previously given to Dreed . The " Mellcrawler " arrived at the planet first , giving the ship time to dock with the " Lord Junn " and allowing Tula to be reunited with her sister . The former Imperial was overjoyed to see her sibling , but the feeling was far from mutual , as Tace wanted nothing to do with her sister , whom she considered a traitor , and Tace had even shaved off her hair in order to look less like her . Tula tried to apologize and claimed that they could go back to how things were before Alderaan ' s destruction , but Tace stormed off , leaving her sister to try and keep up . Nonetheless , the sisters were soon brought together when the " Lord Junn " and the rest of the Alderaanian fleet came under attack from Dreed ' s Star Destroyer as it reached Espirion . Amidst the chaos of battle , Tula and Tace clutched each other in fear , as Organa delivered what she thought might be her final speech to all those Alderaanians who fought alongside her . However , the fleet was saved when reinforcements arrived in the form of the " Espirion Multi " , a starship sent by the Alderaanian - descended inhabitants of Espirion , known as Alder - Espirions , after they heard Organa ' s passionate speech . Their combined forces then destroyed the Star Destroyer . Personality and traits . Tula had black hair , dark eye s , and light skin . Tula and Tace shared a close bond as sisters , and each was able to tell if the other was lying or speaking under duress , with Tula instantly noticing when Tace spoke to her with lines prepared by Princess Leia Organa . Tula was a highly obedient individual , according to Imperial personality tests , and continued to serve the Empire even after it destroyed her homeworld . She went so far as to manipulate her own sister to gain intelligence for Commander Dreed concerning the movements of Organa , princess of Alderaan . Despite this obedience , Dreed still expected the officer ' s betrayal , as Tula scored low on tests for loyalty to the Empire and still clearly loved her sister . Ultimately , Tula did not have a chance to betray the Empire , as Dreed decided her usefulness had run out once the Alderaanians realized she was manipulating Tace . When Organa saved Tula from the Imperials , she attempted to thank the princess and , upon being reunited with Tace , tried to apologize for what she had done . She hoped that her and Tace ' s relationship could return to what it was before her betrayal , but Tace expressed uncertainty in their reconciliation . Equipment . While serving the Empire , Tula wore a standard gray Imperial officer ' s uniform . Sometimes , when contacting Tace under the guise of being off duty , she wore a black outfit instead . Behind the scenes . Tula first appeared in the second issue of the " " comic book mini - series , going on to appear in all remaining issues of the run .
