Eight months into that year , the Sith Lord Darth Vader of the Galactic Empire paid a visit to Si - Di - Ri and the League , which acted as the government of Tiss ' sharl , forcing them to lower the prices of the TaggeCo blaster cartridges they sold to the Empire . Following a failed assassination attempt against Si - Di - Ri , Vader used the President to lure out a representative from the Alliance to Restore the Republic , as Si - Di - Ri was dealing with the Alliance in light of the price cuts the Empire demanded . After figuring out that Vader had used him , Si - Di - Ri realized that everyone had a higher master , even a president . He then resigned as the head of the Tiss ' sharl League . Biography . A male Tiss ' shar , Si - Di - Ri was the President of the Tiss ' sharl League , the planetary government of the world Tiss ' sharl , by 0 ABY , at the time of the Galactic Civil War between the Galactic Empire and the Alliance to Restore the Republic . Assassinations commonly shaped politics on Tiss ' sharl , and Si - Di - Ri used them to get himself to the presidential position , although he still managed to make Vice President Astre - De - Kay one of his good friends . Though the League was allied with the Empire , Si - Di - Ri was secretly sympathetic to the Alliance ' s cause , and he supplied the Rebels with Tiss ' shar technology through the Rebel Timi Rotramel , a Mon Calamari senator . Eight months into 0 ABY , during a bout of assassinations in the Tiss ' sharl League , the Sith Lord Darth Vader of the Empire arrived on Tiss ' sharl to introduce the planet ' s new Imperial Liaison , Commander Demmings . When Si - Di - Ri ' s personal chef , who prepared the dinner for the two groups , complained that Vader would not be eating at the event , Si - Di - Ri chastised him in front of the Dark Lord . Si - Di - Ri attended the dinner and was accompanied by other League members , such as Vice President Geor - Dan - Thi . The Vice President had rapidly risen to his rank following a series of assassinations that had paved the way for his current position after they killed off certain Tiss ' shar , including Astre - De - Kay . At the dinner , Vader introduced Demmings and then required the League to lower the prices of the TaggeCo blaster cartridges they sold exclusively to the Empire , an act he had done twice before that year . Vader gave them a day to comply , and also commented that Si - Di - Ri was to not be harmed or targeted for lowering the prices . In the night , Si - Di - Ri was attacked by a Tiss ' shar assassin while he was on the balcony of his residence . The President was shot in the shoulder , though his guards managed to drive off the assassin . In the morning , Si - Di - Ri left alone from the residence and was briefly confronted by a Tiss ' shar at the doorway , who asked where he was going . Si - Di - Ri then made his way to a meeting with Rotramel , who was then a former senator after the Empire had discarded the Imperial Senate . There , Rotramel offered to set up an Alliance base on Tiss ' sharl and protect the planet from the Empire in order to keep intact Tiss ' sharl ' s economy , though Si - Di - Ri wondered at the feasibility of that option . Vader soon interrupted the meeting , after being informed of the President ' s leaving by the Tiss ' shar who had earlier asked Si - Di - Ri where he was going , and killed Rotramel . Vader complimented Si - Di - Ri on bringing the Alliance representative to him , and let Si - Di - Ri keep the current price for the blaster cartridges , as the lowering of the price had been meant to force Si - Di - Ri to deal with the Alliance and thus draw a representative to Tiss ' sharl . Later , after realizing that , despite his climb to the top of the Tiss ' shar ladder , there would always be a greater master pulling the strings , and that his loyalty to the Empire might one day be questioned , Si - Di - Ri chose to take the extremely unorthodox step of resigning as president . He declared his intention in front of the other members of the League and was succeeded by Geor - Dan - Thi . Personality and traits . An orange - eyed , gold - skinned Tiss ' shar , Si - Di - Ri was a master of finance who was able to rise to the position of president , though this rise was aided by the use of some political assassinations . The Tiss ' shar was also knowledgeable on the political scene of his planet and was worried about Geor - Dan - Thi ' s rise . Despite the Tiss ' sharl League ' s allegiance to the Galactic Empire , Si - Di - Ri was covertly sympathetic to the Alliance ' s cause and even supplied the Alliance with Tiss ' shar technology through Rotramel . After the bouts of assassinations and the attempt against him , Si - Di - Ri soon began to feel that his current state of well being was only temporary , and he wondered if the League had always had so many assassinations . Although Darth Vader warned the other Tiss ' shar of the League that no repercussions of the lowering of the price should be aimed at the President , Si - Di - Ri knew his promise was meaningless , as betrayal was as common in the Empire as it was in the League . The President also considered himself defiled just because he laid eyes upon Vader . The encounter with Vader and the death of Rotramel caused Si - Di - Ri to resign , because he realized that no matter how far he climbed up the political ladder , there would always be a greater master . Another reason for Si - Di - Ri ' s resignation was because he was not sure how long he could maintain the ruse of loyalty to the Empire . Behind the scenes . Si - Di - Ri first appeared in " " , a Dark Horse comic book that was written by Scott Allie , illustrated by Joe Corroney , and published in 2005 . He later received his own entry in " The Complete Star Wars Encyclopedia " , released in 2008 .
