Leia becomes Darth Organius

Princess Leia Organa was trying to deliver the Death Star plans to the Rebel Alliance. Leia's ship was being pursued by Sith Lord Darth Vader aboard his Star Destroyer, the Devastator. Darth Vader boarded the Devastator and captured Leia. Leia put the Death Star plans in R2-D2 and told him and C-3PO to find Jedi Master Obi-Wan Kenobi on Tatooine. Vader brought Leia to a very angry Grand Moff Tarkin. Tarkin demanded that Leia disclose the location of the hidden Rebel base or he would fire the Death Star's superlaser on her home planet of Alderaan. To save her people, Leia told Tarkin that the base was on Yavin 4. Tarkin was pleased. He decided to spare Alderaan. Darth Vader, also pleased, then took Leia as his secret Sith apprentice after revealing to Leia that he was her father. Vader then bestowed upon Leia the Sith title "Darth Organius". Vader then ordered Organius to kill the Rebels.
