The assignment to locate Princess Leia involved Jedi Master Obi-Wan Kenobi traveling to the planet Daiyu in 9 BBY, amidst the Great Jedi Purge. This mission was initiated by a request from Bail Organa for Kenobi to save Leia Organa, who had been kidnapped by the Third Sister in an effort to lure Kenobi from his concealed location.
