During the Great Jedi Purge, the Galactic Empire embarked on a hunt during the early years of the Imperial Era for the rebel network known as the Hidden Path, which helped to smuggle surviving Jedi and other Force-sensitives away from the Empire. In 9 BBY, it became tied to the hunt for Jedi Master Obi-Wan Kenobi when he allied himself with the Path to rescue Princess Leia Organa. While they escaped, the Third Sister placed a tracking device on them to lead the Empire to both Kenobi and the Path.
