Grand Inquisitor was a rank used within the Galactic Empire, which utilized Inquisitors in order to hunt down and destroy Jedi who had survived the Jedi Purge. The Pau'an male[5] known only as the Grand Inquisitor, who was once a Jedi Temple Guard, held the title of Grand Inquisitor and reported to Darth Vader,[4] a Dark Lord of the Sith and apprentice to the Emperor, Darth Sidious. He was higher ranked than other Inquisitors, such as the Seventh Sister and the Fifth Brother, and was trained in the arts of the dark side of the Force and lightsaber combat. In order to understand his Jedi opponents, he studied the records of the Jedi Archives from the Imperial Palace —which had previously been the Jedi Temple. This gave him an advantage in combat, as he was able to understand Jedi fighting styles.
