High Inquisitor
From Wookieepedia, the Star Wars wiki.
High Inquisitor was a senior rank in the Inquisitorius, a branch of Imperial Intelligence consisting of dark side Force-sensitives who worked under the command of Emperor Palpatine himself. They were often employed as interrogators, however their primary task was to seek out potential Jedi candidates and Force activity during the height of the Galactic Empire. The only higher rank in the Inquisitorius was that of Grand Inquisitor, who was the head of the Inquisitorius. After the fall of the Empire, many of the surviving Inquisitors joined the Great InQuestors of Justice.
