The Inspectorate was an inspection agency within the Galactic Empire. Inspector Thanoth served in the Inspectorate during the time in which he was adjutant to Darth Vader. Thanoth uncovered Vader's plot to kill and overthrow the Emperor, for which Vader killed him. Disgraced Imperial Lieutenant Magna Tolvan was named as Thanoth's legatee, and she was subsequently reassigned to the agency's Coruscant HQ with the rank of Lieutenant-Inspector before she later became Captain-Inspector following the infiltration of Hivebase-1.
