Dark Side Adept

Dark Side Adept was a generic term to describe any Force-sensitive Imperial other than Darth Vader and the Emperor himself. Palpatine planned to eventually replace all officials in the Galactic Empire with Dark Side Adepts. The highest ranking Adepts were the members of the Inquisitorius. Other Adepts included the Dark Side Elite, the Clone Keepers, the Imperial Sovereign Protectors, and various Imperial Dark Jedi.
