The personal headquarters of Grand Admiral Thrawn, an Imperial officer, were known as Thrawn's Offices. Aboard his flagship, the Star Destroyer Chimaera, was his primary office location; however, he maintained a secondary office within the Imperial Armory Complex as well. Within these spaces, Thrawn frequently studied artistic works and various pieces of evidence, all in pursuit of his objective to crush the rebellion.
Adjacent to Thrawn's office was a training facility, which housed a pair of DT-series sentry droids. These droids were utilized by the Grand Admiral for physical training and martial arts practice, as Thrawn believed that physical fitness had a direct and positive impact on mental acuity.
