Oversector

An Oversector was a division of galactic territory utilized by the Galactic Empire, comprised of many sectors. A Grand Moff led an Oversector, appointed personally by the Emperor. A Grand Moff superseded the authority of his constituent Moffs, planetary governors, and other local authorities as a means to further combat the growing Rebellion and other criminals, whom had been able to escape imprisonment by escaping into another Sector where a Moff was unable to deploy his forces to. Thus, Grand Moffs were created, at 's recommendation, to use every resource to combat the Rebellion.

At the Empire's height, there were many Oversectors. However, with the utter collapse of the Imperial state in 4 ABY, followed by years of civil war and territorial loss, the number of Oversectors dwindled vastly. With the reorganization of the Empire under Vastir Tokrev and his successors, the number of Oversectors is few, ranging anywhere from three to a dozen. This was done as a means to compensate for the vast loss in military forces and men worthy of the prestigious title.
