Imperial Center Oversector
this was the Imperial designation of the area of space dominated by the planet Coruscant, and containing all worlds whose galactic coordinates were positive and began with a zero. The farthest reach of this oversector, sometimes called Sector Zero, was the planet Kiribi. Much of the Deep Core was contained in this oversector, since Coruscant itself did not sit at the exact center of the galaxy, despite its 0,0,0 coordinate designation.
