Expansion Region

The Expansion Region was a region of the galaxy located between the Inner Rim and the Mid Rim. Located within was the Ghost Nebula, which contained the Umbara system. The Expansion Region also included the Cvetaen and Sumitra star systems, and the planets Aquaris, Kerkoidia, Thustra, and Sibensko.

History
During the Clone Wars, the Expansion Region world of Umbara was the site of a prolonged battle in 20 BBY between the Grand Army of the Republic and the native Umbarans, who had aligned themselves with the Confederacy of Independent Systems. Numerous Clone troopers and Umbaran soldiers were killed during the fighting. The Besalisk Jedi Master Pong Krell commanded the 501st Legion during the battle and proved unpopular with his men. After being discovered as a traitor, Krell was executed by Dogma with the approval of the other Clone troopers. The Republic managed to occupy Umbara.

During the Age of the Empire, much of the Expansion Region fell under the jurisdiction of the Galactic Empire, the successor to the Galactic Republic. Following the theft of Moff Wilhuff Tarkin's flagship Carrion Spike, an Imperial comms officer calculated that the Expansion Region planets of Aquaris and Thrusta were the closest sites to the location of the stolen ship while it was at the location sector-designated as LCC-4-4-7. The same officer also estimated that LCC-4-4-7 was located equidistant to the Sumitra and Cvetaen systems. Vice Admiral Dodd Rancit also theorized that the Imperial facility on the Expansion Region world of Cartao would be the next target of Berch Teller's rebel cell.
