The Sphere of Civil Administration was one of the five Spheres of Influence of the reconstituted Sith Empire that was created by Empress Darth Acina after the Eternal Empire conquest. The Sphere was the combination of the Spheres of Production and Logistics and Laws and Justice and was led by Dark Council member Darth Vowrawn.
The Sphere of Civil Administration was a power base of the Sith Empire responsible for overseeing supply lines and weapons production, as well as enforcing internal laws. It was established by Empress Acina to lessen the infighting between Dark Council members, and was one of the five seats that succeeded the twelve Spheres of Influence. The Sphere was led by Darth Vowrawn.
If the player character sides with the Galactic Republic during the events that take place on Iokath, subsequently causing Acina's death, Vowrawn would ascend to become the Emperor. In the instance that this occurs, the Sphere of Civil Administration would then be helmed by Darth Shaar.
