During the Galactic Civil War, the Rayter sector had a network of subspace relay stations operated by the Rayter Sector Subspace Broadcast Network (RSSBN). It had been authorized by the Rayter Sector High Advisory Council in order to replicate a small part of the Old Republic's HoloNet. It consisted of sixty-four relay space stations and planet-based broadcast centers.
During the Galactic Civil War, the Rayter sector was governed by Moff Nile Owen. The Imperial Sector Fleet included the Imperial-class Star Destroyer the Impending Doom and the Imperial cruiser Kana's Steel. During Operation 45RA, Owen tried to bring the Shashay over to the side of the Empire, but was foiled by Rebel agents.
The Alliance itself had no bases in the sector; it operated from Berrol's Donn in the neighboring Kriz sector. The Worthless Fool, a VR-10 Cuirilla-Rayl Xylines-class Spacetug, was one of its ship available for its operations.
