Sector Beta, situated within the confines of the space station named Zirtran's Anchor, functioned as a hub. It housed both the central offices for the station's security personnel and a limited Imperial military presence.
The headquarters for Defensus Solar was based in Sector Beta. Their operational center was a corvette from the Old Republic era, linked to the original Zirtran barge. Several other ships, incorporated into the Defensus Solar headquarters, were connected to this corvette. Two antiquated ships, attached to the corvette, were utilized as barracks, and for investigative and forensic work. A converted passenger ship served as a prison for holding detainees.
A compact Imperial Customs facility also occupied Sector Beta. A modest barge acted as the Imperial operational base in Zirtran's Anchor. It featured a small docking area capable of accommodating one squadron of TIE fighters and a pair of Skipray blastboats.
The majority of the commanding officers were largely apathetic, with many nearing retirement and desiring a peaceful conclusion to their Imperial service. They frequently delegated tasks to the Defensus Solar unit, responsible for station security. Younger officers often felt discontented with their assignment on Zirtran's Anchor, yearning for different postings.
Numerous Imperial Army platoons, along with two stormtrooper teams, were stationed on the station, but had minimal responsibilities.
