Bajor sector

From Memory Alpha, the free Star Trek reference.

The Bajor sector, or Bajoran sector, is a sector in the Alpha Quadrant containing the Bajor system, the Federation space station Deep Space 9 and Starfleet's Antares Ship Yards.

In the mirror universe, Terok Nor was the center of authority for the sector. (DS9: "Crossover")

In an alternate timeline Starfleet had to leave Deep Space 9 and the Bajoran sector. The Klingon Empire took over the control of the sector. (DS9: "The Visitor")

The Klingon Empire attempted to place a minefield around the sector in 2372, but their plan was stopped after Worf and Kurn obtained the detonation codes. (DS9: "Sons of Mogh")

In 2375, while he was posing as Wendell Greer, Luther Sloan told Julian Bashir he had many questions about the sector, such as its navigational anomalies and transport patterns. (DS9: "Inter Arma Enim Silent Leges")
