The arm of Orion, the arm of Perseus, and the arm of Sagittarius extend here. The greater half of the United Federation of Planets is located here. Near the planet Bajor is the mouth of the wormhole, which connects it with the Idran sector in the Gamma Quadrant.
Powers: The United Federation of Planets has a dominant position, but much of the quadrant (especially at the Gamma Quadrant) is unexplored. Influential races include the Cardassians, Ferengi, Breen, Trills, Tholians, and more.
