The Azlesa Expanse was a region of space, an interstellar expanse and nebula located in the B'Moth sector of the galaxy's Beta Quadrant. In the 25th century, this expanse was inside the space claimed by the Klingon Empire. (STO - Common Ground mission: "Azlesa Expanse Exploration")
History and specificationsEdit
By 2410, astrography placed the expanse within the borders of the B'Moth sector, and displayed it as a green-yellowish nebula. It was located close to the ChoS Nebula. The region became accessible to Starfleet and the Romulan Republican Force. (STO - A New Accord mission: "Azlesa Expanse Exploration")
The interactions with the region changed further. Ships of the Khitomer Alliance would dispatch duty officers on missions to the expanse, rather than venturing into it directly. The duty officers conducted missions of diplomatic and scientific nature, and assisted with the colonisation of the Azlesa Expanse.
