Swallow Nebula
From Bravo Fleet
The Swallow Nebula is a large Mutara-class nebula approximately half-way through Voyagers path through the Delta Quadrant. It is bordered by a number of mid-level powers, including the Alsuran Empire, the Krenim Imperium, the B'Omar Sovereignty, and the Hirogen, and it borders The Void, which separates it from the Gradin Belt by 2,500 light-years.
Voyager was largely unable to establish diplomatic relations with the powers in this area of space.
