A little galaxy. Mostly housing big planets with powerful forces in it. They are very strict with who can enter their territories, so when doing so it is best to bring a heavily armored ship.
The biggest galaxy in the universe. Houses a lot of planets with wide varieties of wild animals rather than humanoids, and is often a good place to stop on long trips where food is needed.
A peaceful area of the universe. This part of it is not very populated, nearly completely abandoned. Many of the planets were the birthplace of powerful races, which moved to bigger planets later in history. A prime example is the changelings.
