The most prestigious and densely populated planets in the galaxy are in the Core Worlds, the ancient region bordering the Deep Core long governed by the Republic.

The Inner Rim is the section of the galaxy between the Colonies and the Expansion Region. During the growth of the Republic, the Inner Rim was colonized after the Colonies region, and was then known simply as "The Rim". Later, the Expansion Region was opened up to colonization. A sudden boom after this led to the establishment of two more regions, the Mid Rim and Outer Rim, and saw the "Rim" renamed as the Inner Rim.

The enormous area of space between the Inner Rim and outer rim territories has few natural rescources, leaving it less populated and wealthy than its surrounding regions. It is largley unexplored, as exploration is discouraged by the fact that numerous pirates and smugglers have set up bases on uncharted worlds in this region.

The group of star systems that lie on the remote edges of the galaxy. Outer Rim territories is a vast region, strewn with alien homeworlds and rugged frontier planets.

The ragged fringe that seperates galactic civilization from the unknown regions. Wild Space is the true frontier of the galaxy.
