Unknown Regions

The Unknown Regions, Unknown Space, Unknown Sector, or Unknown Territories was the collective term for all regions of the galaxy not formally charted; it differed from Wild Space in that Wild Space was usually minimally charted, but not fully explored.

The Unknown Regions could be broadly defined as areas not connected with the skein of reliable or well-known hyperspace routes spanning the galaxy, did not look to Coruscant as the ultimate center of civilization, or were not under the broad hegemony of the Galactic Republic before the Galactic Civil War&mdash;but the full reasons behind this lack of contact remain unknown.

Location, extent, and relations with galactic civilization
The reach of civilization extended at least nominally to the edge of the Galactic disk&mdash;for instance, the territory of the Corporate Sector extended to the end of the Tingel Arm. The galactic disk and some satellite galaxies were mapped well enough that the omission of 37 systems (including Kamino) from stellar charts were obvious gravitational anomalies, even when scanning from afar. 15% of the galaxy's volume was contained within the Unknown Regions.

The Unknown Regions approached nearest to the galactic disk behind Bakura, Bilbringi, and the Imperial Remnant. Important powers in this area of space included the Chiss Ascendancy, the Ssi-Ruuvi Imperium, the Vagaari, the Venen Empire, the Killik Colony, and the Empire of the Hand, but it was also home to species such as the Croke, the Ebruchi, the Nagai, the Tofs, and the Eickarie.

One hypothesis by a noted scientist suggested that a mass of dark matter intersected the galaxy in this region, creating gravitational anomalies that hindered navigation. However, the lack of any tidal disruption of the galaxy's spiral form (as shown in Jedi Archives) may disprove this supposed dark mass. It is clear, moreover, that much of the Unknown Regions were passable to determined travelers&mdash;for instance, Corellian traders had been in contact with the Chiss for many years before their "discovery."

The large galactic volume designated as the "Unknown Regions" included uncharted areas in dense nebulae, globular clusters, and the galactic halo.

Due to the very fact that the region is "unknown," it presumably has not been charted and divided into sectors.
