Unknown Regions/Legends

The Unknown Regions 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 centre 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.

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 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 travellers&mdash;for instance, Corellian traders had been in contact with the Chiss for many years before their "discovery".

The Chiss Grand Admiral Thrawn, a native of these parts, was dispatched aboard the Imperial Star Destroyer Admonitor to the Unknown Regions during the years of the Galactic Civil War, ostensibly on a simple mapping expedition, but in reality to explore and subjugate entire sectors for the Empire. While there, Thrawn seems to have encountered the Yuuzhan Vong. He also created a shadow Empire, the Empire of the Hand.

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

Behind the scenes
The depiction of the Unknown Regions varies from source to source. Some fans would like to limit the term to areas outside the plane of the galactic disk, and this hypothesis is not contradicted by any canon or EU evidence. It is supported by movie canon, which describes a Galactic Empire, and in which the entire Galaxy can be surveyed for any lost planet, fugitive General Grievous, or Rebel base.

In Vision of the Future, the space known to the Old Republic, Empire, and New Republic is not specifically assigned to any section of the Galactic disk, nor are the Unknown Regions. They do appear adjacent on the map, which includes the disk. The territory under the hegemony of the Empire of the Hand, while by no means comprizing all of the Unknown Region, seemingly embraces as much as 240 sectors, roughly a quarter of the volume of known space. Although huge, this volume is emptier than the Galactic disk, since the combined total of the Unknown Regions contains no more than one percent of the Galaxy's stars(Galaxy Guide 8: Scouts p24; Tales of the Bounty Hunters p301). In contrast, the Essential Chronology and New Jedi Order series, and the associated Galactic Map, have bulked the Unknown Regions on one side of the Galactic disk, and this seems now to be a geometric projection of sub-volumes above the disk. (However, a minority of fans impose a two-dimensional interpretation, in which the Regions actually touch much of the disk.) Worlds such as Kamino, lying "beyond the Outer Rim" on the opposite side of the Galaxy, in a dwarf satellite galaxy 70,000 light years from the Galactic centre, might also be considered as lying on the edge of this zone.
