Unknown Regions

"I left for the Unknown Regions, determined to lose myself. I learned that unknown was not the same as empty."

―Darth Krayt to Cade Skywalker[src]

The Unknown Regions, Unknown Space, Unknown Sector, or Unknown Territorieswas 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 was broadly defined as areas not connected with the skein of reliable or well-known hyperspace routes spanning the galaxy, did not belong to the wider well-known Galactic community, did not look to Coruscant as the ultimate center of civilization, or were not under the broad hegemony of the Galactic Republic before theGalactic Civil War. Beyond the region’s outer edge lay the hyperspace disturbance beyond the edge of the galaxy.

"There are a hundred different threats out there that would freeze your blood if you knew about them."

―Stent to Mara Jade[src]

The reach of civilization extended at least nominally to the edge of the galactic disk—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 thirty-seven systems (including Kamino) from stellar charts were obvious gravitational anomalies, even when scanning from afar.

The large galactic volume designated as the "Unknown Regions" included uncharted areas in dense nebulae, globular clusters, and the galactic halos. 24% of the galaxy's stellar mass was estimated to be contained within the Unknown Regions. Many governments repeatedly sent scouts into the Unknown Regions. General Wedge getans once remarked that "If you continue to map the Unknown Regions, you'll have to call them something else." During the early years of the Galactic Empire, a colonization corporation, Anawa, offered refuge to people by guiding them into the Unknown Regions where the corporation would administrate and police newly discovered habitable planets.

The Unknown Regions included a unique section of the galactic disk to the "galactic west" of Bakura, Bilbringi, and theImperial Remnant. A web of hyperspace anomalies in this section known as "the tangle"[4] impeded galactic exploration by the Republic for millennia. 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 and the Eickarie. Though severely cut off from the rest of the galaxy, these species interacted with one another, and had created a sort of interstellar culture separate of that of the Galactic Republic or the Empire. Communication and trade were sparse and infrequent, but species such as the Lugubraa were found in the services of larger powers across the Regions. Common threats such as Mnggal-Mnggal brought together disparate species such as the Chiss, Lugubraa, and others to combat its encroachments.

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 have disproved this supposed dark mass. Alternate theories included "hyperspatial gravitic ripples", or the intentional construction of a barrier, by the Celestials to hedge the expanding Infinite Empire or to contain Mnggal-Mnggal. What was known for certain is that the division between explored space and the Regions was almost precisely at the midline of the hyperspace disturbance that surrounded the galaxy. It was clear, moreover, that much of the Unknown Regions were passable to determined travelers—for instance, Corellian traders had been in contact with the Chiss for many years before their "re-discovery", the planet TX-frezrton (Ilum) was reachable by Force-sensitive navigators, the Rakata homeworld of Lehon was also reached by a Republic naval task force at the climax of the Jedi Civil War and subsequently made a protected historical site by the Republic. Additionally, frontier spaceport worlds in the known galaxy, like Terminus 472389-A, were known to be visited frequently by transports and traders from the Unknown Regions.

In some eras, like during the Great Galactic War, Cold War and Galactic War, prominent species like the Chiss cooperated with galactic powers like the Sith Empire.[7] The Ascendancy also participated in diplomatic talks with the Republic[8] and later maintained relations with both the Galactic Empire,[4] the New Republic, the Galactic Federation of Free Alliances[9] and the second Galactic Empire ruled by Darth Krayt.[10] As part of the relations with the First Galactic Empire, the Chiss Imperial Grand Admiral Thrawn, a native of these parts, was dispatched aboard the Imperial-class 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 Galactic Empire. While there, Thrawn appeared to have encountered the extragalactic Yuuzhan Vong. He also created a shadow Empire, the Empire of the Hand. Normalized relations between the Chiss Ascendancy and the New Republic were established following the Galactic Civil War, and the portion of the Unknown Regions existing in the galactic disk was essentially eliminated thanks to the availability of Chiss star-charts.[2]

Political divisionsEdit

Taungs migrated from Coruscant to the Unknown Regions.

"You remember the devastation of the Yevethan Great Purge? There were things in the Unknown Regions that would have made it look insignificant, save we were there and stopped them."

SectorsEdit

Due to the very fact that the region was "unknown," it presumably had not been charted and divided into sectors by the Republic. However, the Empire of the Hand had plotted 250,000 sectors in the region.
