Maerdocian sector The Maerdocian sector was a sector in the Mid Rim , within the galactic region known as the Slice and west of Hutt Space . Its Rimward side was traversed by the Gamor Run hyperlane , while the sector ' s coreward boundary marked the end of the Expansion Region . The proximity of Hutt Space made the area a contested territory between the Galactic Republic , which had swollen to include the sector by c . 5000 BBY , and the Hutts , who eventually annexed parts of it by the years preceding the Invasion of Naboo , only to lose it during the Imperial Period . Following the rise of the Galactic Empire in 19 BBY , the Chroma Zed system became a source of slave labor . In 4 ABY , Nagai and Tof forces moved across the sector towards Zeltros in the Inner Rim . The same year , the New Republic advanced in a similar manner towards Kashyyyk from Bothawui . The Maerdocian then experienced a period of peace until the Yuuzhan Vong War , which saw the Deneba system fall to the extra - galactic invaders in the first year of the conflict . Eventually , the sector fell under the sway of Darth Krayt ' s Galactic Empire by 137 ABY . Description . The Maerdocian sector was located in the Mid Rim portion of the Slice , a region that spanned most of the space between the Rimma Trade Route and the Corellian Run . Its coreward boundary was the Expansion Region itself , with the other neighbors being — clockwise — the Eclorar , Daalang , Aida , Noolian and Fei Hu sectors . The Gamor Run , a hyperlane between the Corellian Run and Daalang , traversed the sector near its rimward side , with at least four systems being situated on it . Out of these , the polluted , swampy planet Shador in the Shador system was home to a notable shadowport . Other planets in the sector included Chokan , Chroma Zed and Deneba . History . The year 20 , 000 BBY marked the beginning of the Great Manifest Period . During this time and the subsequent Indecta Era , the settlement of the Trailing Sectors began , while a vast portion of the Slice between the Rimma Trade Route and the Corellian Run was explored , including the territory of the future Maerdocian sector . Parts of the tract of space containing the sector were under Galactic Republic government by the onset of the Great Hyperspace War in c . 5000 BBY , while the rest of the sector became part of the civilized galaxy by 4000 BBY . The Republic managed to preserve its control over the area until the Draggulch Period , when large portions of the Rim were abandoned to slow Sith advance . In 32 BBY , following an unsuccessful meeting on Eriadu and the assassination of four of its leaders , the Trade Federation began its military buildup in earnest , with war matériel from Colla IV and Charros IV being moved to Enarc through the sector . By this time , Hutt Space had expanded as far as to include Gyndine in the Expansion Region , annexing most of the sector . Sometime prior to 27 BBY , Tarshan Ring Excavations , a mining company operating in the Tarshan system in the sector , approached the cloners of Kamino to produce cloned Humans as miners . By 22 BBY and the start of the Clone Wars , the Hutt " bulge " in the eastern Mid Rim and Expansion Region became contested space . The newly formed Confederacy of Independent Systems sought to take the territory north of the Nanth ' ri Route , while the Galactic Republic attempted to reassert its influence over the southern part , which included the sector . After the Galactic Empire emerged , it committed several atrocities on worlds such as Mon Calamari and New Plympto . The world of Chroma Zed in the Chroma Zed system in the northwestern Maerdocian sector also became a source of slave labor . A number of extra - galactic factions launched attacks on the galaxy in 4 ABY , following the crippling of the Empire at Endor . The Nagai and their Tof pursuers — two species hailing from Companion Besh — broke into the Rim territories at the intersection of the Hydian Way and the Corellian Trade Spine . A secondary force of the two alien species advanced north , then turned east , racing across the Expansion Region and the Mid Rim and going through the Maerdocian sector before reaching Zeltros in the Inner Rim . The sector was spared of conflict for the next eleven years . In 25 ABY , the Yuuzhan Vong , a warrior race from another galaxy , invaded known space at a location called Vector Prime , where their worldships were able to break the galactic barrier . During their advance , they attacked Mid Rim systems from the north , eventually capturing the Deneba system in the Maerdocian sector by c . 27 ABY . However , they surrendered a year later , when the galactic capital world of Coruscant was recaptured by Galactic Alliance forces and riddled of vongforming . By 137 ABY , the sector fell under the authority of Darth Krayt ' s Galactic Empire . Behind the scenes . The Maerdocian sector was mentioned several times in the appendix of " The Essential Atlas " . Eventually , " " established its location with Modi ' s map of the sectors of the Mid Rim .
