Atrivis sector

Despite being a small sector in the northern Outer Rim Territories, the Atrivis sector and its inhabitants participated in several events of historic significance. From the hosting of a Rakatan outpost of the Infinite Empire in 30,000 BBY; to giving birth to the formidable Death Star in 0 BBY; to forming part of the most stable Imperial splinter faction, the Pentastar Alignment, between 6 and 11 ABY; to supporting the splinter Empire-in-exile in 137 ABY; the Atrivis sector was involved in tumultuous events. Located in the New Territories, the sector was traversed by the Braxant and Relgim Run hyperlanes, and was home to several native sentient species, including the Ho'Din, Makurth, Shaliz'Na and Zeffliffl. These civilizations and the immigrants that joined them there were united by their fierce independence. Full exploration of the sector began in 15,000 BBY and continued through until 1,000 BBY. During this period, Ho'Din participated in the Great Hyperspace and Mandalorian Wars, while Makurth participated in the New Sith Wars.

During the Clone Wars, the independent attitude of the Atrivis sector's inhabitants manifested in sympathy for the Confederacy of Independent Systems. The Confederacy employed the notorious Pirates of Iridium to raid supply lines, and ran a research factory on Fest, but was eventually defeated by the Galactic Republic. Later, the rise of the Galactic Empire saw the sector placed under the control of Grand Moff Tarkin as part of Oversector Outer. The sector was home to some of the earliest resistance to the new autocratic government, although its inhabitants remained internally divided in their resistance efforts until the massacre of Mantooine led to the establishment of the unified Atrivis Resistance Group.

For two years, the Empire constructed the Death Star in the sector's Horuz system, supporting the battle station's construction with labor from penal institutions on Gree Baaker, Desolation Station, and Despayre. The Death Star repelled several assaults by the Alliance to Restore the Republic before using its superlaser to shatter Despayre, subsequently leaving the sector on a quest to eliminate the Alliance leadership and cow the galaxy into submission. Conflict, however, continued in the sector with altercations at Atrivis, Fest and Spefik, and as part of Operation Cobolt.

Following the death of Emperor Palpatine at the Battle of Endor, the Atrivis sector was included within the newly-formed Pentastar Alignment, an Imperial splinter faction led by the calculating Grand Moff Ardus Kaine. The Alignment lent forces to Grand Admiral Thrawn, who personally planned an assault against Generis that transpired only eight days prior to the assassination of the Grand Admiral. The death of Kaine during Operation Shadow Hand the following year precipitated the eventual transition of the sector into New Republic control. It remained in Republic hands for only a few, short, years before it was conquered by the invading Yuuzhan Vong in 26 ABY. Following their eventual defeat in 29 ABY, the Atrivis sector soon passed back into Imperial territory as part of a newly resurgent Empire. It would remain under Imperial control until after the Sith–Imperial War, when it began to support the Empire-in-exile of deposed Emperor Roan Fel.
