Gregora sector

Gregora sector is medium sized and extremely unstable sector of the Imperium of Man. During its long years of existence, it has suffered from major chaos incursions, sector-wide rebellions, revolts and constant warzones on almost all of its planets. Because of this, the sector's population is frequently drawn into service of the Imperial Guard and Navy and many renowned regiments come from the polluted industrial worlds of the sector.

Located in the Ultima Segmentum, south-east from the Galactic Core, Gregora sector is thought to be of little use or significance yet the Imperium refuses to let go of it and has poured billions of men into the warmachines that have grinded in the sector. Lates major war was the 15th Gregoran Reformation in mid-M41 when the rebels were finally put down by the Imperial Guard and most of its planets put under military junta.

Sub-sectors and Worlds
After the 15th Gregoran Reformation, sector was divided into its four sub-sectors that were created after the 3rd Gregoran Reformation. These four sub-sectors span horizontally from northern to southern border and are equally sized. However, they are equal in size only and the actual value of sub-sectors is situated on the eastern side of the sector, leaving the western side somewhat poor and unimportant.

A01-12
Colloqually known as the "Queens", Gregora-A01-12 is the first and foremost of the sub-sectors, consists of twelve planets of which all are of great value to the Imperium and sector alike. Their industrious output is rivalled only by the great forges of the Adeptus Mechanicus. Sub-sector's capital acts as the sector's capital too.
