Manachean Commonwealth

The Manachean Commonwealth is an aggregate of advanced and populated worlds that lies at the border of both the Segmentum Obscurus and the Ultima Segmentum. Established in the early millennia of the Dark Age of Technology, the Commonwealth is first and foremost constituted by the sprawling Hive-worlds of the Manachea System and the neighbouring Imperial Navy Sector Headquarters and fortress of Port Maw. Since the days of the Great Crusade and its liberation from the baleful rule of the xenos empire known as the Mitu Conglomerate, it is arguably the most strategic vital area of the entire Coronid Deeps. This arguably led the Traitor Warmaster Horus Lupercal to personnally lead the conquest of the Manachea-system after his gambit at Istvaan had failed.
