The Calixis Sector is an Imperial sector in Segmentum Obscurus near the Halo Stars and the Eye of Terror. Conquered by Lord Militant Angevin a thousand years ago, the Calixis Sector contains many heavily populated and important worlds, though it lies a great distance from the Imperium’s heartland. Its first governor was Drusus, one of Angevin’s most capable generals, a man now revered as an Imperial Saint.
To trailing, the Calixis Sector is bordered by the hazardous territories of the Fydae Great Cloud and to spinward by the Scarus Sector. Bordering to coreward, its nearest neighbour is the Ixaniad Sector. To rimward lay the contested and unregulated frontiers of the Koronus Expanse and the Halo Stars.
