Into that Vast Expanse
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.
The Hive World of Scintilla is the capital of the Calixis Sector. Along with the hellish Mining World Sepheris Secundus and the war-torn planet Iocanthos, it forms a triumvirate of worlds essential for the sector’s survival. The most powerful man in the Calixis Sector is officially Sector Governor Marius Hax, who rules the sector in the name of the Adeptus Terra from the Lucid Palace on Scintilla. However, the Calixian Conclave, led by Lord Inquisitor Caidin, is the ultimate authority in the sector, a clandestine and all-powerful presence behind the visible emblems and figureheads of power. No one has the power to gainsay the word of the Inquisition.
