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, situated in the Golgenna Reach, 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.
