Battlefleet Calixis officially came into being in 384.M39 when General Drusus declared the Calyx Expanse conquered and the Angevin Crusade at an end. The newly formed Calixis Sector was established with Scintilla as its capital world and Port Wrath selected to act as sector naval headquarters. A substantial portion of the Angevin Crusade fleet dispersed to the coreward sectors, some returning to berths that they had left some sixty standard years before while others journeyed to join Imperial Crusades further along the rim. Aided by several Escort squadrons, the remaining half-dozen ships of the line formed the nucleus of the new Battlefleet Calixis.
