Forge world Metalica is the furnace heart of war production in the Charadon Sector. Upon the orders of Abaddon the Despoiler, Typhus leads a vast invasion into the Charadon heartlands, seeking to besiege Metalica and infect it with Nurgle's plagues. Beneath his foetid banner fight not only the forces of the Death Guard, but also warbands from the Black Legion, Word Bearers, Alpha Legion, and countless others. Alongside them come twisted Chaos Knights, endless tides of mutants, cultists, daemons, and even the towering abominations of the Legio Morbidus. Yet against this invading horde stands an Imperial alliance between the armies of the Adeptus Mechanicus, the Adeptus Astartes, the Astra Militarum, and many more. Fighting to dominate the systems of the Lirac and Obolis Sub-sectors, these mighty forces unleash their deadliest weapons in a war that threatens to annihilate the very worlds over which they fight.
