The XII Legion, sons of Angron the Conqueror, were red-handed monsters long before Horus raised his banner of treachery. None of the Legiones Astartes, not the Night Lords, nor the Space Wolves or the White Scars, were so savage and dreaded; for the World Eaters to be assigned to a campaign meant that the only outcome was extermination. Extermination not by virus bomb, or cyclonic firestorm, but by chainaxe and bolt shell; worlds drowned one-by-one in a storm of butchery.
