Lore & Background
Unlike previous wars fought for territory or slaves, this conflict was existential. Archaon, united by the will of Khorne, Nurgle, Tzeentch, and Slaanesh, marched to kill Sigmar himself. The war saw the skies torn open by Realmgates, allowing daemonic legions to pour into the mortal plane with unprecedented ferocity. The corruption spread like a plague, turning fertile lands into wastelands and twisting loyal heroes into traitors.
Major powers like the Empire and the Dwarfs found their ancient defenses crumbling under the weight of magical storms and endless hordes. The war was less about strategy and more about survival against an enemy that fed on despair itself. Ultimately, the conflict reached its zenith during the Siege of Karaz-a-Karak, where the fate of the world hung in the balance. The destruction wrought by this war was so absolute that it necessitated a cosmic reset, ending the cycle of the Old World and forcing the gods to reshape reality into the Age of Sigmar.
