The Sixth War Against Chaos

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.

In Their Own Story

The sky above the Black Crater burned with a sickly green hue as Archaon raised his blade. Below him, the dust of a thousand broken armies swirled in the wind. He did not look at the dead; he looked through them to the horizon where the world was ending. The Everchosen felt the whispers of four gods in his mind, a symphony of ruin that drowned out all human thought. Today, the gate would open. Tomorrow, nothing would remain but silence.

Historically, this war follows five previous incursions by the Ruinous Powers, each more devastating than the last. The impact on faction relations was absolute; alliances between Empire, Dwarfs, and Greenskins collapsed under the weight of existential threat. Source material from Black Library novels like 'The End Times' series details the fall of major cities and the corruption of the world. Mechanically, this era introduces the Realmgate system, allowing Chaos to invade multiple regions simultaneously. The war's conclusion signifies the transition to the Age of Sigmar, resetting the board for new conflicts.
