|Age of Myth | Age of Chaos | Age of Sigmar|
This period lasted for many hundreds of years where the Gods of Chaos ruled over seven of the Eight Realms. Fortresses and strongholds dot the landscape of the world, erected to watch over the subjugated races and eased the passage of Chaos into the mortal realms. All who stood against Chaos was killed, empires were overthrown and rulers deposed. Only those who followed or gave in to the power of Chaos survived free, the rest were either killed or enslaved. No opposition was capable of being raised against them in sufficient power and the dark gods revelled in their success.
The forces of chaos are, by their nature, fractured. They can however temporarily unite in order to fight for a common goal. This combination resulted in the sacrifice of entire cities in rituals, corpses piled in mountains. Most battles were won by sheer bloodthirsty destruction by both mortal warriors and the Daemon Legions. The land over which the daemons walked turned to a nightmarish vision of the Realm of Chaos itself. It was also corrupted with more and more fell power. The natural inhabitants of the realms mutated into chaotic beasts and monsters, and mutation was rife in the remaining mortal tribes.
The chaos gods gifted successful mortals with unlimited power, or earthly pleasures, or anything that could be dreamt of. Warriors became super-humans, sorcerers could wield their power with just a whispered word. Those who failed however were destroyed.
Meanwhile, Sigmar had retreated to Azyr where he plotted his return to the mortal realms. He had sealed the Gates of Azyr and gazed upon the other realms from his throne. He watched tribes struggle under oppression, monsters preying upon mankind, Orruks swept across realms and Ratmen burrowed through the ruins left behind. The Skaven also were able to tear holes in the fabric of time itself. Nagash and the undead stood against Chaos but was defeated.
The was one hope however. Sigmar could see in the souls of the now feral humans, who fought for freedom, a spirit to equal the savagery of their enemies. Ultimately however, even an army of these forces would fall against Chaos. Sigmar called upon the allies he had made during the Age of Myth and, willingly or not, they gifted him something which would allow Sigmar to craft a force of warriors to defeat Chaos. Often in the midst of a mighty battle or last stand, human warriors would disappear in bolts of lightning. They were transported to the the Celestial Realm where their trials began to become a Stormcast Eternal. In Sigmaron, new halls, forge, laboratories, armouries and barracks were created to hold and arm the Stormcast Eternals.
Aqshy was the location of the return of Sigmar. His forces appear on the backs of lightning bolts and the rolls of thunder. Instantly, warriors appeared after each thunderstrike and their war cries were heard across the realm. From this point on the Age of Chaos had ended and the Age of Sigmar had begun.
