The Age of Sigmar began with the thunderous arrival of the Stormcast Eternals, borne upon the heavenly storm of the God-King Sigmar. Great heroes, snatched up at the moment of death and magically reforged, the sought vengeance on the followers of darkness, and the re-taking of the realms from Chaos. Yet in Shyish, the Realm of Death, the dark sorcery of Nagash, Supreme Lord of the Undead aims to transform the Mortal Realms into an ordered empire of mindless thralls. This is a new epoch, a time of mighty battles and unending war. This is the Age of Sigmar!

The Age of Sigmar is an epic setting populated by myriad armies, powerful heroes and magnificent monsters. It plays host to vast, realm-spanning wars between the forces of Order and Chaos, Death and Destruction. In the Warhammer Age of Sigmar Core Book, you'll not only learn the rich history of this war-torn Age, but you'll find all the rules you need in order to evoke these epic stories on the tabletop.

Background

- The Tale of Aeons: this first section of the book contains a detailed, illustrated story-so-far, from the shattering of the world-that-was to the present. This covers 3 major Ages:

- The Age of Chaos, brought about by the machinations of the Chaos Gods and their command of the Realm of Chaos, spitting daemon legions forth and destroying the peace that once reigned;
- The Age of Sigmar, in which vengeance against the Chaos Gods was meted out with celestial fury in the Realmgate Wars, with detailed background on Nagash's dire plan to take back every mortal soul – which he sees as his by right. His necroquake, which has caused every dead being in the Mortal Realms to be reconnected with its essence, has led to wild, untamed magics and undeath taking hold in every realm – and thus the Soul Wars have begun...
