Far from this world and its petty wars exists a dimension of pure malevolent magic: the Realm of Chaos. It is a terrible place, incomprehensible to the mortal mind. It whispers promises of power, but to seize them means succumbing to temptation and losing one's soul. To become a part of it.

As the rulers of this place, the four powers of corruption are just waiting to shed their chains and let the world sink into demonic corruption: Nurgle, the Plague God; Slaanesh, Prince of Excess; Tzeentch, the Changer of Ways; and Khorne, the Blood God and Lord of War.

Two powerful kingdoms stand watch between the worlds: the resilient warriors of Kislev and the Grand Empire of Cathay. Yet both have their own problems—and now a reason to cross the border and send their armies into the Realm of Chaos.

The world stands on the brink. The slightest push could plunge it into cataclysm.

And there is one who wishes to achieve just that. Ancient and with an insatiable desire for all-encompassing power. To reach his goal, he needs a champion…

The coming war will stop at nothing. Will you conquer your demons? Or command them?.
