The Realm of Beasts has ever been a place of savagery and destruction, defiant in the face of Sigmar's feeble attempts at liberation. But now, deep within the mountains of the Ghurish Heartlands, something ancient stirs. A god long-trapped is about to awaken, and the drumbeat of war calls. Ferocious Ironjawz, gluttonous Ogors and towering gargants all set their sights on the human interlopers, determined to cast down their keeps.

In the north of the world the forces of Chaos gather, awaiting their moment to strike. At their head is the Everchosen, the warrior who will lead the final, cataclysmic assault that will usher in the End Times and the reign of the Ruinous Powers. But he was not always thus – he was once a man, a devout servant of the warrior-god Sigmar. What could cause such a soul to fall to the worship of the Dark Gods? What dark events could have put a knight of the Empire on the path to becoming the harbinger of the world's end? And just who was the man who will become known to all as Archaon?

For generations, the people of the Howling Vale have fought against this madness, largely in vain. Now, Kosomir Vornarov, the city’s Master Patriarch, risks everything – his reputation, friends, even his people’s survival – to destroy the flesh-eater menace entirely and forge a brighter future in his name. Two ambitious lords, two haunted souls. Whose madness will prove the stronger?

In the bleak, haunted underworld of Shyish, a vengeful Slayer seeks the Lord of Undeath. Gotrek Gurnisson returns, his oaths now ashes alongside the world-that-was, his fury undiminished. Branded with the Master Rune of Grimnir, the God that betrayed him, and joined by Maleneth Witchblade, a former Daughter of Khaine turned agent of the Order of Azyr, the hunt has taken them far and wide through the Realm of Death. Will Gotrek find a path to the Undying King or will the underworlds claim him as their own?

For Ianthe, war is all too familiar. A former soldier in the Astra Militarum, she now serves Inquisitor Covenant as an agent of the Throne. Her first mission sees her investigating a cult called the Children of Eternity. Falling foul of the local Enforcers, Ianthe soon learns that war in the shadows is seldom straightforward and that the local, angry law-keepers are the least of her troubles.
