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.

Deep beneath the oceans of Ghyran, in kingdoms forgotten by gods and time and overlooked by the ravages of Chaos, the Idoneth Deepkin endure in bitter solitude. However, the Jade Throne of Briomdar sits empty, its long isolation threatened as never before in its history. The Everqueen’s warsong awakens the forests of both land and sea, and everywhere the diseased knights of Nurgle fight to the last foetid breath for the verdant Realm they claim as theirs. But for Prince Lurien this time of peril is one ripe with opportunity.

Gotrek Gurnisson is the greatest Slayer of the age. He is a relic of a dead world, a sworn enemy of Chaos and a stranger in the Mortal Realms. Now, reborn and hungry for vengeance, he crosses the war-torn lands of Chamon armed with new oaths, pitting himself against the forces of evil. Accompanied by the aelven assassin Maleneth Witchblade, Gotrek marches to war with the Fyreslayers of the Grymm Peak Mountains, with a newfound sense of purpose. The fire in the Slayer's soul has not gone unnoticed, however. Far beneath the sea, the Idoneth Deepkin are stirring.

Far above the highest mountain peaks, a new power has arisen. The duardin have developed new technology and weapons of war, and now they sail the skies in their amazing airships, seeking wealth and plunder. Brokrin Ullissonn, Captain of the Ang Drak, has a reputation for bad luck. Unless his fortune turns, and soon, he will lose his ship and his livelihood. When he and his crew discover the location of a source of aether-gold of unparalleled quality, the temptation is too strong to resist. No matter what dangers present themselves, the duardin desire wealth beyond all.

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.
