Often confused with beastmen, the Skaven are no mindless horde of ravaging beasts, but rather a sinister force plotting the downfall of the Empire. Between the manufactured plagues, their Warpstone technology, and the mutated monstrosities that stalk the byways of the Under-Empire, the threat of a Skaven invasion has never been more imminent. Children of the Horned Rat reveals the secret world of the loathsome Ratmen, serving as the essential guide to all things Skaven. The perfect accessory for any game set in the Old World, the Children of the Horned Rat exposes one of the gravest dangers the Empire faces. Don't believe the lies. The Skaven do exist and they will make slaves of us all!
