No land is safe from the threat of the vile ratmen, the Skaven. With a diabolical cunning, the Skaven have a webway of tunnels throughout the entire Warhammer World, from underneath the mountain strongholds of the Dwarfs to the sewer systems of the Empire and Bretonnia's greatest cities. There, black clad Assassins, rabid Plague Monks, and the seething hordes of Skaven watch and wait for the time to unleash their plans for the final apocalypse.
