When the Chaos-vermin Skaven rise from their endless burrows, there's always a vile purpose in mind. So when a vast horde equipped with unfathomable weaponry sweep into a backwater of the Empire, disgraced Greatsword leader Frohlich knows there has to be a reason. But can he find out what it is before the thin shield of human steel shatters beneath an irresistible hail of warpstone bullets? Features two alternate covers, both by Karl Richardson.
