Seeking to undermine the very fabric of the Empire with their arcane warp-sorcery, the skaven, twisted Chaos rat-men, are at large in the reeking sewers beneath the city. Led by Grey Seer Thanquol, the servants of the Horned Rat are determined to overthrow this bastion of humanity. Against such forces, what possible threat can just two hard-bitten adventurers pose?
