The Skaven are a race of man-sized humanoid rats. They exist in a clan based, underground society so secret from the world that few people believe they exist. Skaven are, putting it politely, conniving, selfish, cruely, cowardly backstabbers. Their clans are so disparate that their war weapons span the gamut from genetically engineered monsters, to specially designed diseases and plagues, to the fusion of magic and science to create supernatural guns, to incredibly disciplined and effective assassins. Should the Skaven overcome their natural inclination towards paranoia and mistrust, they would surely be a powerful adversary in battle.
