Over the centuries, the foul ratmen have spread, starting settlements beneath unsuspecting cities and invading underground strongholds from below. They have created a vast web of tunnels across the world.

With their heightened intellect and humanoid bodies, the Skaven have learned to use warpstone to fuel their corrupt sorceries and to create weapons of awesome power. Warpstone is vital to the Skaven — it drives their civilisation.

Skaven rely on weight of numbers and potent magic to overcome their foes. Regiments of Clanrat warriors swarm forward in a squeaking tide supported by the insane warpstone weapons of Clan Skryre and the mutant beasts of Clan Moulder. Clan Eshin ambush the unwary, and the frenzied Plague Monks squeak their devotion to the Horned Rat as they hurtle into the enemy.
