For centuries beyond counting has the race of malevolent ratmen known as the skaven plagued the Mortal Realms. Arrogant, avaricious and utterly without mercy, the skaven seek to annihilate every other sapient creature – expanding, multiplying, and consuming everything in their path until they alone rule over the decaying husk of reality. Those who defy this vision are overwhelmed by swarms of frenzied, red-eyed warriors, weaponized plagues, monstrous beasts and lightning-spitting war machines. Arise, Children of the Great Horned Rat!
