Skavor is an Ancestor God of the Dwarfs. In Dwarf mythology he turned against his people and became the father of the Skaven. He may be the same individual the Skaven known as "The Shaper."[1a]
According to Dwarf myth, Skavor was the son of Gazul, the Ancestor God that protects the Dwarfen dead, and cousin to Grimnir. Skavor was one of the younger Ancestor Gods and showed no aptitude for working stone or shaping metal. He was rightly exiled for this, so he went away into the deep-earth and learnt how to shape flesh instead of metal, turning himself into a hideous rat-beast and swearing revenge on his blood-kin.[1a]
The legend of Skavor is part of the reason the Dwarfs hate the Skaven as much as they do. While the Greenskins have done far more damage to the realms of the Dwarfs as a whole, many among the Dawi believe the Skaven came from their blood, so they fight them to eliminate an ancient shame.[1a]
