Warhammer Fantasy: Ogre Kingdoms

From the introduction: Long ago, when the Old Ones were trying to create a race that could assist them in their fight against Chaos as the perfect soldiers, the Ogres were created. Strong, sturdy, resistant to Chaos and not too bright, they seemed the perfect warriors. But the Old Ones could not finish the project and were forced to leave the Ogres halfway done. The Ogres minded not, the simple race being happy to live out generations on the wide plains they came to be on, hunting her beasts and competing with each other.
