The mad research of Clan Moulder has resulted in the Rat Ogre - a masterpiece of the mutating effects of warpstone, a magical substance found underground. Only the strongest Rat Ogres survive the horrible conditions their Packmasters impose upon them from birth, forcing them to compete for food and shelter. Those who survive to maturity grow to a height four times the size of a man, and are little more than a mass of sinewy muscles and razor-sharp claws.
Packmasters goad packs of Clan Moulder war beasts into the ranks of the enemy. The Packmasters’ intelligence, coupled with their creatures’ ferocity, is an extremely dangerous combination on the battlefield.
