Augustus Malevolyn is a General of an army in Diablo: Legacy of Blood. He seeks to conquer the known world with the help of the Warlord of Blood's armour.
He finds the helmet of the armour, and the helmet gives him power to cast powerful spells. But the armour has a mind of its own, making him do the bidding of the soul of Bartuc.
He is revealed as the descendent of Bartuc himself, and Norrec is a distant relative. He is killed when fighting with Norrec over possession of the armour.
