Diablo - Legends of the Barbarian - Bul-Kathos

"Long before Bul-Kathos became known as the father of barbarians, he was father to only two: his twin children Naarah and Hiram. Naarah followed her father's path and became a great fighter, but the ways of their tribe never came naturally to Hiram. After years on walkabout, Hiram returns to his family, having discovered a new way . . . and a new power he seeks to claim with his father's help."--
