Durotan

Long before his infant son Thrall is stolen away to grow up ignorant of his own heritage, the young Frostwolf chieftain Durotan begins to suspect that the fel magic warlock Gul'dan is spreading through the orc clans is a corruption rather than a gift — and that resisting it may cost him everything. Christie Golden's novel, a tie-in to the Warcraft film, tells the origin story the movie only had time to gesture at.
