When Prince Arthas became the Lich king, his mind held sway over the corrupted creatures and peoples of Azeroth. But during a moment of weakness, one of these individuals freed herself from the mind of the Lich King. The Elf Sylvanas then used her will to break the chains that bound many of the corrupted to Arthas' will. These freed souls became the Forsaken, forever in debt to the Dark Lady's gift. This film tells of their birth.
