As the Cataclysm rips through Azeroth, Warchief Garrosh Hellscream orders the best warriors of the Horde to come forward and serve in a new army, lest their foes in the Alliance sense weakness and attack. We meet these warriors as they come forward - from very different lands, backgrounds, traditions. Will they be able to overcome their deep differences and work together to serve the Horde, especially when challenged by a powerful, unfamiliar race claiming to be the real rulers of Azeroth?
