Assassins sent by Garrosh Hellscream attack the troll Vol'jin, the brave leader of the Darkspear tribe, and leave him at death's door. But fate smiles on the wounded warrior: brewmaster Chen Stormstout finds an old friend and transports him to a safe place for treatment - a secluded mountain monastery on the legendary continent of Pandaria. There, gradually recovering, Vol'jin struggles with the old hatreds smoldering between the Alliance and the Horde - side by side with a mysterious man also recovering from injuries. However, Vol'jin's troubles are only just beginning. He soon finds himself drawn into an invasion of Pandaria led by the Zandalari, a legendary tribe of trolls driven by dreams of victory and military might and supported by a legendary, semi-mythical race. They offer Vol'jin a chance to regain the glory that is every troll's birthright. And this offer is twice as tempting after Garrosh’s vile betrayal. The choices Vol'jin makes could save his people... or doom the trolls to languish under the cruel thumb of the Horde leader.
