Description:
Shadows of the Horde follows Vol'jin to the lost continent of Pandaria, where the troll chieftain's loyalties are put to the ultimate test when a member of his own faction moves to assassinate him. . . .
  
Aided by the renowned brewmaster Chen Stormstout, Vol'jin takes refuge in a remote mountain monastery to recover from his wounds. His time there, however, is far from peaceful, as intense visions of the past assault the Darkspear chieftain, and the ancient Zandalari tribe mounts a series of attacks on Pandaria. In his struggle to make sense of what's happening, Vol'jin must ultimately decide where his allegiances lay—a choice that could save or doom his people . . . and forever alter the fate of the Horde.
