The Unyielding are mostly ghosts of former Alliance Expedition soldiers haunting the ruins of the Expedition Armory in the southern part Hellfire Peninsula. Near the end of the invasion of Draenor, the Armory fell under attack by the Horde's insidious death knights. Those vile shades cursed the Armory's defenders and trapped their souls between the realms of the living and the dead.
The Unyielding have kept writing their history, even after they had fallen in battle.
