You need to be friendly with Honor Hold to start this quest.
Near the end of our invasion, the Armory to the south 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.
Those noble souls must be set free! I beg you, <name>, end my comrades' torment, for I have not the heart to slay them myself.
Upon completion of this quest you will gain:
9800 xp or 2 58 50 at level 70.
+250 Honor Hold faction
The Sons appreciate your efforts, even if few are willing to speak of the armory.
