This quest is not available in game.
Bring Coleman Farthing the Agamand Family Axe, the Agamand Family Sword, the Agamand Family Mace and the Agamand Family dagger.
The Agamand family were my employers in life, and they were the cause of my death! It is fitting that the Agamands are now mindless minions of the Lich King.
Now I would have their last vestiges of honor. Go into their family crypt and rob them of their family heirlooms: a sword, an axe, a dagger and a mace. Bring them to me!
The Agamand family crypt is at the north end of the Agamand mills, protected by lurking Scourge and dead Agamands.
