[29] The Doomed Fleet:

Go to Menethil Harbor in the Wetlands, and speak with Glorin Steelbrow.

Bishop Farthing: Years ago, the Third Fleet of Kul'Tiras sunk along the coasts of The Wetlands, an expanse of marsh north of the Dwarven kingdom of Ironforge. Aboard one ship was a load of Lightforge Iron.nnThis metal is precious to us, for items crafted from it strike with holy truth. If you are to face Morbent Fel, then you will need such a weapon.nnGo to Menethil Harbor and speak with my dwarven colleague Glorin Steelbrow. If that lost metal can be found, he'll know where to look.

Glorin Steelbrow: Kill 10 Mottled Raptors and 10 Mottled Screechers, Rawlins. My co-workers did not deserve the fate that was brought upon them. It's time to even the score.

Glorin Steelbrow: Lightforge Iron is a precious metal, but it sounds like your quest is a dire one. You've come a long way, Brother. With luck, you might just find what you seek!

And if you do get the iron, I know who can fashion it into a weapon against this Necromancer you speak of in Duskwood.
