Go to Shadowfang Keep and obtain the Springvale's Sharpening Stone from Commander Springvale, 5 crates of Moonsteel Ingots, and 5 Deathless Sinew.
Many members of the Shattered Hand do not survive their training, <name>. Not only have you survived, but you will soon become a feared blade of the Horde.
As a reward for your progress, the warchief has commissioned his personal smith to forge a weapon.
The cursed Shadowfang Keep in Silverpine Forest is the only place to get the materials you'll need. Travel there and recover Commander Springvale's sharpening stone, a supply of moonsteel ingots, and sinew from the ghouls and geists infesting the keep.
Did you bring the materials I'll need for your weapon?
Gordul told me that you would be bringing a variety of unusual materials, but I didn't expect anything like this. Moonsteel is said to be very rare and there's only one place I know to get it. You have risked much for this weapon, <name>, and I'll see to it that you receive a fitting reward.
You will receive:
