Go to Shadowfang Keep and obtain the Silverlaine Family Sword from Baron Silverlaine, 5 crates of Moonsteel Ingots, and 5 Deathless Sinew.
From your earliest days, your trainers always knew you would make your mark on the Horde. You have fought bravely and given our enemies reason to fear.
As a reward for your dedication, the warchief has commissioned his personal smith to forge a special weapon.
The cursed Shadowfang Keep in Silverpine Forest is the only place to get the materials you'll need. Travel there and find the lost Silverlaine family sword, 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?
Grezz Ragefist told me to expect you. Those materials will make a fine sword. Always use it for the glory of the Horde.
