Go to Shadowfang Keep and obtain Silverlaine's Enchanted Crystal from Baron Silverlaine, 5 bundles of Moontouched Wood, and 5 Ghostly Essence.
You have proven yourself a brilliant student and a dedicated servant of the Alliance. Word of your accomplishments has even reached the ears of the king.
In recognition of your service, King Wrynn has commissioned the royal enchanter to create a special weapon.
The materials required for your staff are found only in Silverpine Forest's cursed Shadowfang Keep. Travel there and find a lost heirloom of the Silverlaine family, a supply moontouched wood, and the essence of the ghosts haunting the keep.
Did you bring the materials I'll need for your weapon?
Ah, I have been expecting you, <name>. Maginor Dumas has spoken highly of you and the royal commission only confirms his words. It is an honor to be able to craft a staff for you.
