I switched factions and now my shadowforge key is gone. Also, it won't let me do the quest again. Please return my key. toon is Bulkathos on Arthas server.
Q u o t e: Talk to the locksmith in Dalaran before you put in a ticket.
That would be my recommendation as well. I show that you have completed the quests required for the key so the Locksmith will give you another copy of the key.
