Speak with Bink in Ironforge.
<name>! Bink, my gnome colleague in Ironforge, sends word. She has a task that needs doing and won't rely on anyone but a mage to do it! Are you that mage, <name>?
If so, then speak with Bink. She spends her time in the Hall of Mysteries in the Mystic Ward of Ironforge.
