The Gatekeeper

“According to these tomes, one of Ragnaros' most powerful lieutenants serves as the sole gatekeeper to Sulfuron Spire. You won't be able to defeat him alone. Sound this horn when you engage in combat with Azralon and any of our forces in the vicinity will come to your aid. You must hurry, adventurer. It won't be long before the Firelord realizes what we're up to.”
