Step through the flamegate atop the Lightning Ledge in Mount Hyjal, and speak with Jordan Olafson within.
Atop the Lightning Ledge, the Twilight's Hammer has erected an enormous flamegate. I do not know where it leads; I know it is not of this realm, and I cannot enter. None of my other followers have returned.
I need you to enter this realm and be my fangs within. Step through the flamegate. If he is still alive, meet with Jordan Olafson inside. He will give you a token that will allow you to use my powers in that realm.
Be bold, <name>. Find out where that flamegate leads, and destroy whatever lies within.
