Proof of Demise: Ley-Guardian Eregos

The Nexus War rages on and we must do something to turn the tide! Are you willing to fly into the heart of the battle, <name>? Ley-Guardian Eregos is the protector of the conduit through which Malygos is funneling the magical power of Azeroth's ley lines. If he can be slain it will be a great blow to the enemy. Please bring me one of his ley line tuners so that we might study it.
