Dregmar Runebrand yells: I know why you've come - one of those foolish Magnataur on the plains meddled and managed to get the dragons involved. Do you enjoy serving them like a dog?
Dregmar Runebrand yells: You seek their leader... little thing, you wage war against the clans of Grom'thar the Thunderbringer himself. Don't be so eager to rush to your death.
Dregmar Runebrand yells: Hah! So be it. Blow the horn of a magnataur leader at the ring of torches south of the Blue Dragonshrine. Make peace with your gods... Grom'thar will come.
