Seek out Chieftain Wintergale at Taunka'le Village.
You have faced all challenges that have been set before you and squashed them beneath your boot heel. It is because of you, [player], that the Horde is now firmly entrenched in Northrend.
But our work has only just begun. We must march to Icecrown and we must tear down its walls!
Your next assignment begins to the east, at Taunka'le Village. Our taunka allies are in dire straits and require aid. Secure transport from the stable master, Durkot Wolfbrother, and seek out Chieftain Wintergale at Taunka'le.
