Recently Raene Wolfrunner came through Auberdine from Darnassus and was heading to Ashenvale; she said something about the Furbolgs. I wasn't given an opportunity to ask more about her situation but perhaps you can seek her out and lend her your aid $C. Take the southern road out of Auberdine. Once you reach Ashenvale border continue your path down the road. There you will find Astranaar and Raene Wolfrunner.
Speak with Raene Wolfrunner in Astranaar.
