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.
