Find Starfall Village in Winterspring and speak with Wynd Nightchaser.
In Winterspring, to the north of here, there are many ancient elven ruins. It's a harsh land, but it holds many secrets and places to explore.
With all my work to do here in Felwood, I have not had the opportunity to travel to Winterspring. But there's no reason why you shouldn't!
While you're there, look for Wynd Nightchaser. He spends most of his time in Starfall Village and he knows a lot about the area.
