The Search For Beechlilly  

This quest is given by Birchbark Oakleaf after you complete Little Lost Landing.

You must gather from a pile of leaves near Spirit Lake until you find five leaves. These are random spawns near -15, -4, -30 Copy and may not be visible until you are very close to them, depending on your graphics settings (but are targetable).

After completing this task you should return to Birchbark Oakleaf for your reward, and to open up The Root of the Problem quest.
