Mission Text:
 * "All this talk of traitors worries me. Although I am loathe to do so, it may be time to turn toâ€¦alternative sources of information. Deep within the forest lives Dark Oak. He does not usually choose to show himself, but perhaps if our need is great he will make his presence known. One of my scouts named Melthoran, who is stationed in the Reed Bog, knows where to find him. We need someone to seek out Dark Oak and obtain his counsel.


 * Will you undertake this task?"

Walkthrough
This is fairly straight forward, you can kill Drogo Greatmane on your way to find Dark Oak, and then simply deliver the heart to Dark Oak to complete the quest. Drogo Greatmane is located in the western portion of the Reed Bog, while Dark Oak is a short distance south-west of the entrance to The Falls.
