Find Duskwing and slay him. From the corpse, recover a Patch of Duskwing's Fur and return it to Nathanos Blightcaller. It is said that Duskwing roams the countryside to the north of Marris Stead.
Up until now, you have completed the missions I have assigned; even if not in the most timely manner.
I suppose you think that you are ready for a challenge. Yes... Yes, imbecile, perhaps you are ready for a more involved set of missions.
The albino demon bat, Duskwing, roams the countryside just north of here. Track him down and destroy him. Return to me with a patch of his white fur and you shall be rewarded.
