Reward: Troll's Eyeball
Go and talk to Joseph in the Rookridge Inn, there has been some unexplained pollution driving away all of his customers. He'll need you to investigate it for him. Follow the trail down the same path you once chased Dash, you will meet up with a handful of Bandits, but they shouldn't be too hard to defeat. To your left there is a Wellspring.
Now I don't know about you, but I'm getting mighty sick of Trolls being around everywhere. Nontheless, kill the Troll that creeps up out of the water. In case you didn't already notice, there is also a chest n the room where you killed the Troll. Now go back and meet Joseph to recieve your reward, and a discount to purchase the Inn if you'd like.
