Gryan Stoutmantle wants you to talk to Wiley in Lakeshire.
The band of wretches responsible for driving the good people of Westfall from the land call themselves The Defias Brotherhood. I need you to infiltrate this clan of thugs. We need to know who heads up the cartel and where they are hiding out. In Lakeshire, in the inn, there is a rogue by the name of Wiley who owes me a favor.
Travel to Lakeshire in the Redridge Mountains, east of Elwynn, and find out what you can.
