Side quests in Madhmr Bridge
You can receive this quest after you meet with Peregund (M15,1). Head out to find the shipwreck in the southern part of the map (M15,4). Along your path, deal with several looters. After you get there, talk to Hanwen and listen to his side of the story. You can either attack Hanwen and the rest of the shipwrecked who are not going to pose a threat to you (negative reputation in Defiance Bay) or go with the peaceful solution and agree to lie to Peregund (lots of positive reputation in Defiance Bay). In both cases, you obtain a valuable headgear (Hanwen either gives it to you, or you find it on his corpse).
