You can now leave the cave and take the southern exit from Valewood. Travel to the Gilded Vale and enter Ingroed's Home (M4,4). Start the conversation with Ingroed and Nonton. You can complete this quest either in an amicable or in a hostile way. If you go for the former, allow them to leave the village, either taking their gold or letting them keep it (positive reputation). As for the hostile variant, it takes place once you attack Ingroed and Nonton, or try to report them to the magistrate. It is best to start the fight once you have recruited party members, because the pair is quite strong.
