Chapter 1 (Harbor Town)
Tilda, the poor woman sweeping outside Konrad's shop in Harbor Town, has three sons she hasn't heard from. You have to track down all three of them and report back to Tilda with their whereabouts. The three sons are Beppo, William, and Leon and all you have to do is talk to them about their mother, then report back.
Beppo is managing the excavations for the bandits and can be found in their camp, just around the corner from the blacksmith there. William is a recruit with the Monastery, found in the yard during the day (if you have already joined the bandits, you get access to the monastery near the end of chapter 1). Leon is the tricky one, having fled from the city and now resides in an abandoned cabin out in the wilderness. The best point of reference to finding the cabin is to head towards the winding path up to Volcano Keep, and when you meet Stan, continue up to the farms run by Severin. From the farms, align your compass East by South-East and keep going until you reach a pond. The cabin can be seen from this pond. Have a chat with Leon who will also give you a rather extensive quest (see the "Ghost hunter" achievement). After that, track down Tilda again and tell her about her sons in order to become a family man.
