Received from: Wynne [Campsite]
Description: Once you've sufficiently developed your relationship with Wynne the woman will tell you a story of her first apprentice Aneirin. You can offer to find out what's happened to him and in order to make that happen you must travel to [Brecilian forest - Dalish camp]. Talk to Sarel who can be found sitting next to the fire (M41, 8). The elf will inform you that Aneirin is still alive and that he likes to spend his time in the woods.
In order to locate Aneirin you'll have to go to [Brecilian forest - Eastern part] and it's going to be a small camp (M43, 5) located near the place where you've encountered mad Hermit. Naturally you should have Wynne in your team, so that she'll have a chance to talk to her apprentice. Once the conversation has ended you'll receive Aneirin's necklace and you'll finish this quest.
