Not sure if this was a bug but:
I found him, I had several mobs on me but they were green so I was OK. He was walking and i tried haililng him but he did not respond. I handed him the ring, trade window open.
AS SOON AS I DID HE DISSAPPEARED AND REAVER SPAWNED...but faelin's ring was still in my inventory and NO coin. I did not complete the trade, he despawned before I could even click the trade button. Was this just bad luck? Or a bug?
Now i'm waiting for him to show up again...could take awhile. What could have been an easy hand in has now turned into another long camp.
