I figured it was her dad. You know what's strange though is he kind of looked like Finn. I wonder if an under lying plot is they are really brother & sister. As Finn was an orphan if i recall.
As for the map i didn't discover it until i was about 75% of the way through the game LOL
That wouldn`t be a good thing for them to do, (Spoilers Below:
as they are in love and they get together at the end, plus Finn is not a Faerie like Erline and her father.
