Ok understood! Idea I had was of a magical being that had been taken beyond the barrier when very very very young to be auctioned off and eventually fell into the hands of someone from Feyborn before they caused a mass turning through exposure. Being raised by the Feyborn before returning back to Pixiewick when old enough (and when the Feyborn was too old to look after them anymore) to live with a friend and eventually to be returned back to any remaining family members they might have after all this time. Creates some plot and also some stories of humans/Feyless interactions that haven't gone as well.
