I get the feeling that this is a prophecy like “the Chosen One will bring balance to the Force”. Magic has its price, wishes never end well, and deals always have a hidden irony clause. I think that breaking the curse will completely sever the characters’ ties to fairy tale land, releasing them fully into our world. Fairy tales are metaphors for growing up; they’re about going forward, not back.
