Rafal had lived to complete his oath and rule as the One (the one true School Master), and Rhian, reduced to mortal, was redeemed. Now, both brothers come to terms with their tale's ending, an uncertain, prophecy-less future, and the two begin anew since the Great War, without the constraints of a fairy tale.
And, even Rafal must learn to accept his true nature, his supposed, newly-surfaced Goodness and the guilt it carries.
Additional Context: The "anticlimax" of Fall was narrowly subverted, and both brothers are alive, contending with the aftermath of the Great War.
