Kudos for originality. Although you have all the familiar elements of a dark fairy tale (witch, cave, broken pledge, grudge), you redeem the piece when you have the courage to offer a tragic end. They did not live happily ever after. Even Drizella, who gains her freedom, surely will not be happy. She will not have more children (certainly not with Oak) and she will have an awareness of having imprisoned her daughter.

You write well here (though at one point Oak's name is not capitalized). You don't offer simplistic characters. No one is completely good or bad. Even Afoke, the innocent victim, is flawed, because she is rebellious. Without that flaw she would not have been imprisoned by her mother.

Thank you for sharing this with us, @bipolar95.
