I got the idea for this picture from the book cover of The Black Swan. Odile is Rothbart the scorcerer's only child and he trained her to be a scorcerer. Rothbbart wants to conquer all woman-kind so he changes all of his women enemies into beautiful but powerless swans. They turn into humans again every night. The only way to break the spell is for the most beautiful swan Princess Odette to fall in love with a prince and for the prince to love her back. She does, the swans go free, and Odile overcomes her father.
