O peru and the Swan Queen

"We all know the story.
Virgin girl, pure and sweet, trapped in the body of a swan.
She desires freedom, but only true love can break the spell.
Her wish is nearly granted in the form of a prince.
But before he can declare his love, the lustful twin, the Black Swan, tricks and seduces him.
Devastated, the White Swan leaps off a cliff, killing herself, and in death finds freedom."
