I'm the Heroine's Maid

In the kingdom of Verdantire, they lived two half sisters, one who was as kind as a saint, who's golden hair shimmer in the daylight and diamond eyes, she was the favorable one, the beloved. While the other was pushed to the side, lacking, in both magic, and appearance. She was forgettable, she was alone. So I suppose it was not a shock that no one took her side when she was framed to have poisoned her sister. And what's more, the person in question was the beloved sister. She was the one who framed her, she was the one who betrayed her. Someone who was beloved everyone, including her sister, the sister cherished her, and yet she has hurt her to the depth of hell. It was a warm orange day when the lonely sister was executed. And then by miracle or an action of God, she has returned to her child form, from way back the Duke of Marrow has taken her. Yes, that is right, the lonely sister is a main character, and where does that leave me? Well not much really, I am simply a maid of the very Duke that would take the main character in his care.
