Since I have now learned what the story I’ve been thinking of is (The Wise Woman, or The Lost Princess, by George MacDonald) I thought I’d share with you what hundreds of retellings and the course of time does to a story.
This is what I wrote down Monday when I was supposed to be learning about tiered learning and dissa-something-er-ation, but wasn’t paying attention.

Once upon a time a princess was born and the good witch gave her a mirror to connect her to her people to keep her a fair and kind ruler, it would give her the ability to speak through it to her subjects. But in the night the evil witch came and changed the mirror for while she could not be so powerful she was capable of corrupting something good. The evil witch made the mirror so it could only connect to one person only, a child as well - one the witch knew she could twist to her purposes.
When the princess grew older she started using the mirror and not knowing exactly how it would work did not think it odd that it showed a girl, her complete physical identical twin. They spoke often and became good friends but the witch whispered lies into the peasant girl’s ear about how the princess knew that the mirror was capable of bringing people through but did not care enough about her friend to save her from her wretched life.
The peasant girl grew jealous and hateful and used the princess’s kindness to learn all about her life. And then, the day before the princess was to be crowned heir, the peasant girl pulled the princess through, took her place, and destroyed the mirror. The princess was smart and fared well enough in the wild country even though she did not know where she was. Eventually she found her way to a neighboring country and met a lord who told her how the witch and peasant girl had begun to crumble her country…

And that’s where the story starts breaking down. I think after so many new tellings, it’s just become completely warped.
Thanks for the help!
