Starswirl was the last unicorn to have studied the magic of other worlds. That was over a millenia ago, and still no one had even thought of using magic in another world. At least, no one until Sunset crossed the portal. Disobeying her teacher, she had taken magic to the new world, and found it altered. After being reformed, she tried to understand the world's native magic, but failed. She found it was different. Perhaps she just needed a focal point, and what better focal point than Equestrian magic?

However, not long after the primary test, Sunset discovers that one of her friend’s pasts has been altered, and all memory of them erased. Only she notices anything is wrong and has enough knowledge of both worlds to save her friends.

Now history requires an Editor, and Sunset will have to step up if she is to save her friends.
