Twilight Sparkle accidently finds a hidden compartment at the Canterlot Library that reveals a book about a history that predates Equestria that even she hasn't heard of before that makes her want to know if it really happened or if it was just some folklore. Looking through the book not only shows a human known as Megan Williams that once came and was seen as a savior, but also the ponies that the said human was with made her feel as if she was almost looking at herself and her friends in seeing how similar they were both by looks and description. However, she is told that it might have been destiny to not only find that book, but meet the very human mentioned and bring her back with her. Will this former savior accept it or just want to move on with her life especially when knowing that it's no longer the way she remembered when she was last there? This is a crossover between G1 and G4.
