It all started with the portal. Twilight had just took out Sunset Shimmer, and was adjusting to life back in Canterlot High. People recognized her as a hero. Principals Luna and Celestia awarded her and the rest of the girls with medals, and Sunset Shimmer was trying to fit in (I mean come on, how would you try to fit in after you destroyed almost half your school and mind controlled the student body?). Anyways, Twilight was doing some research, and found strong signs of mysterious energy and didn't know where it came from or what was causing it. Next thing she knows, she and Sunset were sucked into the portal, and was stuck in an unknown region called Alola.
