Twilight's fears over becoming a princess convince her to attempt a spell to glimpse the future. Unfortunately, she ends up doing a bit more than glimpsing; the spell turned out to be permanent, meaning she never returned back to her own time, and therefore didn't exist for ten full years.

Her absence caused a fall-apart of the elements of harmony, and Twilight is horrified to see how they've changed without her. She doesn't know how to teleport back, so she instead tries desperately to figure out what happened and piece everyone's lives back together.

Several weeks after recovering her crown from Sunset Shimmer, Twilight Sparkle discovers she can communicate with her counterpart from the other world, who has finally arrived at Canterlot High. When Celestia theorizes that the portal can be re-opened, Twilight and her friends--as well as the OTHER Twilight and HER friends--decide to trade places, so they can learn more about each others' worlds. The only catch: neither party can return to their own world for a full thirty moons...

This story is now cancelled. Its concepts will (eventually) be retooled into (Mis)taken Identity.
