Nearly thirty years in the future, the Mane Six have married and settled down to raise families of their own. When Andromeda, Twilight's daughter, rediscovers a familiar time-traveling spell, she makes it her mission to fix what was once unfixable. The spell goes wrong and she and the other sons and daughters of the Mane Six find themselves in the past (before the events of Twilight's alicorn coronation). Separated after the jump, they must all find each other in time before they are discovered, or else they risk changing history and even erasing their own existence.
