It has been twelve years since the sisters stepped down and Twilight Sparkle took the throne to rule Equestria. Times have been peaceful, thanks to the power of the Elements of Harmony and their connections to the mane six.

...until those connections inexplicably attach to six young, unassuming ponies enrolled in the school of friendship instead. With these children now controlling some of the most powerful magic in Equestria, the mane six have to scramble to teach them the magic of friendship before anything bad happens that they can't stop.

It won't be easy though. Will these new six be able to harness the power of friendship and uphold harmony while learning about their pasts, or will the mistakes of a bygone era come back to haunt all of Equestria forever?

I dunno. Why don't you read it and find out?
