When Celestia and Luna had found The Tree of Harmony and discovered the Elements, they were met with, not 6, but 8 of them. Honesty, Kindness, Generosity, Loyalty, Laughter, Symphony, Memory, and Magic. When the battle between Harmony and Chaos came to an end, Discord had managed to send both Symphony and Memory through time and space before he turned to stone.

These two elements, thought forever lost, had managed to somehow end up in the human world, 2 years before Sunset Shimmer stole the crown. One of them, Memory, was found in the garden of a green-haired girl that nobody could see, while the other, Symphony, was found by a troublesome boy while he was planning for his next prank. These two Elements made a connection with the ones that found them and had ultimately changed their lives forever.

This is the story of how Wallflower Blush and Frenzy Beat will change the course of the history of their world, and it all starts at Canterlot Highschool.
