Following Chrysalis's scheme to capture every important pony in Equestria and replace them with Changelings, Celestia came to the conclusion that it was time for some new heroes to arise. Some who would take up the mantle whenever the Main Six or Starlight Glimmer and her friends were unable to assist.

She sends Twilight Sparkle and her friends across the ocean to make some new friends, some who would hopefully be able to fight against the forces of darkness and save the world from any new threats that might surface.

Little do they know that it's not going to be as easy as they think...
