Twilight Sparkle, Princess of Friendship, had a vision of a powerful hero, after visiting the human world once more to gather data, she began her work on this said hero, hoping that it would protect Equestria for years to come.

During her tests, Twilight feels she should hide this, though that doesn't last long when a burst of power causes light to flash in Twilights home. How will her friends react to this? Is this truly the hero she envisioned? Only time will tell.
