But those Dark Games unleashed a war that threatened to destroy the universe ... until a brave and powerful alicorn warrior caught the magic, locking it in the mystical Elements of Harmony, and sending them to another dimension.

Now, 5,000 years later, a girl named Twilight Sparkle has revealed the secret of the Element of Magic and ancient magical forces have invaded it. Since the fate has chosen her to defend the universe from the Dark Games, just as the brave warrior did 5,000 years ago.
