When the unicorn Sunset Shimmer, in the dead of night in the Crystal Empire, steals the Element of Magic and flees through a mysterious, enchanted mirror, Princess Twilight Sparkle and Spike immediately give chase...and all three are transported through the mirror to a new world, and the realm known as the Halidom of Ylisse.

Through a strange series of events, including meeting the Exalt of Ylisse, Chrom, and his militia, the Shepherds, Sunset, Twilight, and Spike must work together with them in order to find a way back to Equestria. Fate would not have it be so straightforward, as the three will learn that the realms of this world, Ylisse included, have their own dangers to triumph over and tasks to fulfill. Because their new adversary seeks to claim not only the Element of Magic...but the other Elements as well.

It will take a surplus of skill and strategy, powerful magic, and masterful swordsmanship in order to save the day once again. Because Twilight may have to risk everything she holds dear in order to stop this new enemy, and in this game...everyone plays for keeps.
