During her entrance exam, Twilight Sparkle was on the brink of failure, however a surge of magic suddenly exploded from her and she succeeded at hatching the egg of Spike the dragon, but she can't remember anything prior to that.

She was told tales of her brother Shining Armor, her babysitter Cadence, how she admired Celestia, how she studied magic with fervor, how she used to be a purple unicorn and not a gray earth pony.

At times she struggles with the feeling that this isn't right, as if she isn't really Twilight Sparkle and the real one is trapped somewhere, sleeping dormant, dreaming of freedom.

A life of trials not meant for her await and Equestria hangs in the balance.
