In the wake of the disastrous battle with the Chimera, Sky now rests in a coma within Canterlot Palace. The Council has become desperate to find a way to stop the monster's onslaught, but without Sky Streak, their options are growing thin. Twilight and the bearers of the Elements of Harmony prepare for an uncertain showdown with the Chimera, but with little knowledge of the Chimera's true abilities, their chances of success remain in doubt. But somewhere within Equestria, a lost spirit wanders in search of his identity. And when he finds it, he may discover the key to vanquishing the darkness has been with him all along.
