Things didn't go, as planned, in the Crystal Empire. Sombra was defeated, but he used a clone to try and take the Crystal Heart. Now, he has Twilight Sparkle captive, and trying to force her to become his student. Celestia, stricken with grief, sends every pony she has to search for her valued student, who was like her daughter... Not knowing, another has come to help. A being that has been around far longer than any other. One that was old when Celestia was but a foal, and has sensed the trouble within Equestria. Knowing he could not physically help, the being decided to assist Twilight in learning a power that many consider dangerous... But it is, truly, the only way to defeat Sombra.
