In the moons of peace that have passed since Twilight Sparkle's ascension to the throne, no threat has ever been as great as the kind presented by the three greatest villains in Equestria's history. Little does the princess know that the past will be catching back up to her, and everyone else, very soon.

A unicorn named Toasty Blanket has come all the way to Equestria from another realm to find a child that she's been separated from for all these moons. Her travels have taken her to Ponyville, but in order to find what she seeks, she must talk to the princess in Canterlot. Having been stuck for so long in a place cut off from the natural world, she's going to learn the hard way what happened with her little one.
