A new arrival comes to the not-so-sleepy hamlet of Ponyville, in the form of an amnesiac pegasus who appears in the town square in a burst of magic. Though the pony called 'Rainy Daze' seems to settle in quickly, she is harboring three important secrets:

One, that she is not a pony at all. Two, that her memory is just fine. And three, that she wants to get the hell out of this crazy place!

When an ancient threat resurfaces in the badlands, it falls to Little Strongheart and the bearers of the Elements of Harmony to face it. Can they vanquish the forces of evil before all of Equestria is overtaken? Can both pony- and buffalo-kind hope to stand before the coming darkness without destroying one another in the process?

Twilight Sparkle has, she is convinced, fallen under the effects of some bizarre hex. Why else would she be so captivated by a certain chartreuse lyre-player? Why else would her cheeks burn up every time she talks to Lyra Heartstrings? It must be some sort of magic. Right?

... Right?
