Despite the fact that nopony ever really likes to acknowledge it, there's always been a sort of caste system in Equestria. After all, it was unavoidable--the Pegasi could soar beautifully through the air, the Unicorns were great magicians, and the Alicorns were all that with a little icing on the top. So what abilities did the Earth Ponies have? Horse apples. Enter Applejack, Earth Pony, Element of Honesty. Good farmer but not good for much else. But Applejack has a secret: she can feel It. She can feel It babbling through the streams and lacing the songs of birds. Whatever It is, though, It doesn't seem to be very good news for Equestria. And after a strange rift in the mane six's friendship develops, Applejack is determined to expose Its evil once and for all, even if it means taking drastic measures to do so... Dark fic, but not grimdark.
