5 Years after the Royal Coronation of Twilight Sparkle, much of Equestria has fallen into a sleepy peace. Peace has allowed some of the Mane 6 to settle down and focus on other things besides saving the world. Over time, Fluttershy and Bic Mac have decided they have feelings they further want to explore, while romantic tensions and confusion begin to finally surface between two other members of the Mane 6.

Mean while, an expedition to the Macintosh Mountains leads to an amazing and terrifying discovery. With a forgotten evil back on the rise and members of Ponyville and Canterlot mysteriously being taken by what witnesses describe as an Alicorn, the Elements of Harmony are about to be tested like never before. The cost to defeat this rising evil may prove to be too high as the very soul of one of our heroes is put in jeopardy.
