”Have you...have you ever thought that your dreams were something more? That they were trying to tell you something?” --- Princess Cadance

The Crystal Empire has faced many threats: Sombra, freak storms, Flurry’s chaotic magic, and even the Frozen North itself. Throughout it all, the Crystal Ponies were protected by the Empire’s Heart.

But what happens when a Heart stops beating?

Mysterious and terrible things are afoot in the Frozen North on this cold, silent night, and it’s up to a small group of Ponies and one Changeling to piece it all together before the entire Crystal Empire is thrust into danger. But in the shadows two very different foes are lurking, and both have set their sights on the Empire.

It’s the dawn of a new age, and Equestria’s time to prepare is up.
