When the energy of the Crystal Heart shattered the evil King Sombra's body, everypony thought the ruthless tyrant destroyed. But it is not so...

King Sombra was more prepared for defeat than anypony thought. Deep within the frozen arctic, the Crystal Tyrant revives his body and reconquers the Crystal Empire overnight, incapacitating both Shining Armor and Princess Cadance in the process. Sombra has also learned from his past mistakes, wreaking havoc when the Equestrians least expect it.

War is coming, and Sombra has no intention of losing a second time. It will take all the strength of Twilight, her friends, and many of their previous enemies to stem the tides of darkness and stop King Sombra once and for all. And this time, the Power of Friendship may not be enough.

Rated T for some depictions of war violence and gore, along with some swearing.
