(Post-Movie)

After the defeat of the Storm King, peace had returned once again to Equestria. But things like peace are pulled out of Princess Luna's mind when she has a vision of an evil force plotting to conquer Equestria after they steal Crystals and destroy the inhabitants of another world.

Accompanying her on this journey are Twilight, Spike, their Ponyville friends, Shining Armor and Princess Cadence as they join forces with Cecil Harvey and a host of other warriors as they take on Golbez.
