One year. It has been one year since the defeat of The Exiled and the restoration of the Foundation of all Dimensions. In that time things have drastically changed for one Twilight Sparkle. She ascended to Princesshood, gained a new castle and a new student on top of that in the form of Starlight Glimmer.

Things couldn’t be more perfect for her.

But when the evil speedster known only as The Reverse-Flash assembles a team of villains to scour the Multiverse in search of a weapon capable of changing the very fabric of reality, The Guardians of the Multiverse must reunite once again to stop this Legion of Doom from changing their very existence.

Can Twilight and the other Guardians stop the Legion from changing reality, as well as help Starlight Glimmer find her place in the grand scheme of things?

Or will the Multiverse be forever changed?
