When Starlight Glimmer steals a time travelling spell, threatening the fate of Equestria, Luna decides it's time to find out why Celestia hasn't been doing anything to stop it.
Luna's betrayal plunged Equestria into chaos. In a bid to restore harmony, Celestia calls upon the very ponies who once served the Nightmare to drag the world from the ashes – and find the monsters who would threaten our future. I am one such pony.
Princess Luna disappears from Equestria with hopes of saving the world and is accompanied by the enigmatic Sombra. Meanwhile, Celestia tries to bury secrets as immortal as she is and Cadance must choose her loyalties carefully...

Luna has retaken her rightful place on the throne of Equestria alongside her sister, Celestia, but while Celestia rules the day, Luna's night brings forth a monster. A monster the likes of which Equestria has never seen. A Beast of Flesh and Metal
