Queen Chrysalis and her horde of changelings have invaded Equestria, and all ponydom is doom. But buck that noise. Pinkie and Maud Pie need to win Rainbow Dash a Daring Do plushie.
Batsy Fluffentuft (not the most respected of the lunar guards, and in fact on super-probation from Princess Luna herself) manages to escape into the town of Canterlot and have herself an adventure.
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.
