We all know the gist: during the first Nightmare Night after Princess Luna returned to Equestria she went to Ponyville, tried to mingle, got rejected, terminated Nightmare Night and got it reinstated in one single night...

But in this universe we're visiting, after that, the existence of a certain common brown Alicorn, brought something else that Night...

Now, With the Nightmare resurfacing on the eve of all saints' days, the Mane 6, Princes Luna and the Ponyvile Alicorn Alfonso Rodriguez will have to stop the Nightmare from gaining a new host, but in the shadows something else might lurk too...
