(A Persona Crossover, accessible to those who have not played the games)
There is a problem plaguing Ponyville. For countless fillies and colts, every single night is filled with visions of their greatest fears, and it always seems to be at the same time: just after midnight. There are even rumors of a dark world where Ponyville is shrouded in an impenetrable darkness, and everything is still, as if time itself has stopped. While parents brush it off as part of their childrens' nightmares, the real nightmare for Ponyville is about to begin...
Cornerstone, a new resident of Ponyville, would prefer to simply continue his work building and designing homes, rather than dwell on these rumors. Unfortunately, when a pair of murders rock the town, he and a certain six mares and dragon assistant all find themselves drawn into the mystery of this other world. Thus begins the race to find its origins, as well as the murderer using it for their own nefarious purposes. And it all starts with a single question:
"Just who are you?"
"Why, you're me... and I'm you."
