After fifty long years imprisoned for her heinous crimes Rarity faces the final phase of her sentencing.

This story is a sequel to A Griffon's Fate

The griffons are attacking Los Pegasus, and Celestia has sent her guard to protect the city. Everypony thinks that the royal guard will be victorious, but when a lone pegasus returns to Canterlot and reports that the guard ponies have been wiped out, Princess Celestia quickly orders a search and rescue effort be made. By the time the first rescue team arrives the city has been abandoned and dead bodies of ponies and griffons litter the streets.

During the recovery effort, one pony finds a corpse clutching a book to his chest. It turns out that this book is the dead pony's diary, and it is the only written account of what happened during the battle. This is that story;

(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."

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?
