Monster finds problems fitting in and getting used to her new world in Ponyville. To help adjust, she reaches out to Princess Luna who has many of the same problems now that she is recovering from being Nightmare Moon.
"Even as they lied to me, Even as I broke- Even as the world crumbled, Even as it died, Even then you searched for me, And tried to reach my side." Twilight Velvet is going to find her daughter. No matter what it takes.
Twilight assumes that her life is all she's ever known, but what if it's just one of many? What if everything—her personality, her world, her identity—was nothing more than a fantasy?
Applejack, despite her best efforts, has been watching red ink replace black in the farm's ledgers for over a year. She can't see a way out of her financial problems or the growing depression threatening to cripple her.
When Twilight eventually wakes up, she isn't in her library. She isn't even in Ponyville. With a more minor case of amnesia and lots of questions, it becomes more and more clear, that Twilight isn't sane anymore.
