After a spell she shouldn't have cast, Twilight wakes up to find everything she knows and loves changed into a monstrous mockery of itself. She has one solace - a pony to be her only brightness in a world of dark. But what toll with the horrifying nature of reality take on her psyche, and what path will she take to go back to the way things were? Crossover with the amazing visual novel Saya no Uta, with art inspiration by Rose (it's not a direct translation).
