Have you ever wondered how a pony's mind came to be, how it was formed? Some ponyfolk say that Princess Celestia formed their minds. Others disagree with that statement, saying that science is the explanation. One mare is determined to find the answer to the question by going deep into her own mind, even past the subconscious part of it. There she is startled and shocked at what lies beneath it. She might even be trapped in Limbo forever.
