It is said that the Princesses are immortal. It is said that they've been here since the beginning and will be until the very end. It is the truth. In some ways. The full truth is hidden away, erased from history. But there still is one string that binds everything together. One thing that holds it together. This thing is the only reason why Equestria still exists.
