My Little Pony: the Princess' Disciple

A pony's life is like a clock, it only moves forward at different speeds, and no one knows when it will stop. While all ponies were walking forward, Sunburnt, Celestia's favorite student, was walking in the opposite direction, traveling through different timelines. It is not an exaggeration to say that he knows the past and present, because these are all things he has seen and experienced with his own eyes. He knows the ancient times, the past, the present, and even the future very well. He himself is not a savior, but he compares himself to a guide. The task he gives himself is to guide the savior to complete her task. This is also the only task given to himself by his future self.
