Before Princess Celestia, Princess Luna, and Starswirl the Bearded no one at all there was only water, trees, animals, and wonder in the planet. Then with out wording to gem like gods which are called "TimeLords" arrived in the hart of Equestria to do one thing and one thing only create a new species to impress there own kind at all cost. One of them was named Thanos which means Harmony in there own ancient languish believed that if he made something that is more Beautiful but deadly giving them his own TimeLord magic to defend them selfs and stop unknown threats it will change the universe forever. With he created the Unicorns, which have a weaker magic level then the TimeLords but get stronger every year, Pegasus, that Watch the sky's and help with the wether, and Earth ponies that live there lives to live in there own world.....However his own brother "Legion" only saw of how useless, and discussing they are witch will be the end to both of them.
