Once upon a time, in the magical land of Equestria there lived the three tribes of Ponies. The strong Earth Ponies, the brave Pegasis, and the magical Unicorns.
Each tribe lived happily upon their own lands, each land being a bubble of safety and peace sheltering each tribe from the violent and deadly magical storms that almost always raged right outside their territories.
Travel between lands was always dangerous and fraught with risk on those rare days when the storms were quiet, for no pony could ever be sure how long the corridors between lands would remain open. So each tribe lived by themselves, rarely if ever making contact with each other and would continue to do so for all timeā¦ or so it seemed.
