During an encounter with Dr. Eggman, Sonic activates a machine that wasn't ready yet, just as the evil scientist planned out. Endowed with the power of the Chaos Emeralds, which Sonic conveniently brought with him, the machine swallows the hedgehog and sends him into a new world, a world that has been divided for centuries and has lost all its magic. Now teaming up with a very optimistic unicorn named Izzy, Sonic will embark on a journey through the uncharted land of Equestria, to unite all the ponies, reclaim the magic, and hopefully find his way back home.
