On möbius, it has been years since Sonic's time. And Shadow's son, Blade, has been collecting the chaos emeralds to find out whats wrong with them. And as he finds the last emerald, he is then teleported to Equestria, where he has to help Celestia's student in Ponyville with the Summer Sun celebration day. What adventures wait for him, and who does he fall in love with? Oh crap, spoilers. Sorry.
