29 Of Quills and Quidditch » by DeathRainbows Chaos Control goes wrong. What else is new? Sonic and Shadow were not expecting to have to go to magic school. Neither were Harry and the Golden Trio expecting a duo of hedgehogs to invade their beloved Hogwarts. Look out, Wizardkind, chaos has arrived. Aka there aren't enough Sonic crossovers, so I decided to make one. There will be little romance besides canon pairings. Enjoy!
