Stephen Strange failed to figure out how to stop Dormammu with the time loop and as he was about to die from a mortal wound from Kaecilius, the Eye of Agammoto sent his soul back in the 1970's, inside a body of his relative named…Snivellus? And why is he being hung upside down? (Not a full fanfic, just a idea for whoever wants to adopt it!) it! Dr. Strange/Harry Potter crossover.
