HP Contrarian

The boy lands four feet from the Sorting Hat onto the stool in September 1993 without a wand, an unfamiliar surname, and the wrong instinct. In one week, he attempts his first Lumos spell in an empty corridor, but it makes the area darker.Cael Mourne's magic works the inverse of its command. Reversed Lumos. Reversed Stupefy. Reversed Accio. Everything he casts becomes the inverse version of itself.Within two months, a Slytherin Prefect by the name of Pansy Parkinson has started keeping tabs on him from the other side of the library without saying a word. In two years, he has Snape's tutelage in the form of a blunt getup. In four years, Cael starts to wonder if the inverse of cutting off life isn't perhaps something else altogether.Transmigration AU for Year 3 and onward.
