History of Magic may have been the most boring class at Hogwarts, but in the Muggle world, J.K. Rowling makes it all worthwhile. In a new Pottermore series about the history of magic in North America, Rowling explained how magic functioned in Native American communities before the Europeans reached America. Unlike their Muggle/No-Maj counterparts, people in the magical world always knew about other continents and communities.
