Fictional universe of Harry Potter The fictional universe of British author J. K. Rowling's "Harry Potter" series of fantasy novels comprises two distinct societies: the Wizarding World and the Muggle world. The Muggle world is the series' name for the world inhabited by the non-magical majority, with which the Wizarding World exists coextensively, albeit mostly remaining hidden from the non-magical humans. The plot of the series is set in 1990s Britain, but in a veiled and separate shadow society wherein magic is commonly used and practiced, and those who can use it live in self-enforced seclusion, hiding their abilities from the rest of the world. The term "Wizarding World" refers to the global wizard community that lives hidden in parallel with the Muggle world; the different terms refer to different communities within the same area rather than separate planets or worlds. Any new works taking place in this universe are released under the "J. K. Rowling's Wizarding World" brand.
