The complicated romantic troubles of the first Grasshopper recall many characters with similar subplots (Spider-Man, for instance), as does the unlikely family background of the second.

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.

Any new works taking place in this universe are released under the "J. K. Rowling's Wizarding World" brand.
