Until the Wind Changes
In writing this story, I have tried to adhere to the canons of both the Harry Potter and Mary Poppins universes as closely as possible. In spite of rigorous research, the writing of this story still necessitated embellishment, guesswork, and the invention of characters. All characters/objects/events that I have invented within this story will be denoted with (*) at his/her first mention. Because dating pre-Tom Riddle is not as extensively detailed as the rest of Rowling's universe, I have pieced together inferred some dates and characters. I have also incorporated both the film and book canons for Harry Potter, but with greater emphasis on book canon. In this story I have utilized the book universe for Mary Poppins, as it takes place in the 1930s, and allowed for easier dating. Mary Poppin's characterization is based on both the 1964 Disney film starring Julie Andrews.
