Although the Harry Potter books and movies were released some time ago, there continues to be an insatiable thirst for more content among fans of all levels.

And while seven core books and eight movies might seem like a lot, it feels considerably less substantial when spread over 27 years - a milestone we've just reached, as the first book was published on June 26th, 1997.

Since the last book came out in 2007 we've had a few more films and we've had scribblings published here and there. We've even had a few prequel stories, but for the most part, extended lore pertaining to the Wizarding World is...Somewhat limited.-
