Harry Potter and the Prisoner of Azkaban is the best of J K Rowling's Potter series. We're not here for an argument, it's just a fact, okay?
Part of the book's brilliance is owed largely to the dark, foreboding sense of peril that Rowling introduces to the series: Dementors, the deathly cloaked figures that can literally suck the happiness out of people. Accompanying these bed-wetting horrors was the series' most badass spell: the Patronus Charm, a "kind of positive force" embodying that hope and happiness, forming a creature unique to the character of the wizard conjuring it.
If you've made it this far, you're undoubtedly a fan of the series (good for you) and haven't uttered something along the lines of, "Seriously? Harry Potter? F*ck this..." before heading elsewhere. You'll thus be intrigued to know that J K Rowling herself has written a new feature for the Pottermore fan site: a Patronus Charm quiz, that will (you guessed it) reveal your Patronus.
Don't lie, you want to know what yours is, right?
Users are asked to answer a series of 'personal' questions, choosing from a selection of words as they appear on the screen.
Our quiz taker was presented with a Greyhound. No idea why. They share no personal affinity for the animal and describe themselves as a "cat person" but there you go.
Since the feature's launch, photoshoppers have already been doing some incredible work on sharing some fake Patronus options - which even Rowling herself enjoyed, retweeting the following effort...
The author had to confirm that it was just a joke, as we lost a shred of faith in humanity and wondered if there was any point in carrying on if people needed reassuring this was a gag.
So did we, Rowling. So did we.
