In the Harry Potter universe, Patronuses are animal guardians that reflect one's positive energy and are drawn out by the recollection of warm and fuzzy memories. In other words, they're beautiful and magical and pretty much everything we love about the series. Now thanks to Pottermore, fans are able to discover what their own guardians are.
The newly released Patronus quiz starts with an explanatory quote from Remus Lupin. It states, "The Patronus is a kind of positive force, a projection of the very things that the Dementor feeds upon — hope, happiness, the desire to survive." The quiz then asks you to think of your happiest memory, as you're then whisked away into a forest and asked to choose between various words in a quick fashion. In the end, it'll reveal your Patronus, which can be anything from a fox to a dolphin to a butterfly.
J.K. Rowling tweeted about the new quiz and revealed that her Patronus is a heron! The heron is considered to be symbolic of vigilance, tact, and renewal.
Take the magical quiz to finally discover your very own guardian. Once your Patronus is revealed, however, it can never be changed.
