Harry Potter fans are a smart, canny, obsessive, smart, obsessive bunch.

So when the official @Pottermore Twitter account tweeted what seemed to be a picture of a black space on Wednesday, everyone pretty much collectively lost their sh*t.

And then they got a-clueing.

Brighten the picture and something mysterious happens. Like a Patronus out of the dark, shining a bright light on the image reveals what looks to be a forest.

A FORBIDDEN forest, perhaps?

While many have suggested it has to do with the forthcoming Fantastic Beasts movie, or something Cursed Child-related, our money’s on a Patronus Quiz, which Rowling herself has been teasing for a while now.

Bet you we get a badger.
