The Harry Potter universe is getting a little bit bigger. According to CNN, Pottermore Publishing will be diving into the Wizarding World further with a new series of non-fiction e-books that explain the "traditional folklore and magic at the heart of the Harry Potter series."

The four books will be based around classes that Hogwarts students might have taken, revealing where the charms, potions and other elements of magic were pulled from for the original series. 

The first two books, A Journey Through Charms and Defense Against the Dark Arts and A Journey Through Potions and Herbology, will hit digital shelves on June 27. The remaining two, which will focus on divination and magical creatures, have not yet been given a release date. 

It's been over a decade since the original run of Harry Potter books ended. However, the series has remained in the public imagination thanks to stage productions, universe-expanding films like Fantastic Beasts and Where To Find Them and diegetic texts like The Tales of Beedle the Bard. Additionally, the online resource Pottermore has provided fans of the Harry Potter universe with a digitally interactive space. 

Beyond that, fans have been given the opportunity to immerse themselves in the world of Harry Potter thanks to the Wizarding World theme park in Orlando. And there's always plenty to debate about nearly any time J.K. Rowling gets near Twitter.

Recently, Rowling explained the nature of the relationship between Hogwarts headmaster Dumbledore and his rival Grindelwald. In a recent featurette, the author insinuated that the two had a sexual relationship. “Their relationship was incredibly intense. It was passionate, and it was a love relationship,” Rowling said. “I’m less interested in the sexual side – though I believe there is a sexual dimension to this relationship – than I am in the sense of the emotions they felt for each other."
