This year has been a resurgent year for the Harry Potter franchise, and Pottermore has been at the epicenter. In addition to publishing the “History of Magic in North America” series and an upcoming series of Hogwarts-focused ebooks, Pottermore has recently added a few original J.K. Rowling sketches to various parts of the website. Surprisingly detailed, the sketches appear to date from when Rowling was working on Harry Potter and the Philosopher’s Stone, and most depict scenes from that first book.

For instance, one of the sketches depicts the poltergeist Peeves, a big presence in the early Harry Potter books who never made it on-screen. Another draws a lineup of Harry’s Gryffindor friends, but Rowling’s label calls one of them “Gary.” There is obviously no one named “Gary” in Harry Potter, so a fan asked Rowling about this on Twitter. She replied that Dean Thomas had originally been named Gary, after someone she knew.

See a few more sketches below.
