J.K. Rowling adds more to Pottermore -- with a theme park tie-in

J.K. Rowling has added more to her Harry Potter online universe, Pottermore.

And for the first time, it’s not just words -- it’s also music.

Rowling has written a 500-word story about Celestina Warbeck, the “singing sorceress” who is mentioned in the Harry Potter novels. The story includes, a press release from Pottermore promises, “colourful new details about Celestina’s early years, career highlights and tumultuous personal life.”

Rowling has called Warbeck “one of my favorite ‘off-stage’ characters in the whole series.”

In addition to Rowling’s piece about Warbeck, one of the singing sorceress’ songs has been posted on Pottermore: “You Stole My Cauldron But You Can’t Have My Heart.” It’s the first time that Rowling has posted a song on the website.

Warbeck appears as brief mentions in “Harry Potter and the Chamber of Secrets” (book 2), “Harry Potter and the Half-Blood Prince” (book 6), “Harry Potter and the Deathly Hallows” (book 7).

But the addition of her back story has less to do with the books than it does the extension of Harry Potter into the real world.

The song was recorded at Universal Orlando Resort and features Celestina Warbeck and the Banshees, a band that performs live at the resort’s Wizarding World of Harry Potter -- Diagon Alley. The Wizarding World of Harry Potter -- Diagon Alley opened earlier this summer.

Single-day tickets to the Wizarding World of Harry Potter -- Diagon Alley are $96 for adults, $90 for children. But since it is in Universal Studios Florida, and the adjacent Universal’s Islands of Adventure is where fans will find the Wizarding World of Harry Potter – Hogsmeade, tickets that provide access to both ($136 for adults, $130 for children) may be what kids find truly magical.
