J.K. Rowling will be releasing a new “Harry Potter” story featuring the witch and former Hogwarts professor, Dolores Umbridge, on Halloween day 2014. The announcement was made Friday on the website Pottermore.com.

The story, which will be released on Oct. 31, will include Rowling’s "revealing first-person thoughts" about Umbridge, who first appeared in the fifth Harry Potter book, “Harry Potter and the Order of the Phoenix” published in 2003. The role was played by actor Imelda Staunton in the film adaptation of the series.

“Umbridge is not only one of the most malicious Potter characters, she is the only person other than Lord Voldemort to leave a permanent physical scar on Harry,” a statement on the website posted Friday reportedly read. “The new exclusive J.K. Rowling content provides a rich, 1,700-word back story about Umbridge’s life filled with many new details, as well as Rowling’s revealing first-person thoughts and reflections about the character.”

In July, Rowling released a story featuring a now-grown Harry Potter. The 1,500- word story saw a 33-year-old Potter reunite with Ron Weasley, Hermione Granger, Luna Lovegood and Neville Longbottom for the final match of the Quidditch World Cup. The website reportedly crashed following the release of the story due to the volume of traffic.

Rowling is reportedly working on the screenplay for a Harry Potter spin-off, based on "Fantastic Beasts and Where to Find Them," which is scheduled for a November 2016 release.
