J.K. Rowling announced Friday that she will be releasing 12 new “Harry Potter” stories on the website Pottermore.com starting Dec. 12 as a part of the upcoming Christmas celebration. A newsletter to Pottermore members reportedly revealed that they would need to tweet #PottermoreChristmas to unlock one story each day.

One of the stories that will be published as part of the “festive surprise” will contain details about what Rowling thinks about the young wizard’s enemy, Draco Malfoy, The Telegraph reported. The stories will be published every day until Dec. 23.

“With wonderful writing by J.K. Rowling in Moments from ‘Half-Blood Prince,’ shiny gold Galleons and even a new potion or two, make sure you don’t miss out,” the newsletter reportedly read.

On Halloween day 2014, Rowling released a story featuring the witch and former Hogwarts professor, Dolores Umbridge, who first appeared in the fifth Harry Potter book, “Harry Potter and the Order of the Phoenix” published in 2003.

Rowling revealed that Umbridge’s character was based on a real life person and was inspired by teacher Rowling once had.

"Her desire to control, to punish and to inflict pain, all in the name of law and order, are, I think, every bit as reprehensible as Lord Voldemort's unvarnished espousal of evil," the author wrote. "Dolores is the only person, other than Lord Voldemort, to leave a permanent physical scar on Harry."

Rowling is currently working on a screenplay for the first film in the "Fantastic Beasts and Where To Find Them" trilogy, which is scheduled for a November 2016 release.
