After JK Rowling’s recent interview with Today’s Meredith Vieira, hope is not lost for Harry Potter’s fans who have tried by all means to convince the author to continue writing about the boy wizard’s adventures.

During a tell-all interview, apparently her first one since the seventh and final book was released, Rowling told Vieira that she "probably will" publish a Potter encyclopedia, from which fans will find out many more details about their favorite characters as well as more news about what will happen with the wizarding world, she will try to reach some sort of closure.

"I suppose I have (started) because the raw material is all in my notes," Rowling said.

The next book, Harry Potter Encyclopedia, will most likely include back stories of characters she has already written but had to cut for the sake of narrative arc ("I've said before that Dean Thomas had a much more interesting history than ever appeared in the books"), as well as details about the characters who survive "Deathly Hallows," characters who continue to live on in Rowling’s mind in a clearly defined magical world.

Rowling often spoke in interviews about the moment she finished writing the book but now that the book is out and she no longer has to keep its content a secret, she told Vieira that it feels "incredible" to finally have ended the saga that will forever define a generation of readers of all ages.

"It feels great, to be honest with you. It's a really nice place to be," said Rowling.

The writer admitted she was very hard to live with for a while after concluding the book.

"I felt devastated," she said, explaining she was just drained emotionally after having completed “Deathly Hallows” which sold 8.3 million copies in the first 24 hours since its release.

"It was this amazing cathartic moment," she told Vieira. "The end of 17 years of work. And that was just hard to deal with for about a week. And it's very much tied into things I've done in my life for seven years that brought back a lot of memories of what had been going on in my life when I started writing."

However, her grief turned into satisfaction, as she feels"a big sense of achievement."

"I mean, I am sad. But I've been sadder," she added.
