HARRY POTTER'S fate may finally have been revealed - but millions of fans around the globe still have burning questions about JK Rowling's wizarding world.
The epilogue of her final book only offers clues to what happens in the years after Harry's schooldays, so fans will be delighted to hear plans for an encyclopedia are under way.
In an exclusive interview with American television, Rowling confirmed she "probably will" publish more details about her beloved characters.
She said the encyclopedia would include background stories of characters she has already written but had to cut - such as Harry's school friend Dean Thomas.
She also said the book would include details of a new headmaster at Hogwarts, and who was teaching defence against the dark arts at the magical school.
"I'm not going to do it tomorrow because I'd really like a break," Rowling said, "so you may be waiting".
In the interview, Rowling said it felt "incredible" to have completed the series she began 17 years ago.
But she also revealed how she will miss being able to retreat into Harry's fictional world.
Harry Potter and the Deathly Hallows became the fastest-selling book in history when it was released on Saturday.
More than 11 million copies were sold in the first 24 hours in the UK and United States.
Rowling said it was a "big sense of achievement" to bring the popular series to an end.
QUESTIONS: Rowling takes part in Castle interview
"I mean I am sad, but I think [I was] sadder immediately after finishing writing," she said.
"I felt devastated. For about a week I was hard to live with after finishing this book.
"I think the whole thing, it was this amazing cathartic moment, the end of 17 years' work, and that was just hard to deal with for about a week.
"It brought back a lot of memories of what had been going on in my life when I started writing."
The NBC interview took place at Edinburgh Castle yesterday morning, with film crews from the US network setting up from 6am.
The interview meant that some areas of the attraction had to be closed during filming.
During the recording, where 14 fans were also able to pose questions, Rowling openly discussed the plot of the latest book and the decisions she made on the fate of certain characters throughout the series.
She revealed why she could not bear to kill off one popular figure - originally earmarked to die in Harry Potter and the Order of the Phoenix - but admitted some of the deaths in Deathly Hallows were hard to take.
Talking about the climax of the book, she said: "I didn't cry as I was writing, but when I finished writing, I had enormous explosion of emotion and I cried and cried.
"That was partly because of the content — and partly because it had been planned for so long and been roughed out for so long. And to write the definitive version felt like a huge climax."
Potter fans' night ruined as parked car smashed
A GROUP of Harry Potter fans found a suspected drink-driver had wrecked their car as they were queuing to buy the eagerly-awaited final novel.
Nurse Julie Ferrier and her son Jamie, eight, spent three-and-a-half hours queuing at Waterstone's on Princes Street to get Harry Potter and the Deathly Hallows.
But when they returned to their car on Regent Road at about 1.30am, they found it had been written off in a smash. A driver had crashed into the Vauxhall Agila and shunted it along the road.
The accident ruined what was supposed to be a big night for the pair, who were with friends Linda Johnston and her 15-year-old daughter Amy.
Mrs Ferrier, 31, of Cockenzie, said: "Jamie was really upset by it all and I was just glad I was out with friends, as I think if it had just been the two of us I wouldn't have coped so well."
The driver of the other vehicle was taken to hospital with minor injuries and a blood sample was sent for testing.
