I agree with you. The only information we got was on the three main and Ginny and Draco. What happened to Luna, the other Weasleys and such? I know we got interviews with it in, but people who can't access then won't know unless some one else tells them.

“J.K. Rowling told TODAY’s Meredith Vieira she “probably will” publish a Potter encyclopedia, promising many more details about her beloved characters and the fate of the wizarding world beyond the few clues provided in the seventh book’s epilogue.

I suppose I have [started] because the raw material is all in my notes,” Rowling said.

The encyclopedia would 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.

Hogwarts, for example, has a new headmaster (“McGonagall was really getting on a bit”), and Rowling said she can see Harry going back to give the “odd talk” on Defense Against the Dark Arts. That class, by the way, is now led by a permanent professor, since Voldemort’s death broke the jinx that didn’t allow a teacher to remain in the position for more than a year.

Rowling said her original epilogue was “a lot more detailed,” including the name of every child born to the Weasley clan in the past 19 years. (Victoire, who was snogging Teddy — Lupin and Tonks’ son — is Bill and Fleur’s eldest.)

“But it didn’t work very well as a piece of writing,” Rowling said. “It felt very much that I had crowbarred in every bit of information I could … In a novel you have to resist the urge to tell everything.”

Rowling said she may eventually reveal more details in a Harry Potter encyclopedia, but even then, it will never be enough to satisfy the most ardent of her fans.

“I’m dealing with a level of obsession in some of my fans that will not rest until they know the middle names of Harry’s great-great-grandparents,” she said. Not that she’s discouraging the Potter devotion!

“I love it,” she said. “I’m all for that.”

“I’m not going to do it tomorrow because I’d really like a break,” Rowling said, laughing. “So you may be waiting.”

It was widely reported that the last word of the final Harry Potter book was "scar" and for years Rowling said that was true.

In the epilogue, which is set19 years after the defeat of Voldemort, Rowling paints a picture of Harry standing on platform 9 3/4, his nearest and dearest surrounding him. In her original draft, the last line was “Only those who he loved could see the lightning scar,’” ….or “something like” that, she told Meredith Vieira in an exclusive interview.

Ultimately, Rowling felt that line was too ambiguous, begging the question about whether the scar was still there or not. She said wanted a more concrete statement that Harry had won; Voldemort had been defeated. The scar was still there, but now it was only a scar.

“I wanted to say it’s over. It’s done.”

Rowling changed the last line to: “All was well.”

“That felt right,” she said.
