Remember that time in 1998 when the world shaken by a violent battle and the fate of the globe hung in jeopardy? No, because that didn't really happen in our world. But it did happen in the "Harry Potter" universe, and one of the young wizards in that battle paid a terrible price.

*Spoilers. Sort of. The book came out in 2007 and the movie came out in 2011, so if you care you really should have read or watched already.*

In "Harry Potter and the Deathly Hallows," the last installment in author J.K. Rowling's epic series, wizard Fred Weasley met his demise during the epic Battle of Hogwarts -- which took place in 1998 within the context of the novel.

On Saturday, the 17th anniversary of the Battle of Hogwarts, Rowling took to Twitter to apologize for brutally killing Fred off.

"Today I would just like to say: I'm really sorry about Fred. *Bows head in acceptance of your reasonable ire*," Rowling tweeted.

When asked by fans on Twitter why she apologized for Fred's death instead of the deaths of a number of other beloved characters, Rowling replied, "I thought I might apologise for one death per anniversary. Fred was the worst for me, so I started with him."

Next up, she'll have her choice of Lupin, Tonks, perhaps Snape, Lavender Brown, or around a thousand other innocent people. Then maybe she can convince fellow fantasy author George R. R. Martin to start making amends for some of the more devastating deaths in his "Game of Thrones" series.
