J.K. Rowling pens "The History of the Quidditch World Cup" for Pottermore

Harry Potter fans got a new glimpse into the wizarding world this week, with the help of some new writings by J.K. Rowling.

The author penned a 2,400-word original story chronicling the history of the Quidditch World Cup -- that's the big tournament for the sport played by witches and wizards, for you Muggles -- that's been posted on Pottermore.com, the interactive website devoted to the Harry Potter universe.

Half of the story was published Friday, and the other half will go live next Friday, March 21.

"History of the Quidditch World Cup" chronicles the background on the tournament, how it works and examples of notable and controversial ones from years past -- like the mysterious 1877 tournament that no one remembers:

"The competition was undoubtedly planned: a venue chosen (the Ryn Desert in Kazakhstan), publicity materials produced, tickets sold. In August, however, the wizarding world woke up to the fact that they had no memory whatsoever of the tournament taking place. Neither those in possession of tickets nor any of the players could remember a single game. However, for reasons none of them understood, English Beater Lucas Bargeworthy was missing most of his teeth, Canadian Seeker Angelus Peel's knees were on backwards and half the Argentinian team were found tied up in the basement of a pub in Cardiff."

It also includes some examples from the official rulebook, including that "no dragon is to be introduced into the stadium for any purpose including, but not limited to, team mascot, coach or cup warmer" and "modification of any part of the referee's body, whether or not he or she has requested such modifications, will lead to a lifetime ban from the tournament and possibly imprisonment."

This isn't the only foray Rowling is making back into the Potter universe -- she's also working on a stage play about Harry's early years, writing the screenplay for a film based on the wizarding textbook "Fantastic Beasts and Where to Find Them" and caused a minor (or not-so-minor) uproar among fans when she expressed regret over Ron Weasley and Hermione Granger's romance.
