J.K. Rowling took to Pottermore, the website made to extensively catalog information about all things Harry Potter, with "History Of The Quidditch World Cup," a revealing look into the history, rules, and culture of the world of Quidditch.
Here are some new details to be gleaned from part one of the history:
1. The Official Guide To The Quidditch World Cup costs 39 galleons ($392.73!), a price that Rowling calls "ridiculously overpriced."

2. The Quidditch World Cup has been held every four years since 1473, though apparently there's a great deal of controversy and debate about that.

3. The rules concerning magic use at the World Cup fill up 19 volumes and include rules about prohibiting dragons and the modification of referee's body parts.
