4. He made his creator the first literary billionaire
Before J.K. Rowling, no writer had ever become a billionaire from just putting words on the page -- not even Stephen King. But, she ended up dropping off the Forbes list of billionaires partially because she was too charitable. That's definitely the coolest way to drop off a list of billionaires.
5. Many of his best spells come from Latin
Harry Potter is an English boy -- he's got the "trainers" to prove it -- but many of the spells he uses to thwart off evil come from a dead source: Latin. J.K. Rowling studied Max Fischer's favorite language when she was a student at the University of Exeter and must have been taking copious notes because spells like "Crucio" and fan-favorite "Wingardium Leviosa" have their origins in the classics.
6. And many of the wild things that happen to him come from folklore and alchemy
In addition to peppering her prose with Latin, J.K. Rowling mastered the art of dropping bits of meticulous research into her writing. The use of folklore was particularly unnerving to Christian groups, who warned parents about the books, but Rowling herself has never claimed to be a witch. "I've never wanted to be a witch, but an alchemist, now that's a different matter," she said in a 1998 interview. "To invent this wizard world, I've learned a ridiculous amount about alchemy. Perhaps much of it I'll never use in the books, but I have to know in detail what magic can and cannot do in order to set the parameters and establish the stories' internal logic."
