The Harry Potter saga may have ended with 'The Deathly Hallows,' but a surprising number of now-adults who grew up with the boy wizard and friends are keeping the fantasy series going by actually playing the once-fictional sport of Quidditch.

The rules of Muggle Quidditch are fairly complicated, but it is described as "a full-contact cross between basketball, handball, rugby and mayhem." Suffice to say there isn't as much flying on broomsticks in the game as there was when J.K. Rowlings dreamed it up. However, the players do have to have a broom between their legs at all times.

This real-life version of the sport of witches and wizards was launched at Middlebury College in 2005. The game has been growing since, and now the International Quidditch Association features 150 teams around the world.

But Quidditch has come to a crossroads of sorts. While the yearly Quidditch World Cup continues to be a popular event, it costs about $100,000 to stage, and dues and merchandise alone won't cover that price tag.  So the IQA is looking for advertising partners. However, the organization also worries that Warner Bros., which owns the rights to 'Harry Potter,' will squash the sport with a cease-and-desist if it gets to big.

What do you think? Is there enough room on the sporting landscape for Muggle Quidditch? You can watch a video explanation of Muggle Quidditch below.
