Anyone ever thought of starting a dueling club of some sort? It might be difficult to organize, seeing as some of us use magic and some don't, and those who do use magic seem to do it differently depending on where we come from, but still. Just because it poses a challenge doesn't mean it shouldn't be attempted. We could try to pair people up with similar abilities, lay down a few ground rules, and have some fun!
