Something I just realized: Oswald would probably have a unique accent. You have the four major Kingdoms: Mistral, Vacuo, Vale and Atlas, each of which probably has a respective accent that most people would at least have a vague idea of, even if they'd never met someone from another Kingdom. 

But Oswald? He's from a village nearly two hundred miles outside of Vale (I looked about about how far an ox-drawn carriage could move in a day, it's 10-12 in a 10-hour day- but if you push em a bit harder you could make 12-15, since oxen are sturdier than horses- and used my predetermined two-week travel time to figure that it would be about 189 miles off. So, just under two hundred overall.) So wouldn't it figure that he'd have an accent few people would have heard before? I bet he'd sound really freaking weird to some people. 

This could be interesting if I decide to fuck about with it.
