Dragons? Fights? You've got me intrigued to say the least~ Everything seems alright and pretty straight-forward to me. The only questions I really have are: 

Is there a name for somebody who has bonded with a dragon? Like Rider or Tamer or something?

And how does a person traditionally end up with a dragon? Is it somebody's job to choose who gets the ability to bond with a dragon? Or can, say, a human kinda just stumble upon an egg out in the wild for one reason or another?
