Question. When the Great War broke out and all that, did the Listeners band together mainly with Listeners that had the same type of Dragons as them? Sorta seems that way due to how each nation is home to only one type of dragon and all, which brings up another question: if so, how did the Dwarf dudes stick around? If they're physically weak midgets, would imagine that they'd have a long history of getting captured by non-Listeners and treated like livestock, farmed for their magical saliva.

Hell, if it's just their bodily fluids that are magical and their own will is unnecessary, wouldn't every country have at least a farm of these things? Not like those dragons would entertain the idea of 'death before slavery' due to being naturally domestic.

EDIT: While I'm at it, are dragons strong enough that you'd generally need other dragons in order to take one down? Or are there military tactics/special battle units that have been developed so that humans can slay dragons?
