But then it could be speculated that Braxas is a different species of dragon, since she breathes acid... who knows? They're two different types of dragons, and there's very little concrete information presented about them, so I guess all comparisons made in this blog will be speculation, so I'll count that as a valid point for Hawk's vote.
