So maybe, dragons lived alongside man-kind peacefully (or perhaps they just ignored humans) until this guys began killing their kind... one thing is sure. Dragons on this universe are, as most of their portrayals, more than just average monsters. I wouldn´t be surprised if Elder Dragons turned out to have their own society or language, and the only reason they attack the hunters so savagely is because the scars of that war is still fresh on them. Or they are a new generation who was taught that humans only mean trouble, and are to be killed on sight.
