Anyway, it’s unthinkable! Dragons and knights are born enemies. They need to be enemies just like dogs hate cats, cats hate mice and mice hate scientists. Without somebody to hate where would all the hate go? The hate would just boil up inside you, eat away and cause you to have indigestion then a heart attack. We need to release the anger, and we release it on dragons who release it back on us. We slay them and they roast us. It is the natural order of things, Emma.
