Tough
How tough is Grabon? Compared to other dragons he is obviously not a puff ball or wimp, but how tough is he? You should have gotten the sense from Rok and Thane that they are pretty rough and Grabon and Heron used to fight for coins as well as pleasure, using their fighting ability as something to wager on. That makes Grabon not only a jock by human standards, but an intellectual phillosopher. He is really setting up his territory differently, not only allowing humans but recognizing them as equal to his dragon clan members. He allows unmated members of his clan to keep their youngsters to raise, he eats human food and serves it to people in his nest. His territory is open to all manner of visitors to attend a market where they sell human and dragon made goods and food. His clan members are not all focused on a single task… well they are, teaching humans and dragons that they are more similar than different. He is a revolutionary!
