The Dragons are far from human. They are cold-hearted and sometimes cruel and will have no trouble allowing humans to sacrifice themselves for a Dragon cause. Humans are dynastic, family orientated creatures that crave other human contact. Dragons prefer solitude and operate with other Dragons only when necessary. Only the Gemcutter, Amber Drop, and Ruby Heart seem to work in tandem with each other as if they were one being. One thing remains solid, however: There has never been a human Dragon. For a Dragon to become human would mean a connection between humanity and Dragonkind that has never been made since the beginning of time. If this connection were made, who knows what would happen? Would it mean disaster or something better than anything humankind could ever imagine?
