"The northern dragonoids have a way of expressing emotions that goes a long ways back in their history. Whenever they wish to express an emotion to the nature or the world they simply hum either alone or with others. Words and instruments may be used when doing this in company, but more commonly there are no words included in these melodies as they believe that nature and any otherworldly beings which may be listening cannot understand their words. Therefore they convey the meaning of each song most commonly through melody alone. It is not very uncommon that someone who is wracked with emotion and creates one of these melodies can notice one of these otherworldly beings from the corner of their eye. Once the melody is finished the being will vanish and the person will be cured of any mental distress they previously had. Maybe these beings are intrigued by these emotions or perhaps, they too, have something they need reprieve from."
