"The gods have alread decided. I am the will of this world. Can you bear the earth's will?"
Among the many dragons, there are giant, extremely powerful dragons that go by the name Bahamut. They swoop down and suppress conflicts and disputes between other dragons. Their judgement is always fair, and no one ever objects. When someone has been judged to have harmed nature, Bahamut passes divine punishment as a representative of all dragons.
