To fight back against those slaughtering them during the crusades, Osmos Gien crafted a powerful key to alter warrior bloodlines and give them the ability to take to the skies. It was during the 1200s that dragon-warriors came to be. Since then, those descendants of dragon-warriors were also gifted the ability to shift. Royals use these warriors as protectors of the people, Hansian scouters, and as personal guards.
