Flying Dragons are not True Dragons.
They lack extraordinary intelligence, incomparable physical strength, and the strong and perfect Bloodline Power.
As for heritage, it's something they dare not even dream of!
Yet even so, the Flying Dragons, dubbed the weakened commoner's version of True Dragons, possess combat strength far superior to other creatures.
They are only relatively weak compared to True Dragons but relatively strong compared to other creatures!
Their powerful wings give them swift speeds like the wind.
Thick scales and hide allow them to resist most damage from attacks.
Fangs that can easily tear through steel and glands that spray deadly toxins are standard in the extraordinary arsenal of a Flying Dragon.
More importantly, Flying Dragons reproduce much more easily than True Dragons, thus their population grows quite rapidly.
