An abnormal dragon is one whose skeletal make does not fall within the recognized structures of a dragon and dragon mast.
Abnormal dragons may possess unusually big head, wingspans that are times three or more of its body size, or a body length that is far bigger than its wingspan.
Such dragons are rare and dangerous to be bonded to as their inadequate body size makes it hard to take proper flight with them.
