Blue Dragons are vain and territorial. They are one of the dragon varieties best adapted to digging in the sand. A blue dragon’s scales vary in color from an iridescent azure to a deep indigo, polished to a high gloss by blowing desert sands. The size of its scales increases little as it ages, but do become thicker and tougher. Its hide tends to hum and crackle faintly with the build up of static electricity.These effects intensify when the dragon is angry or about to attack, giving off the odor of ozone and sand.
