There are two main types of dragons: European Dragons and Chinese Dragons.
The European Dragon is a malevolent creature that looks like a gigantic serpent or lizard with wings. They have thick scales like either a fish or a snake. Dragons generally also have short legs, which they use to get around on foot. They use their leathery wings to fly long distances and over mountains and large stretches of water. They will destroy anything in their path by crushinging it or burning it with their fire-breath. The breath of a dragon has also been known to cause plagues. They typically live in caves and frequently guard treasures.
Chinese Dragons are benevolent creatures that are friends to humans. They are symbols of power, strength, and virility.
