There are only four dragon clans in all the realm. Each is represented by one of the four basic elements earth, fire, air, or water. They are the longest and oldest living civilization around. There kingdoms are hard to get to, and only accessible by dragon means, which means flying. Each clan's kingdom is separated into three levels; the spires where the main den or castle is, the inner city that's lower where all the mid class and work is, and the burrows where all the low down live as well as the underground tunnels and mines.
