Concept: In misty valleys, behind waterfalls, and sometimes cloudy mountaintops, these dragons live solitary lives. They do not fly; they use their wings to move their fog clouds to useful places. The ice spell can be used to freeze opponents, but can also be used to freeze a small area of ground, like any inclined ground that lies between a dragon and its opponents. Their hordes consist of tribute from peasants and the goods that adventurers drop when they die.
