Ice Dragons are the least intelligent of dragonkind, but the most physically powerful and dangerous. They breathe freezing air that freezes most prey solid, which is how they prefer to eat it.
Ice Dragons do not have the intellect to truly appreciate human culture, philosophy, and society, and tend to have the poorest hoards. They content themselves with making lairs in deserted human castles and villages, soaking in what human culture they can understand from the human ruins they call home.
They have difficulty recruiting human agents because they live so far in the sparsely settled north, but though evil, they are devoted and loyal to a human agent once they have found one.
