Thanks for the critizism. Actually I haven't reallly thought of that, yet. Mostly due to the very harsh enviroment in which they choose to live, the summer temperatures of the Frozen Wastes are pretty much equal to the winter temperatures in Sibiria, so not much is known of their habits. But I am planning on using one Azure Dragon (A male Great Wyrm) as the nemesis in a future adventure I plan to send my PC's through when the Epic Level handbook is released. So I'll probably write up more on their ecology and mythology. But I have a little more information on them.
Azure Dragons members of a group of superevolved dragons in my campaign-world, of the other members of the group I have only created (so far) the Uhuru Wyrm, which I will post later, but they're basically the first dragon types that settled Areh after the GOO's (Great Old One's for those who doesn't read lovecraft.) where banished. Or rather they helped the gods defeat and banish the GOO's.
But I plan to create 7 more 'superevolved' dragons, one for each of the remaining 7 alignments.
