The Lesser Dragons are reclusive, but fiercely protective of their strongholds. They reside mainly in the mountains, and can easily be befriended and allied with. They regard Cel'aksh as their patron, however, which means that Celt might have a better bet at befriending them. They are a society where the females are more powerful then the males, meaning the traditional gender roles are reversed.
For what they look like, think Asian-style dragons. I don't have any scenes with them yet, as the book takes place in the north.
Anything else you'd like to know? They aren't common in Ichondor, they're just the only race that fit there.
Nothing constructive is common in Ichondor - the Wastepaper Nation, as it's known unofficially. But that's the book - this is your chance.
