Sleeker, larger, and more leathery than their smaller purple cousins, the blue dragons are the wraiths of the seas, lakes, and rivers. Their wings are smaller, so they tire more quickly in the air, but their powerful limbs and tails, usually adorned with aquatic fins, help them swim faster and more silently than the sleekest leopard seal. They are usually hornless, instead sporting fins, frills, or air bladders along their bodies.
