Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Leonardo is an artist (at least, that's what he says). He likes playing with clouds, giving them different forms and proudly showing the result to his cavemates. No one dares to say all his sculptures look like some sort of deformed cactus, because no one really wants their backside to become a target for lightning strikes.

On a side note, his habit of "borrowing" clouds gained him a bad name among Daydream dragons, who look at him with deep hatred whenever he passes by.
