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.

Cumulonimbus Griseus aches to bring about a tornado. It is his greatest ambition. It is also extremely difficult and dangerous, and on the days he has felt powerful enough to do it, he has also felt nervous, and made excuses about why today wasn't the day. Instead, he likes to make the blackest, thickest clouds possible, and persuade them to rain on the others when they are breathing fire. He really doesn't approve of dragons breathing fire, even though it is in their nature and he does it himself. They get very cross when he douses their flames, and don't let him have any dinner—not least because without flames, they can't cook it all as well as sometimes. He'd quite like to make friends with Flaming Evil, and use his electricity to improve the storms he creates—but he's all too aware that Flaming Evil is likely to let him down at a critical moment, so he soldiers on alone.
