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.

Chimney Sweep, or Sweep, is the one who dug a tunnel from the roof of his cavern to the outside, thus creating a chimney which let all the smoke out. He was given a lot of praise for this, as it is not usually in a storm dragon's nature to dig. He prefers to stay in the mountains, where he toys with the weather and twists the clouds into strange shapes to annoy people. He only cares for himself, and loves making it rain so he floods the caverns lower down, except his due to the clever design of the chimney.
