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.

Oposs'aesthyr has perfected a specific range of weather magic to employ against those who anger her. Like most of her kind she is easily angered and regularly thrashes around in the dark recesses of her cave in fury. After her initial rages held in seclusion, she emerges and takes to the skies, twisting and turning with barely contained rage. She disperses the clouds entirely, she stills the winds too, leaving nothing but the burning heat of the sun; small rivers dry, water levels drop and crops burn as she leaves the area without respite for many days, often weeks. After calming down and feeling somewhat remorseful she calls a calm breeze and a fine rain that descends on the parched lands, delighting the forgiven dragons and people around with a display of rainbows created by the effect and the restoration of cool winds and water. It is a blessing that she is rarely angered!
