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.

Milly is a cruel dragon; she doesn't let anyone get in her way. She spends a lot of her time flying through the air creating terrible storms. If someone bothers her while she is eating, sleeping, or just sitting down, she won't hesitate to attack them until they run away from her. Milly can't stand hatchlings that aren't her own species, so she just stays away from hatchlings.
