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.

Adopted by Viktor when he was an egg, Remus wants to deserve the parental love he shows him. He doesn't like wandering with other, more playful, male dragons: he prefers the company of the two guardians, Roland and Francis.

He's very responsible: since he loses his temper easily he tries to avoid contacts with humans and other dragons, especially young blacks who tend to bully neighbours to show their power, so he often goes hunting at night.
