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.

Rento can be described as a typical Gray Dragon. He has a short temper, and other dragons aren't all too quick in conversing with him. Along with his temper, he also has a tendency to be rather rude to other Dragons, due to the fact that he never cares. Bad events that had occured in the past had left him with a scar, and the final result was him giving up and ultimently caring for anything at all. That was, however, true until he met Victoria, one of the fellow dragons of this cave. He fell in love with her rather quickly, and gave him a reason to once again care.
