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.

Aeillos is the offspring of a Silver dam and a Gray sire. His Gray coloration masks the physical traits of his Silver mother. Her influence can be seen in his ability to summon rainstorms, in such instances the aura that Aeillos generates is a bright silver shine, incongruous with his darker colors. His name bears no hidden meaning or legacy, other than its originality. Like other Grays, Aeillos has a hair-trigger temper and does not hesitate to assert his authority over those who question him. He differs from other Grays in that he does not frequently use his influence on the weather to bolster his defenses. Rather, he takes the time to specialize in low-altitude flight, challenging himself over all different kinds of terrain and learning to use the land's geography to his advantage. Though easy to provoke, those he is familiar with need not fear him or his powers, and he returns that respect in kind.
