Ember Dragons have a great affinity for hot environments. While they themselves are not hot to the touch, their tendency to lurk amongst smoldering ashes has caused many to believe they are fire-starters. Their dully glowing markings serve many purposes: acting as a means of identification between individuals, as an important part of mating displays, and as a way of showing aggression. The long, low build of the breed makes them ungainly in flight, and the thick fleshy membranes of their wings hinder them further. As such, it is rare to see an Ember Dragon take to the air. Ember Dragons are also not particularly sociable; females tend to be defensive, whereas males are more aggressive. Once they have settled with a particular group of dragons, Ember Dragons are incredibly loyal and will defend their pack by any means possible.

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.

Ember Comet or 'Comet' is sort of an outcast at Kaoru's Cave. The first Ember Dragon present, his presence had caused quite a stir amongst the adults of the cave, as they had never been taught how to respond to his breed. Even the hatchlings sensed this and kept their distance from Comet.

Comet, however, took this well and now usually stays in the nearby volcano, checking it every day to make sure it won't erupt on the other dragons of Kaoru's Cave. Comet gets along best with the 'Fierce Dudes', the pack of Ochredrakes of Kaoru's Cave. They don't see him as any different than other dragons, and though they're not that intelligent, they're friendly and loyal to him.
