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.

An impatient and short-tempered dragon, Atlas functions as the lead Ember of her two "sisters", Prometheus and Epimetheus. From the moment she hatched she was pushy and bossy, aggravating her caretaker and dominating the other hatchlings. Now that she's an adult she's not much different.

Atlas is a natural leader. Unfortunately, she is an aggressive, ambitious leader. Not many can look her in the eye for too long; her gaze is enough to make Avatars of Destruction cower. Only the biggest Brute Dragons dare to engage her in a fight; others are simply stupid. This sense of empowerment over other dragons has made Atlas quite arrogant, to the point that she challenges the cave leader, Virtus. Her attempts to overthrow him are futile, however.

Not only is she arrogant, but she is also egotistical. Atlas sees every dragon as weak compared to her. The only ones she considers to have a fleck of power are those who are brave or large enough to stand up to her.
