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.

Kato Uchiha is a strange dragon, and not only for his breed. He's calm and reserved, although he can switch to a demon if angered. Also, he's a master of The Look. Whenever he's slightly annoyed, he'll give whoever annoyed him The Look. No one wants to see The Look. No one wants to be anywhere near The Look. Whenever The Look is directed at someone, they freeze in place, as those eyes bear into their very soul, making them remember every single little thing they have failed in through their whole life. The Look saps their will of living and reduces them to a sobbing heap of failure if it is directed at them for more than a few seconds. The only living thing immune to The Look is Arma Karma, Kato's mate. It is recommended to hide behind her if there is the smallest possibility someone's going to be the next receiver of The Look.
