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.

Atonus Nixeu is a seclusive dragon, preferring to live alone in a cave on the magma flats. She isn't one to be caught out in a crowd, and often doesn't know what to say when others talk to her. She enjoys moonlight walks and usually spends a great deal of time exploring the magma flats around her cave. She sticks to the shadows when she is forced out of her cave during the day, where her beautiful markings dispel the darkness around her. As a hatchling, she sat out of most activities on purpose, feeling the need to be alone. She is very creative, and can reason her way out of a bad situation in a snap. Gryphonluver counts her as one of the most special dragons she has ever raised.
