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.

Her name means "Dark Night" in Japanese. She is one of Kentaro and Kiyomi's many daughters, and she was raised alongside her sister Iyasu. They are best friends and love each other with all their hearts, even though they are completely different. Iyasu is completely loving towards everyone, and is a very bright and cheerful dragon; while An'ya is rather mistrustful and doesn't open her heart up easily. She is not particularly sociable, and has a feisty temper. But she is very loyal to her family, and the other dragons of the valley. She likes to hang out around the volcano, loves to gaze at the stars, and loves to sing, even though she can't carry a tune in a bucket. She met Kasei around the volcano, and it was love at first sight. After a wonderful courtship, they became mates. Their love for each other burns bright and true; and they look forward to loving each other, every moment, of every day, for the rest of their lives.
