Sunset Dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset Dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

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.

Despite Amser's insistence, Gorwel refuses to have anything to do with the politics that run among the clans. He turns up to few if any of the high society galas, and works as a 'lowly' hunter during the day, a physical and demanding job that the aristocrats so look down on, preferring to have occupations that do not involve them leaving the cave. Gorwel barely cares about their opinions, knowing there is more to hunting then blundering through bushes after prey, and his ability to resist irritation is too great annoyance among the upper class. Amser frequently has to go through immense teasing about this, but she is content to put up with the nagging, knowing that she should accept whatever her partner's occupation is. Still, she wishes that Gorwel would spend more time with her and living life in the same way, but she cannot deny that he is much happier as it is, although she does object when Gorwel brings his colleagues home while she is trying to host a tea party.
