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.

There are good things and bad things about Duskrio. The good things are that he's kind, smart, funny, fast, and strong. The bad things are that he likes to participate in battles. This is a bad thing because he's the one that often starts a war between his cave and another. That's rather unfortunate, but the war won't last long with him. He has learned the art of working metals from watching humans and makes himself and the other dragons armor. That's a good thing. Duskrio is the first blacksmith dragon in history. He uses his fire and shapes weapons as well for the dragons to carry in their talons. Duskrio may have some flaws to him, but without him, his cave would have never made those advances or been the same.
