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.

With scales the color of night, and wings as red as blood, xXTwilightXx, as named by his fellow pack members, guards the twisting caverns of the pack's mountanious homestead. Despite his looks, he is a very outgoing and social dragon, often seen with every dragon in the pack, from Tarkie, to Leo Hydroa. Even knowing this, a human who stumbles into the pack territory will find this Sunset Dragon terrifying.
