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.

Valdearg is the oldest dragon in her owners cave; the first dragon and the first 'cave-born' to be stolen. Her name means "Wings of Fire", as her red wings glow and shimmer for her namesake. She's had a few children, though she has not yet been successful in finding a lifelong mate for herself. This is partially due to the fact that she'd rather be alone than with other dragons, socializing only with her human owner or with the dragons he presents to her. Despite being the first dragon in the cave, Valdearg doesn't act territorial or present the need to be the center of attention. She sometimes becomes jealous of the 'rare' dragons in the cave (mainly Vined Light and the other prizes), because they get treated like royalty while she is just another commoner in her own house. Even though she is aware that her human owner loves her very much, it stings her heart to watch the young, 'specially bred' dragons get pampered.
