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.

Rainbow Sunset is a very lonely dragon. She came in the clan very willingly and did not need much convincing unlike other Sunset dragons. She loves to be in a small group and usually leads it. She has been very sad that her father is deceased and weeps when the sun is setting making a rainbow. Some clan members call her "Weeping Rainbow" for this. It angers her and she flies away, knowing they have never lost a family member.
