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.

Eternal Twilight of Immortality is a gracious, wise dragoness. She is impeccable with her manners at any gathering, and will gently remind the slobbier dragons of their manners as well. She often is found on a cave ledge in twilight, brooding about the mysteries of life, which she is apt to share with others if they so should disturb her musings. Also, Violet Glow of Sunset is Eternal Night of Immortality's spirit twin sister, so they can guess each other's thoughts and current activities with eerie, uncanny precision.
