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.

Night's Heart prefers hunting in the dead of night instead of sunset. She hunts with Nightwatcher, her friend and long-time ally. Her night vision isn't as good as a black dragon's, but has better night vision than most dragons of her kind. Night's Heart is a scholar at heart, reading scrolls and books alike, even changing form to mingle with humans with the help of Kiranal. What masks this love of knowledge is her love of battle.
