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.

Sunset Sienna, or Sienna for short, is a young Sunset Dragon. She is very talkative, and has annoyed the other dragons to the point where she has to live with the eggs and hatchlings, away from the other adults. She has the role of being the hatchling and egg sitter in her clan because of this. She is very naive, ditzy, blissfully unaware, and, well, "derpy". She thinks of Soarin' Skies as a big brother, considering he is one of the only dragons in the clan who isn't annoyed by her. She has absolutely zero fear of humans, and follows them around if they are nice to her. She likes humans so much, she once followed a human back to the nearby village, but was brought back to her clan by her exasperated trainer. Even though it isn't visible, her eyes are almost always crossed. She currently has no specified mate, as most of the males are annoyed by her.
