Bright-Breasted Wyverns are a breed of dragon easily recognized by their bright red markings. They are a small breed, only the size of a full-grown man. However, they have developed poisonous barbs on their feet to make up for their size. Their coloration is used to warn off potential predators of the danger, and is also used to attract mates. They are very social, and can often be seen preening in large groups.

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.

Mountain's Sunset is a very cheery and talkative she-dragon. She is always found with some dragon or another, and loves to play with little ones. She is very close to Salmon Storm and Hasty Bolt, as she often enjoys spending time with them more than any other dragons. She loves her owner with all her heart and is a very graceful flyer. Though she never searches for attention, Mountain's Sunset often gets it, yet a part of her does not care in the slightest. She has an unusually long tail, one that often leads to her tripping herself constantly.
