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.

Longtail is a mutt and proud. She comes from an extremely varied family, so her lineage is about as impure as it can get. This in turn has led to her near exile from Silvre's flock, as the members place a high value on pure lineage. Despite being excluded from nearly everything, Longtail remains a strong character, well known for her snark and attitude. She respects no one's authority and follows no one's rules but her own. She remains good friends with dragons outside of her flock, but rarely associates with those inside of it, with a few notable exceptions like her best friend Whiteheart and her mate, Greensong. She holds a high disdain for her own kind because of the way they treat her, but respects other dragons. She also has a explosive temper- she is extremely quick to anger and slow to forgive, quite a volatile combination. But despite her tough exterior, she has a good heart.
