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.

Nepeta is fun-loving and very friendly to anyone she comes in contact with. She is also a masterful hunter, using her toxins to paralyze small prey, finishing them with a hard bite to the neck. She seems to live and breathe the hunt and will make joyous yips and squeals when she leaves the cave for the day. She likes to play with Equius Zahhak, who is a protector of sorts; he shields her from other dragons that wish to harm her, which are very few and far between. Nepeta seems to think Equius is overly protective, but she is very fond of the Waverunner. Nepeta is very interested in the relationships of other dragons, and will usually observe them from afar, rather than directly confront the dragons she feels should be together.
