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.

Kuzuri is a loving and patient dragon and quite literally the polar opposite of Doku. She is very responsible and can always be trusted to finish whatever she is assigned to do. She is also an expert in multi-tasking although it origins from her inability to say "No" when asked to help someone which most of the time ends up with her juggling lots of things to do. She is also unique even among her breed as she is incapable of producing poison but producing antidote which can even cure the most potent poison instead.
