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.

Rosie is an incredibly vain dragon. Proud of her bright and flashy coloring, Rosie spends her time flirting, or hunting for beautiful and shiny objects with which to adorn herself with. In times of war, the allies are afraid for themselves just as much as their enemies. Rosie, clumsy as she is, seems to be a danger to everyone other then herself. Oftentimes, she will find herself in disastrous situations that ought to have killed everyone, including herself, and yet all survive with scratches and bruises while she remains entirely untouched. Thanks to her incredible talent of clumsiness, Rosie is banned from 23 locations inside the clan caves, including the archives, the kitchens, the storage rooms, and the hatchery.
