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.

Because of her Bright Breast, Grigoletta has always been noticeable everywhere she goes. Sadly, she doesn't like the attention very much and she can only feel good with fellow Bright-Breasted Wyverns.

She likes lying around on green tree branches and attracting various animals with her red breast. They usually think it is a fruit, but get scared by the dragon and run. She usually makes them run herself though, moving very quickly or shouting out a roar.
