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.

A vicious, brooding female, this wyvern was hatched and raised by members of a well known cult. While few outside the group are aware of what goes on within the circles of that dark membership, those few members who have managed to flee the organization with their lives intact tell hair raising tales of bloody sacrifices and brutal rituals--and of this wyvern. Fiercely loyal to the group that reared her, she is used by the cult's leader to fatally poison any who don't match the cult's standards of pious behavior--a habit that has earned her her name.
