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.

ROTATOR, who doesn't do much rotating, was named because her humans thought it would be "mighty cute" for her name to be a palindrome. The humans happen to be called Otto, Eve, and Hannah. ROTATOR actually has mild aibohphobia, sometimes thinking the letters in the word or phrase have a bad "taste" when they spell that way, and she avoids using her own name when those thoughts creep into her mind.
