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.

Behold, seeker of the dragon lore, Aeri gena of the Bright-breasted Wyverns. Her name means "air-born" in Latin. For some reason she was alone, when she was first seen, although she was not even fully grown. As these dragons usually live in groups, the researchers tried to find out what had happened to hers. The simple, but sad explanation was that she obviously had been lost when the group had moved on. It is possibly also the reason for the fact that she did not quite reach the height of a fully-grown human. Her chirping, birdlike courting call was first answered by a White dragon. Although the egg took after her, she abandoned it. Perhaps she was just too young. In the next mating season she found a male of her own breed. The mating was successful and they both stayed around the egg.

She now is the constant mate of a Bright-breasted Wyvern known as Noeck.
