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.

L'Celes is a born hunter, often found hunting game for the thrill of it even after her cavemates' appetites have been filled. Though her size puts her at a disadvantage when she targets larger animals, L'Celes uses her barbed claws to repeatedly scratch and rake against her target's back before flying out of range and eventually running it down from exhaustion. Despite this inherent wildness, no one questions her loving devotion as a mother. It is said that, when her one-time mate, Sysk, killed their child as a result of his violent temper, L'Celes injured him so badly that he nearly lost the use of his left eye and has never completely recovered it to this day.
