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.

Nimloth was one of the first dragons born into the Durelen clan. With the new clan's numbers being relatively low and them trying to expand their territory, every new addition was of vital importance and so Yavanna's pregnancy was followed with an air of joyous expectation. His hatch-day celebration is still remembered fondly by older clan-members who were there to witness and very much enjoy the happy occasion. From a young age he enjoyed the care and attention of his clanmates for whom looking after the small adorable hatchling was a novelty and, in its own way, privilege as only the most reliable and trustworthy dragons were allowed to care for youth. Although a bit spoiled and used to having his way, he's generally a goodhearted individual and tries to do what's right (and if he somehow profits from it, why all the better!). Armed with a keen mind and silver tongue he's found his calling in trading, enjoying the challenge of haggling for... well, anything really!
