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.

Lun'arax hates people calling him by his full name, and insists (often violently) that people call him by his nickname. He is quite the flighty dragon- much like the rest of his kind- and often spends long periods of time away from Tariss' Cave.

Occasionally, Lun can be found staring eerily into space, and cannot be distracted. He claims to have a link to an alternate universe, in which he occasionally views the life of Lun the Egg, and his adventures with a human named Seth.
