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.

Carabaxas is a Bright Breasted Wyvern and the twin brother of Casynch. As a hatchling, he was the smaller of the two brothers, and was frequently bullied by the larger and stronger Casynch. As a result, there was no empathy, or any sort of positive bond between the twins, and Carabaxas spent most of his time trying to avoid his brother. But as the pair grew older (and Carabaxas stronger) it slowly became apparent that the two brothers were coming to resemble each other more and more- until a point came when it was impossible to tell them apart unless you knew the markings to look for. Much to Carabax's distress, he is often mistaken for Casynch, and like his brother, he has to spend most of his time hiding from his twin's former victims.
