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.

BrainTeaser is the brainiac of the owner's group. He likes grouping the owner's other dragons together and counting them constantly to make sure that they are all there. In other words, he is trying to protect them even though that is SillverShield's job. BrainTeaser demands attention and mates lots of females from the owner's group, usually not successful because he is always horsing around. The owner's dragons just hope that he mellows with age.
