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.

Borboleto is the self appointed Head of Theater in the Rainbow cave. Ever since he became best friends with the moonstone dragon Moontower, the cave's celebrity vocalist, he fell in love with the excitement and intensity that a crowd brings. He started off gathering all the hatchlings in the cave to put together small plays, such as "Our Cave," "My Fair Dragoness," and "The Music Dragon." He now has a very eclectic group of talented dragons, and creatures from all over come to enjoy their wonderful performances. Borboleto is quite pleased with his accomplishments, and loves trading stories with Moontower when he returns from his tours.
