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.

Flashthroat is one of Phoenix's dragons. Haughty, snobby and with an extreme Jehova-complex attitude about herself, Flashthroat is one of the most showy dragons in Phoenix's cave and considers herself at the top. She loves flirting with other male dragons and teasing them, although her only true mate is Pythonchest, a dragon of her kind, with a personality much like hers. Flashthroat is always arguing, or trying to argue, with Vyra and Frillpounce over who is the most attractive, although Frillpounce and Vyra are smart enough to recognize Flashthroat's shallowness and usually leave her out of the debates.
