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.

Roi Danton is a flamboyant dandy. He prances around, flirts with the ladies, and has his own personal bodyguard to protect him from the dangers of the world. When the stress gets too much for him he calls for a Black Tea, so the scent can calm his nerves.

He almost always acts like an effeminate fob, but underneath all that hides a completely different dragon. Roi is indeed well-trained in combat, espionage, and diplomacy, and is more than capable to care of himself. He was in fact born a Guardian dragon and has all the instincts that go with it as well as the training during his hatchling years. Only when he was fully grown did he feel the need to distance himself from his overwhelming father and all the expectations, so he searched out Delirium and asked the Magi dragoness to change his breed. Now in the body of a harmless Wyvern, widely known under his new name, he can do spywork for the clan and at the same time get on his father's nerves without Rhodan ever being the wiser.
