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.

Warrior of Poison is responsible of guarding the camp entrance. She doesn't mind the lack of sleep; in fact, she thrives on it. It gives her a challenge, and the only thing she loves more than that is to overcome the challenge. "Poison" just sits near the entrance of the camp, all day and all night, usually carving a stick or climbing a tree, pretending enemies were near. Her sister, Rainbow of the Forest, sits near by, also guarding the camp.
