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.

Tropic's Secrets Within (nicknamed "Secrets") is mate to another bright-breasted wyvern in his owner's herd named Faragard. The two of them live in a forest not too far from the cave their herd lives in, taking shelter inside an old tree with a huge vertical slice in its side, probably the outcome of a lightning strike. The tree inside is hollow, and has been turned into a comfortable living space with grass bedding and smoothed walls. Though Faragard looks more to challenging herself against her limits (in fun ways), Secrets is content with sitting in large branches and watching the wildlife. He rarely talks and is more of the "quiet observer" sitting on the sidelines.
