Gold-horned Tangars are a brightly colored tropical breed. They are primarily herbivores, and eat a wide variety of fruits and flowers in addition to the occasional bird. Tangars are well suited to life in the trees; their slender bodies make them light enough to be supported by thinner branches and agile enough to avoid obstacles while flying. Their brightly colored horns, found in both males and females, are used to attract mates.

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.

Taxi Cabs ferries people for fruit. Other dragons think he's odd, while some humans regard him with suspicion. He is easily bullied at home and despises spending several hours a day mucking about trying to pick some decent eats. Not long ago, he learned that humans are super picky and super productive with their groves and learned how much trouble he'd save by presenting himself as a sapient, flying cart. Though some riders have muttered that Taxi Cabs' back could use some cleaning and he should honk less, they largely acknowledge that his service is useful and often even exhilarating. He even lets them pretend they've "tamed" him.
