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.

If not swinging on branches until they break, Sierrabelle is listening to the beautiful voices of birds. She hasn't been blessed with a singing voice but likes trying to get in tune with them. Though birds sometimes get scared of her sounds and turn silent, seeing she doesn't want to hurt anyone, they continue letting her join in.

Sierrabelle is very playful and loves nuzzling little baby dragons even if they get on her nerves. They normally get even more joyful and playful, but she can control them then, by holding them with her tail.
