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.

Warbler loves fruits such as apples and pears; the sweeter or more sour, the better. He will hoard fruits, then enlist Breath of Winter's help in freezing them temporarily to store away for a later time. Warbler is chatty and vibrant, always willing to play with the other dragons, even if some of them do not want to include him. He is most active during the spring and summer seasons, but when fall and winter come around, he grows sluggish and sleeps more often.
