Neotropical Dragons are a breed that originate in rainforests. They are fun-loving and enjoy lounging on tree branches, eating whatever fruit they find. They are also often found sunning themselves on rocks, using their large wings to soak up the rays. In the summer, males compete for mates by showing off their striped wings and gliding in spirals down the tree trunks. It is said that the larger the wings, the more likely the male will attract a suitable mate.

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.

Ustila is fascinated by events past present and future.  She is equally happy studying history, hearing stories about it, or sitting back to watch it unfold as it happens.  To her, everything that has ever happened forms one epic story, stretching out to infinity in either direction, and she sits with rapt attention, eagerly waiting for the next chapter to unfold. In private life, Ustila can seem strangely impassive, as if she doesn't care what happens on a more personal level.  In fact, she does care, but is accustomed to thinking of things on a much larger scale, so the significance of relatively small events is diminished.  As a result, she is very understanding and quick to forgive, a quality for which her mate, Calos, is most grateful.
