Sunstone Dragons are named after the orb on their tails, which resembles the gem of the same name. Their social structure resembles a lion pride, with one dominant male and several females banded together with their young. They prefer arid climates where they can blend in and dig for minerals and gemstones that they not only collect, but eat. The more gems they consume, the larger their tail stone grows. They are an aggressive breed; it is not uncommon to see two males battling for mates and territory.

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.

Teneille likes to do nothing more than lie around in the sunshine on a breezy day, ignoring the incessant barks of the noisy boy they call leader. He might become angry and try to punish her for her insolence, but she can change his mind or change the subject without him noticing and he'll forget what he was upset about, but it's almost cruel how easy it is, so Teneille usually just acts chastened until she's adequately punished.
