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.

A highly paranoid creature, this female can often be seen scooting around a series of abandoned stone walls in her desert home, restless and with eyes darting everywhere. Those who politely inquire as to what she is doing receive the none-too-understandable answers that "THE TITAN DRAGONS ARE COMING" and that "THE WALLS MUST NOT BE BREACHED" and that "THE JAEGER BOY IS OUR ONLY HOPE." After blinking in confusion a few times the questioning dragon usually backs slowly away, leaving the vigilant Sunstone to continue her defense unmolested.
