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.

Living in a large pride with other Sunstones, this dragon doesn't particularly stand out. He isn't the fastest, strongest, or smartest, but Garnetheat is fairly adept at using magic. He uses his power sparingly, however, only if there is no other option. As such very few of the other dragons know of his ability at all. His mother and grandmother would have liked for him to continue their family name, but his father and grandfather, who are Mageia Xenowyrms, weren't as interested in carrying on the tradition. He is quite close to his fellow Sunstone sister, Desertgleam, but doesn't see his Mageia sister, Miragewyrm, very often.
