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.

Celesti Santiago has an abnormally large gem on her tail for such a young dragon. This is due to the fact that she is spoiled by her mobster father, Sunny Santiago. He checks up on her constantly, and always brings delicious gemstones when he does. Celesti tries not to wonder where he gets the money to keep her so well-supplied, but ultimately, curiosity got the best of her. Celesti found the Turpentine Dragon that was the mob's lawyer and secretly looked at her list of clients. Celesti was surprised with how extensive the network was; she also felt a bit ashamed considering how many people must suffer to satisfy her father's greed. Torn between her gem supply and doing the right thing, Celesti is considering going to the police with details on Sunny's operation.
