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.

Rebek is very feisty. He normally gets mad if anyone comes close to Katherine, his beloved opposite. He refused to let anyone see her, but somehow a dragon named Treetop managed to get through. So did a young coastal immigrant named Shell. Rebek warmed up to them quickly, and soon they became the best of friends. However, Katherine still holds a place in his heart, and now he has three other dragons to fight with for her affections.
