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.

zerOX is probably a mathematical genius. The reason it is only 'probably' is because her complicated proofs are so difficult to understand that anyone she tries to explain them to gets so much of a headache from all the numbers that they can't tell if any of them work. Her favorite theorem is one that somehow proves how animals form their stripes, spots, or other markings. Needless to say, it makes little sense. Fortunately, unlike her mate 60346 she is capable of giving an inquiring dragon the answer to a geometry question without frying their brains with the math, so a number of dragons ask her when they need help finding areas. Esivan the construction dragon is one of zerOX's most frequent inquirers.
