Sapphire Dragons were so named for their brilliant blue-green color, which is reminiscent of the gemstone. This breed was historically hunted for their scales; even long after, they remain distrustful of humans. Normally a Sapphire is not very aggressive, but they will defend themselves vigorously if under attack. Their diet consists mainly of fruit, with smaller portions of large insects and other invertebrates. Males woo females with vocalizations similar to bird songs. Sapphire Dragons are very loyal to their mates, and it is not unusual that they pair for life.

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.

Oiy is the Top Sixth (If You Don't Include Air-Element Dragons or Spirits) Flying Ace of the Motley Coast, and he happily takes on any job from the council that involves flight. Despite his insistence, the council sometimes will give a desired job to someone else whom he feels is equally or even less qualified. His rule-following sense is stronger than most other considerations, including personal safety. He lectured a traveling desipis-xenowyrm pair on the correct order of steps in the visiting procedure, and to the shock of everyone around, not only did he survive completely intact, the two dragons followed the rules to the letter while wearing toothy sneers.
