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.

Sapphire-Blue Sapphire is a serious individual who nonetheless has a noted fondness for jokes and redundancy. As a dragon who spent many, many years traveling and doing unpleasant jobs for money and food, it's understandable that there are many individuals after him, and of course there are the handful of humans who just wish to get their hands on his hide. Faced with danger, he's remarkably calm to the point of lethargy. He simply uses all manner of magic, traps, and tricks to evade his enemies. Some have died in their attempts to kill him; most, however, died simply because he stayed out of their grasp long enough and waited out their lives.
