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.

Ailleacht Cloiche is the daughter of a sapphire dragon and a fell dragon. Due to her mother's being a fell dragon, she is rather violent and will lash out at anyone who makes her upset. She hates being told what to do and tends to be very moody during the day. Ailleacht Cloiche also has some of the sapphire dragon friendliness because of her father. She tends to be gentle with hatchlings and smaller humans but growls at most men. Ailleacht Cloiche has been known to grow soft around small human children and is fiercely protective of her family.
