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.

This dragon is the source of much confusion in the Nightfyre Caverns. When it gendered, every dragon in the Caverns swore up and down it was a male, and caretaker Raptor was distraught, as it would mess up the pretty male Sunsong to female Tinsel lineage this dragon carried should he be bred.

However, at adulthood, Sinner's Progeny suddenly became female.

Needless to say, the entire population of the Caverns is in a state of utter confusion regarding this dragon's unexpected "coming out", and she isn't giving up any details about how her gender mysteriously changed.
