Bleeding Moon Dragons are mostly nocturnal creatures. When outside in the sun, the small red spatters on their back grow and spread, making the dragons appear to “bleed.” It is said that the darker the shade of red, the more aggressive the dragon. Their tail barbs contain a powerful neuro-toxin which they use to subdue their prey. They are solitary creatures except when mating, preferring to dwell in the caves in mountains or other high places. Their large wingspan makes them fast flyers as well as fast runners, but they prefer to glide instead. Males are very competitive and will try almost everything to impress females, who will choose their mates based on speed and performance. Juveniles tend to form bachelor groups once fledged.

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.

Pny usually sticks with the guys for most of the day, though he'll occasionally leave the group for alone time. Normally peaceful with other species, he saves his aggression for hunting and eating creatures but will otherwise walk away from a fight. The exception is when he sees the land undergo large-scale change by humans: deforestation, fires, mountaintop removal, et cetera. He is usually able gather his band and just glare at the perpetrators until they leave, but of course Pny is very well able to fight them if they don't get the hint or refuse to go away.
