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.

Morgana is fierce in combat, using both her claws and her impressive horns to drive away would-be intruders. When she isn't engaged in battle, she likes to take it easy and stay as calm as possible; if her anger gets to a certain level, she can be nearly uncontrollable. In this state, she is a danger to all those around her, especially due to her ability to inject neurotoxin. The only hope of getting her back to normal is to be subdued by another Bleeding Moon dragon, as they seem to be the only ones who know how to bring her back without seriously injuring her.
