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.

In the dead of night, a large, monstrous figure arises into the air, large wings spread out, fanning the cool night air. When the night ends, the beast can be seen slinking back to the castle's belly, disappearing once more, waiting for the nights return. The spots on Zela's body are an even crimson, nothing particularly dark, but not exactly candy-red either. She lives deep within the recesses of the castle's dungeons, in a dank and frigid cavern. Due to her large size, many are frightened by her and have chosen not to associate with her in the slightest. However, the Castle Master has taken a particular liking to the Bleeding Moon, and has often been seen making the long descent down. However, Zela is often wary around the human female, as she is very much aware of what goes down beneath the surface of their stony fortress.
