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.

"The cheese is wounded," a mysterious voice whispers from the shadows. "It is wounded, and it is suffering."

Dragons who transverse a particular section of a lonely road in the forest may come upon a huge dragon in the middle of the night. He can usually be found near the grove of rocks where he lives, deep in the forest. But on every full moon, he makes his way to the path and stands in the center of it, stopping anyone who comes by. While travelers marvel at his beautiful, silky blue scales and his blood-red horns, he tells them strange tales of a cheese being wounded. How exactly a cheese could even be injured they can never figure out, but they stay and listen, as they don't want to offend the fearsome dragon. When he finally finishes, he gives them a little jar of dust he says comes from the "wounded cheese", leaving them to wonder about what he means. But some have a theory: the "cheese" is really the moon, and this dragon has mistaken the craters upon the moon to be scars.
