Spotted Greenwings are relatively small nocturnal dragons. Easily recognizable by the fleshy appendages growing off of their head and rump, they are most commonly seen in forests at night, leaping and soaring from tree to tree. While generally social, spotted greenwings are very quiet and rarely make any sort of vocalization. Their bodies are unusually warm to the touch, though they are unable to breathe fire. Greenwings are voracious feeders and will consume nearly any living thing that they can fit in their mouths.

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.

Brian has horrible luck. The worst any dragon has ever seen. His attempts to hunt deer result in him getting bucked in the head, if he attempts to set traps, he's usually the catch of the day, and any attempts to make nice with any other dragon results in some form of serious embarrassment. Even a completely fool-proof plan could be unraveled by Brian's horrible luck. As such, he's avoided by every dragon in the cave and has no friends.
