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.

Ren'ga experienced a lifechanging event when she happened to stumble across a group of children who lived in the village near her forest. The children had picked handfuls of leaves, not to eat, but to use as whistles to imitate the sounds of insects and even play a few musical notes. Ren'ga was absolutely fascinated by this odd use for leaves and set about trying to find leaves that she could use to make the same sounds. Whenever she's finished with hunting for her current meal, Ren'ga will pick a leaf from a nearby tree and see if she can create the same buzzy tunes she witnessed. The leaves that she can get some sort of noise of she brings back to her living cavern stash. So far she hasn't had much success, but that just makes her more determined to find new leaves she's never seen before to try making music with. So long as there's still more to learn, she will never be bored of this hobby.
