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.

Nighna has a habit of wandering around at night. She will sometimes stray a little too far from the cave, get lost, and end up sleeping in a totally new place until another dragon from the cave finds her and brings her back. Often, this sort of thing happens, so it isn't unusual for a farmer in the nearby village to find her sleeping in their pastures. They know she won't eat their animals because she only eats wild ones. She is very curious and loves to explore, which is the reason for most of her wanderings.
