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.

Percell, in all her beauty and charm, is a giant glutton. She consumes most of the food in the Crystal Clan, usually going for the live mice and rabbits that some dragons don't find appetizing. Percell loves sunbathing and chatting with the other dragons, but her natural shy nature prevent her from holding a long conversations. If a butterfly goes by, the desire to follow it or eat it will cause her to disappear. After returning from her little hunts, Percell will make small barely audible chirp that signifies that her outing was successful.
