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.

L'Muro may be quiet, like most Spotted Greenwings, but he is certainly not shy. He is a trusted advisor of L'Iyserod, partly because of how long the two have known each other and partly because his mind works in ways that other dragon's just do not. L'Muro seems to understand the motives of others better than he understands his own. He is often found sleeping, sometimes even at night, in hopes that he will dream something that will help him understand more about the world around him.

Despite his high status on the scroll, L'Muro lacks many social skills that seem to come naturally to others. He will sometimes stop and watch other dragons with no word of explanation or apology, and he doesn't understand jokes even after they have been explained to him. Still, L'Muro remains the go-to dragon for relationship troubles, as he is bound to know every perspective involved by heart.
