Terrae Dragons are primarily herbivores who prefer to eat from the tops of trees. However, due to their massive size, they must rely on small, specialized scales to absorb and convert energy from the sun. Since they live in tightly-knit groups, this form of energy absorption helps preserve the forests in which these dragons reside.

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.

Mosswing is big for a male of his kind, though still smaller than the average female. His size helps him to gather more energy than most males his age, but it can prove troublesome in the confines of the cave at night. He mostly keeps to himself with the exceptions of Frida, Teaflower, and Hope, as they are all herbivores like him for the most part. On bright mornings he can be found on the plateau above the cave, back to the sun and wings spread wide to catch as much light as possible.
