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.

Green Feathers is a very spiritual and noble dragon. He spends a lot of time away from the rest of the flock, roaming the mountainside, trying to preserve the sparse trees that grow on its slopes. Before he joined the flock, the mountain was bare and rocky. Then Green Feathers started to plant and grow trees on the lower slopes, and now he's developed a small forest. He is very peaceful, only turning to violence as a last resort, and loves the feel of wind in his face.
