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.

Moss Hide is Ficus Bough's best friend. Even though he is a very soft-spoken dragon who will only make his opinions known when it is absolutely necessary, he has a very firm set of beliefs, and it takes a lot to sway him once he makes up his mind about something. On the other hand, this unyielding attitude makes him extremely loyal to his dragon clan, and full warning is given to any dragon hunter who threatens his friends.
