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.

Addei is a bit hyperkinetic. As a young dragon, he was  always running and jumping around, chasing butterflies and small birds for fun. This sometimes got on the other dragons' nerves a bit, but as he was always in a good mood and ready to help, they just couldn't be mad at him.

Though his energetic behaviour scared Accalia at first, he didn't give up on his love for her, and learned to control himself. Now, when he feels the need to run and jump, he goes outside the cave system to do it, so she isn't bothered by it, and neither are the other dragons.
