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.

Berdus is a terrae dragon that was recruited into the clan as an egg. He is a brave dragon with a slight boastfulness. Although not as brave as his best friend Drekkus, his strength is a force to be reckoned with. He and Drekkus enjoy daily wrestling matches as Drekkus does not accept the fact that Berdus is stronger than him. He and Drekkus will even spend an entire day wrestling each other while their other best friend Lupanus happily crafts a stone or mud figurine depicting the two wrestlers. He respects anyone in the clan and the whole clan respects him back.
