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.

Lizardheart was never afraid to fling her weight around. Being a Terrae dragon, her mother taught her unique battle skills for using it. Lizardheart had always dreamed of becoming Medic, but her sister, Mintberry, discouraged her and talked about how "boring" it was so she herself could become the next Medic. Lizardheart now has extreme scorn for her sister, but still loves her because they are sisters.
