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.

Erasika puts her whole spirit into nature, her home. She eats plants only when she's starving. Her clan doesn't understand why, but it is said that she was born with the element of nature within. And by far, Erasika knows the best about plants in her clan. She talks about running with the wind and singing with the river. She says that the world is the One, and it can only hold great treasures that only few can access. To Erasika, the "One" is the spirit of everything, something or someone that holds many things inside it. Erasika is gentle with everything and everyone, and she rarely makes mistakes due to her grace. She does not believe in pure evil or true death; she thinks that all creatures have both good and evil inside them, and that death is never true.
