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.

Mimi asola had always wished she could fly, trying many things to make it even happen (including letting magi dragons try to give her wings with their magic). But Mimi has a very unique talent: she can jump very high. So high that some dragons who first saw her thought that she really was flying. Mimi asola's very strong legs make her very dangerous in battle because one kick might knock out a black dragon. Mimi asola luckily never provokes any fights. Still, her unique talent scares a lot of dragons because her body is very massive being a Terrae dragon. Whenever she lands the earth shakes making an impression of an earthquake. Mimi herself is humble, calm, patient, kind, funny, polite and caring but she can also be easily depressed and too quiet. She admires skywing dragons and is most of the time spotted near them because she admires their flying skills. Mimi shares close bonds with Kaede firestrong, chi gold star, Yue silverflight and adka.
