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.

Shmoo was originally named Tangaagim, and was once as intimidating as a bear. Gruff and domineering, she made for unpleasant company. Over time, however, she began laying eggs and slowly changed with each one's hatching. The variety of children she was having warmed her heart. While she doesn't get to see many of them, the knowledge of life she's responsible for creating was enough to let her drop her guard. She's now a maternal creature with a surprisingly playful side.
