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.

Flying Space Goat was punted into space by his mother after he stole the eggs she was watching over and ate them. He met some space goats on a nearby planet and was crowned King Space Goat, but he ate them because he was hungry and did not enjoy the local diet of brussel sprouts. In doing so he absorbed their mystical powers of creating noxious gas clouds in replacement of an animal's regular waste-releasing system. FGS came back to his home planet to give his mother a taste of his new weapon and is still in search of her.
