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.

Electric sparks flew across the black sky when a dark figure flew closer. Ketu watched as it landed before her and dropped an egg into her hands. The lightning flashed across the dragon's scales as she growled with thundering voice: "Thur Triada". The girl watched as the huge wings opened up and the dragon flew away into the night, leaving behind a distant sound of thunder. She looked at the egg. It was green, nothing like she had seen before. Thur Triada meant 'The fortress of storms' in the Old Language, so much she knew from the dragon's tales. She put her ear near the scratched shell and listened, a weak sound came from it. It was alive, yet it needed help! She took the egg to a red dragon. As soon as the red's hot breath touched the shell, it cracked, making a small hole into it. A little nose stuck out. First time, into the new world. The green hatchling looked nothing LIKE a rebelling sea, fort or storm at all, but the name stayed.
