Stone Dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

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.

Halldur, the brains of the Three Terrors, coming up with plots and schemes and ways to escape the cave for a day. All the three friends are smart but they couldn't hope to come up with the clever ways of escaping that he does. Although he is part of the Terrors he isn't completely like them on every level, he has found himself completely and utterly stuck on one girl. Not like the two girls in his group, bringing in male after male dragon, using them for toys then throwing them out because they weren't new after that. No, just one girl for him and that's the way it would always be. Zenobiia or Zeno, the first beautiful sunrise dragon of the clan. The one closest to his age of the four hatchlings but she had chosen not to play in Venn's and Lia's games. He respected that and often watches her while she plays with the little hatchlings, waiting for her to finish and come sit with him. The first real couple of the clan, Zeno and Halldur.
