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.

Stoic and calm, Eteocles epitomizes the traits of his race. Although he enjoys talking to the other dragons in the cave and is extremely intelligent and well-informed, he refuses to move from his position near the mouth of the cave. If one wishes to speak to him, they will have to make the effort themselves. Eteocles has a fondness for the skittish Musica, enjoying teasing her to the point where she executes her trademark flight from the conversation. She is the only one in the cave he is remotely protective of, and as such he deeply mistrusts the vampires living with her.
