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.

Hatching shortly before the retirement of the Anti-Hunter Program, Striker Eureka was trained. Striker Eureka is a strong dragon currently waging combat against the hunters. The Pebble division of the Dragon Cave Defense Corps invested a reported 4,167 stones into the creation of Striker to create one of the many powerful dragons in the world. Striker may be a warrior but deep inside his stony heart he is yearning for peace among the hunters and dragons. He is always thinking about the safety of others before his and sometimes gets into trouble for that kind of attitude.
