Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

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.

Bob always wanted to be an "architect" ever since he was a small, insignificant hatchling. Unfortunately he's a huge, somewhat clumsy dragon with about as much knowledge of structure and design as your average baby bunny rabbit. However, due to this interest, he often likes to take apart human dwellings to see how they put it together. Often there are still humans in the building who run away screaming as he prods at the wall patterns, room heights and lengths, roof structure, etc.
