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.

A very chatty yet temperamental dragon, Oldbag is often seen guarding the cave from a few constant youthful pranksters that keep getting into the archives.

She isn't too fond of those younger than her by a generation or so, nor does she have the patience to deal with them. She often calls them "whippersnappers" and often regards them as trouble.

However, once someone gets her to talking, it's impossible to get her to shut up. Especially since she often goes into tangents about the past or some other subjects. While she's talking, it isn't a good idea to make her mad, otherwise she'd go into a non-stop ranting phase with some added earthquakes that Kim and the other residents have to wind up dealing with.
