Geode Dragons are closely related to Stone dragons. They are covered in a hard stone-like material as well as beautiful crystal. Their wings are entirely useless for flight, but they help attract mates. The dragons with the most brilliant and colorful crystals are more likely to mate.

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.

Colla is a very down-to-earth, reasonable sort of dragon. She has this refined, alluring sense about her; she's somebody that radiates a cool energy that seems to calm others down whenever she enters a scene. Colla is rather quiet, and, even when she does speak, her voice is low and whispery. She almost seems to grunt every word she says. And yet, somehow, she can make her mumbly, gravely voice sound legitimately commanding. Colla is exceptionally intelligent, both socially and in general. She has a way of manipulating the environment around her to set whatever mood she wants to enforce upon others. Not only can she do this through tone and dialog but also with her incredible control of Earth magic, which she will use to literally shape the area around her. Though skilled in magic, Colla is no fighter. In fact, she does very poorly when directly engaged herself. Colla is the kind of dragon that needs complete control of her surroundings, and, if not, she flounders and may even panic.
