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.

Thunder, much like her name, likes her voice to be heard at any meeting. When she's especially mad, the burst of noise she'll create sounds like a thunderclap. Despite her more volatile nature, she's a very thorough dragon, and sticks firmly to her ideals.
