Magelight Pygmy Wyverns make their homes deep under the earth, and produce a flammable, oily secretion from the tips of their tails to make light. The substance is long-burning, and brooding mothers douse their eggs in the oil while they incubate. Hatchlings’ tails subsequently catch fire at birth after coming into contact with their burning shells. Magelights are useful to human miners, as they are docile and easily trained to alert to the presence of methane damps, caved sections of tunnel, and proximity of nearby dragons to ensure the safety of crews.

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.

Pygmy dragons are the smallest category of dragons, being on the same scale as domesticated animals. They are often found around concentrated populations of dragons, relying on their larger brethren to ward away potential predators and leave scraps. As such, the majority of a pygmy’s diet is scavenged. Due to their tiny size, pygmies do not breed with larger varieties of dragons.

Whenever human miners and other outsiders turn up, Jaylund is their guide for her family's cave. It's not because she has any traits that make her better at communication and knowledge-sharing than anyone else but because out of everyone in the family, she has the most pronounceable name. She cheerily guides the humans through the cave, pointing out dangers and good spots to stop, and they pay for the service by allowing her to poke open any of their boxed or canned comestibles. They don't know they're trading food for guidance until they find her going through their supplies.
