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.

Canary only reacts to his self-chosen nickname "Medical Log". No other member of the clan knows why, but Canary one day flew into the Healing Caves, announced his new name and has stayed ever since. He was small enough not to get underfoot so the Whites came to simply accept his presence without making a fuss about it. "Medical Log" usually stays close to Pax or the shiftleader on duty and takes notice of everything that is going on around him. His high intelligence and almost flawless memory have made him an invaluable aid to the leading healers and they rely more on his abilities to recall past case histories each day.
