Spitfires are a desert breed of dragon. Their dull brown bodies contrast with their brilliant turquoise markings, and they only blaze brighter when these dragons fight. Spitfires are notorious for their territorial natures, and the wing-edges of most are ripped and tattered before their first year is out. Spitfires are also noteworthy for their brilliant blue fire, which is used not for hunting or fighting, but rather for making glass caves from the sand, in which the dragons can soak up the sun.

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.

Mthymos is a kind but serious dragon. She doesn't like the horseplay of hatchlings and prefers not to talk to adult dragons unless necessary. Most of her time is spent practicing her glass blowing and improving her home. She keeps an eye on the hatchlings to make sure they don't get hurt but denies it when someone catches her. On occasion, she will talk to and fool around with the other dragons, but that is quite rare. Mthymos is most comfortable around Karmazn and Fagyni. She prefers to be called Myth but doesn't protest when called something else.
