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.

Fire's Heart is highly aggressive and a little asocial, having rejected many dragons as mates. The other dragons tend to get angry with her, especially when she snaps at their young for getting too close. Many believe she was raised this way and will stay this way forever, but others think that with a little love and affection, she will show her true self. She has turned calmer and less aggressive ever since she chose Ivy'sShadow as her mate.
