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.

Blue Fire is a very solitary dragon because the other dragons tend to stay away from him because of his bad temper. He lives on a small patch of desert-like land. For some reason, he only shows a soft spot for White Cloud of Blue Sky. He especially dislikes Kano Shima and Aquario of the Water because Kano is White Cloud's best friend and Aquario is her mate. Sometimes Blue Fire burns cacti and other plants to help let out some of his frustration. Lately he's noticed that Equina of the Horse Dragons tries to get as close as she can to him. Now he is starting to like her a little more than White Cloud.
