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.

Vanadonyx gets his name from Vanadinite, a reddish mineral—one whose tint best matches most of the glass he makes. He seems able to tolerate higher levels of heat; some lenses that his mother has thrown out due to the sunburns they cause, he has collected to enjoy the heat they bring in increasing the sun's rays. The pranksters of the cave, such as Polo or Karbyn, have occasionally tried to test whether his warmed scales will catch something alight while he basks in the sun.
