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.

Sapphire Spine, or just "Spine," is a notoriously grumpy spitfire dragon; even though he was hatched and raised by human hands, he decides to spend majority of his time in isolation. He may visit his "family's" cave often, but he spends majority of his time creating a large heated-glass cavern deep in the desert, just a short flight away; he prides himself in his intricate glass sculptures that he carved into the walls and support pillars of his labyrinth. Having spent years making his desert home, Spine will guard his territory fiercely, setting up spires to ward off other dragons, especially spitfires. Only once or twice has he let his closest friends into his glass cave, all the while keeping a close eye on them and "escorting" them to the edge of his territory when they leave, only a short while later. Being overly protective and isolated, he constantly drives every dragon from his territory, teeth and claws flashing.
