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.

Pasarela Azul doesn't really look like a friendly dragon. Every once in a while, when she's bored, she will crash through a Sand Dune and just before the sand collapses, she uses her blue crystallizing fire to create a hidden cave. The local town that rests by her cave sometimes sees Pasarela Azul doing this. To them it looks like she made a gateway to another realm when she arises from the dunes. That's why they called her Gateway Blue.
