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.

Despite being a battle-hardened, scarred little female, Fluff has a much softer side to her otherwise gruff and prickly personality. She has always taken much joy out of her natural tendency for sculpting tough glass structures, and has taken that a step further: creating delicate greenhouses lining the edge of the forest, each given freely to whomever lays claim on it. Her own nest had been blasted onto the side of the mountain, a precarious glass tower resembling whorls of smoke, which she protects viciously. Even her own mate has been knocked away from it at times.

Her largest project yet is still unfinished—a massive dome, intended to be a comfortable respite for the weyr's more tropical dragons, a place in which they can plant their various unusual trees and introduce small, foreign lifeforms for their own speculation and enjoyment.

As a powerful champion of the weyr, Fluff spends much time sparring with her mate when she desires a 'rest'.
