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.

Incendi never has time to relax. She's too busy fighting. As she was the only female in her tribe of spitfires for a very long time, she feels she need to prove herself excessively. Most of the other Dragons of the Dusk Divide Dragon Keep steer clear of her because she challenges everyone to a fight on first sight. On these fights, she's been known to kill. Her personality assumes the mask of her bravado until it is no longer a mask. Her confidence is never a hindrance; she knows her limits well and adjusts for them. Some of the only dragons who dare to spar regularly with her are Bright War Blade and Phire Fatale, and she respects them.
