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.

Species Delta, or Delta, was captured by humans at a young age. Far from his home, he was raised and experimented on. The humans didn't know what type of dragon he was, for they had never seen another one of his kind, so they called him Species Delta. Obviously, Delta wasnt the first dragon they've captured. During one of his tests, Delta destroyed his restrains and took out a few of the humans. He helped other dragons out of their cages, and they all escaped, luckily with their lives.

Delta returned home, but growing up with the humans, he had no dragon family. He had no idea who his parents were or even what his original name was, so he stills calls himself Delta. He has seen the other Spitfires, and they try to tell him that he is one of them, but he tells them "No, I am Species Delta."
