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.

OypoD uses magic to seal songs into little glass pods, each signed with a motif that some compare to an apple leaf and others insist looks like an eye. Her hoard of music has grown large over the years as she continually records new tunes on glass. She acts as a DJ for kQED4, the green dragon, filling unused time on his mana-wave radio system with music from her collection. The most-played songs, however, are the short and obnoxiously-catchy ones that introduce certain programs. When people ask, she will make copies—signed, of course—so that she can share music more broadly. These have travelled farther than OypoD's name, so they are known by the shape of the glass and the signature—that is, as "Apple-Eye Pods".
