Magi Dragons are, as their name suggests, primarily magic users. They rarely use physical forms of attack. They eat anything they can kill, which is almost everything. They won’t kill unprovoked except when hunting, although they may kill humans if in danger. Their strong magic makes them one of the most feared breeds of dragons.

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.

Diagnostics currently lives in a complex across from Tones Hall, where he teaches. He has taught in 16 schools and learning centers, about three-quarters of them as a visiting instructor. He likes going to different locations because not only does he get to interact with and enrich different minds, he can sightsee, discover new local ingredients for potions, and expand his palate. Diagnostics is interested in studying legal codes just as a hobby, and he loves the color purple and keeps unused dark mana in his living quarters simply because it's purple.
