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.

At Purefire Academy, the ability to trace one's ancestors back a dozen generations is considered far more important than magical talent, especially among the academy's leaders. Of the three leaders, Deros Initium is the one who follows Purefire Academy's rules and regulations with the greatest rigidity. He has the highest standards, rejecting dragons that the other two would have accepted without hesitation. When it comes to enforcing rules, Deros shows no mercy, and even the teachers are often cowed by his lectures. Behind all of his seemingly unshakable certainty, though, Deros is deeply insecure. All of his claims of an illustrious heritage are mere lies, and he knows he'd be expelled in an instant if the truth ever came to light, so he makes sure there's no reason for anyone to go prying into his past.
