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.

Nearly everything about Thief-of-Faces is shrouded in rumour. He is sometimes known as "Snuffer" due to his love of candles—he eats them, snuffing them out. He is almost always in disguise as another dragon, creating perfect masks using the faces of his victims and a great deal of illusion magic to fill in the holes, and he changes faces as often as a storm dragon changes the weather. Thief-of-Faces can handily win a fight with another dragon, and he uses magic liberally if his natural agility and strength don't suffice. It is said that he has a number of underlings throughout Galsreim, but how many there are is impossible to tell since they also wear disguises made of stolen faces. They're not all hated; they make excellent spies and informants, though all, like their master, have a taste for candles. If one spots a dragon devouring lit candles, one can assume that before them is the inscrutable and extremely dangerous Thief-of-Faces, or (more likely) one of his followers.
