Split Dragons use their sharp teeth and wings to hunt large animals and rarely eat plants. They are intelligent dragons who enjoy mental challenges, preferably alone; Split Dragons are normally solitary except during mating season. When mating, many dragons come together in a group to raise their eggs and hatchlings. These groups tend to be very noisy—reminiscent of a thunderstorm—and last only until the hatchlings are capable of surviving on their own.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Felix and Fred are the intellectuals amongst Dragon Writer's friends, and have been ever since he made the mistake of mentioning the old adage, "two heads are better than one," in their presence. They make a point of learning whatever there is to know, and use that knowledge to make life easier for members of the Draconic Revolution, whose quest it is to impose an equal human-dragon government-no matter how much Dragon Writer grumbles about their chances. They split their time between helping Rachel, helping fog, and simply dealing with the day to day problems that plague a Draconic Revolution-although they refuse to mention exactly what those problems are.

Though usually getting along, Fred and Felix have been known to occasionally argue, with rather comic results-particularly when arguing over who gets the last piece of food. The fact that it goes to the same stomach appears to be rather lost on them.
