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.

It seems that every Two-Headed Dragon living with the clan has something strange or peculiar about them. Felix and Felicis are no exception. While Felix is a normal dragon, mischievous at times, and a happy-go-lucky, laid back guy, Felicis had been cursed with being mute. Unable to convey his messages to others, Felicis simply looks into his counterpart's eyes and Felix can tell what he is thinking, and can then tell it to those around them. Felix is in love with Sanii, but the other head is not, so they are forced to work around differences—all Felix wants to do is be with his mate, but Felicis wants to spread his wings and take to the vast vault of sky overhead.
