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.

Apollo Nexus considers himself the 'normal one' of his kind in the clan- he does not engage in dangerous experiments or socially repulsive behaviors, but instead strives to contribute to the clan with his unique traits. Nexus, in the spirit of his nature, plays a double role as both a support unit for the warriors and a skilled hunter in his own. In battle, Nexus uses his two heads to his advantage- one head may attack as the other serves as a lookout, or both may serve as lookouts for a group of warriors. Nexus' heads have also learned how to coordinate their attacks to the point where they have both the synchronicity of one dragon and the advantages of two; they use this skill to bring down large prey for feasts, famine or storage for hard times. Nexus wishes only to restore the lost honor of his species in the clan, and perhaps in the future settle down with a mate.
