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.

Luna and Yune are short-tempered and tend to be very possessive. They both fight for silly things, and it always looks like they are separated dragons in different bodies. While Luna wants to taste the prey by her own, Yune also want to taste it and is only satisfied when she ate the food, and not Luna. Lune and Yune fight for things that doesn't make since at all, but they are extremely intelligent when they think together. They won't choose any kind of male from their own species simply by looking at him, they prefer to know him fully for a long time to trust him enough to breed. Luna and Yune are mean, and ignore most of dragons they don't know well. They like being around who they know and hate to be alone.
