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.

Haruka's name means "Spring Flower" in Japanese, while Haruna's name means "Spring Vegetables" in Japanese. They were raised by their fathers Rai and Rei, and their mothers  and Mina and Miya. Although they share a body, they are very different indeed. Haruka is a free spirit and enjoys nothing more than lazing about in a field of flowers, Haruna on the other hand is a very hard worker and enjoys helping Remy plow her fields. Haruka is mated to Yuuta and Haruna to Yuuto. The girls are a little bit younger than the boys, and when they were hatchlings they had a major crush on Yuuta and Yuuto. Once the girls grew up, the boys returned their affection, and soon they were courting. They are all so glad to have found their soul mates, they love each other so much, and always will.
