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.

Hiromi's name means "Abundant Beauty" in Japanese, and Hitomi's name means "Pupil of the eye" in Japanese since she has such gorgeous ruby eyes. They were raised by Kiyomi and Kentaro, and love being a part of the largest family in the valley. Hiromi likes to gossip and hang out with friends, while Hitomi prefers to enjoy nature. They thought that they might never finds mates, since there were no other two-headed dragons in the valley. And then Hiroshi and Hitoshi came into the valley. When the girls met the boys they just fell in love, Hiromi with Hiroshi, and Hitomi with Hitoshi. They began courting, and then they became mates. They love their mates, and are so happy to be with their mates, and with each other.
