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.

Daitaro's name means "Great First Son", while Daijiro's name means "Great Second Son" in Japanese. They are the firstborn sons of Rai, Rei, Mina, and Miya. They are both very adventurous and love to fly, due to their heavy build, they can't fly very fast, but they do enjoy flying high. Flying over the water is Daitaro's favorite pastime, while flying over the forests is Daijiro's favorite pastime. This is because they can see all kinds of strange and interesting creatures. While they may be very similar, both dragons HATE it when people confuse them for one another. They are both very unique, and they fight every day to prove it. For example, Daitaro is an excellent singer, while Daijiro is a great poet, and often composes the songs that his twin sings. They are both childhood friends with Toya and Taya, and when they all grew up, they became mates. Daitaro with Toya, and Daijiro with Taya. They all love each other so much, and they always will.
