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.

Mitsumi and Rouge are feisty dragons, they are almost always fighting. They were even born fighting each other, literally. They hatched out of their egg sprawled across the floor, nipping at each other. Age didn't help this problem, as an older hatchling, one tried to push the other down in flight even though they share a body, and in result they always ended up falling to the ground twirling in a corkscrew motion and biting at each other, always to be saved by Viz or Shadow, whoever was taking care of the young at that time. Now as an adult, they have fought less, but both heads lay in opposite directions in sleep, what I have heard from Viz is that it might be a desire to obliterate the other one and become a normal dragon.
