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.

Drache and Drago, with a history longer than they can remember, are very old dragons, and very senile. Drago normally seems kind and motherly (and happens to be gay), but is no better than his brother. Drache, unable to breathe fire, takes to stealing cigars from humans that he finds. He is fairly laid back and easy going when it comes to his brother's mad obsession over eggs and hatchlings, but when it comes to any sort of female dragon, he promptly knocks his brother out and seduces the female in question. As he has many eggs that his brother doesn't know about (abandoned, at that, as he leaves any eggs with the mother), he loves sleeping with any single-headed dragon, as he is sterile with them.

They are unable to fly, due to their wings being savaged by the many wars and fights they have been in. They are also covered in scars, for the same reason, though they often fight with one another—physically and verbally. The fact that Drago has raised as many as he has is amazing.
