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.

Melancholy and depressed, Zip and Zilch can often be found laying on their stomach, their necks outstretched as they talk dolefully about how the world was a much better place in the past when more store was set by a dragon's character than by its appearance or lineage.  In truth, however, they were quite depressed and bothered even at that time, constantly complaining about how there weren't enough other dragons about. Back then, it was a common occurrence to find Zip lamenting the fact that he was eternally attached to Zilch, while Zilch loudly complained that Zip never washed his mouth out.  Now, of course, they have other things to complain about, things that a few of the dragons are occasionally willing to listen to, like the overpopulation of humans, dragons, and chickens, but eventually even those complaints run dry, forcing them to resort to their old arguments, often involving, "Zip, you have no concept of personal space," and, "At least I clean my claws after eating, Zilch."
