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.

Very few dragons even attempt to have a conversation with Zhang and Gan Jin. The two heads are so busy arguing with one another that they rarely notice when someone else is trying to get their attention. While they do manage to agree on what their favorite food is, and their preferred hunting methods and locations, there is little else they do see eye to eye on. Hilariously, most of what they disagree about are incorrect beliefs about the other. Zhang believes Gan Jin is lazy, often leaving bits of meat stuck between her teeth (this only happened once). Gan Jin is set in her conviction that Zhang is a liar, when in reality Zhang's only ever lied about seeing food stuck in Gan Jin's teeth.
