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.

Symmetry, as her name suggests, is very symmetrical in both build and movement. Other than most two-headed animals, her two heads never fight and don't appear to belong to two different individuals; to Symmetry, having two heads is as normal as having two hands is normal to humans. It is simply convenient to have two mouths, or to be able to look in two directions at once (this is particularly useful when she is on duty as one of the cave's guards). Some dragons whisper that the reason why Symmetry's heads cooperate with such ease is that, due to a genetic defect, only one of the two heads contains a brain, but they would never say it aloud. One thing is sure, Symmetry has more than enough brains to shame anyone who offends her into silence with a witty remark—or if that fails to impress, there are always two sets of very sharp teeth you'd better avoid!
