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.

Mirielle and Kirika started out as the typical split dragon, fighting with each other constantly for control of the body. Then they realized exactly how physically powerful they were, and that two heads are better than one. Slowly they redirected their negative energy into a more practical form. After months of training, Mirielle and Kirika became a killer for hire, eager to be recruited by nearby fiefdoms. It may get them frowned upon by other dragons in Nadat's cave, but it also brings in plenty of trinkets and treasures for their trove. They're happy with the choice they've made.
