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.

True to her namesake, Wicked's gleaming red eyes, sister-head on her side, and malevolent appearance give her the devilish appearance of one that is truly unruly. But, it is common misconception, as Split dragons reside in a common pool of mystery. Wicked, crowned such simply for the want of a popular name, is often frowned upon by the other Splits on the scroll, and never approached by those bearing only one head for fear they may lose it. However, Wicked is kindly, and often seeks solace in her second head, who generally has little more to add than, "Wipe your mouth, deary, you've got crumbs on your chin."
