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.

Three Shadows is Lurhstaap's first Split dragon. She is unusual even among Splits in that she has a total of three personalities. All respond to the name Three Shadows, and all are technically the same being, but manifest in very different ways. Her first aspect is bright and cheerful, yet aggressive. When in her first aspect, Three Shadows often assists in the physical defense of the Breedery. Her second aspect is more flighty, artistic, and whimsical. She prefers to carve sculptures with her claws and sing in this personality. Her third self is very self-contained, something of a 'resting' persona. The third personality keeps to herself and avoids contact with others.
