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.

Tyki is the head on the left, and Sherrill is the one on the right. Sherrill insists he's the older because he poked his head out of the egg first, to which Tyki replies it doesn't count because they share one body. Then, they start arguing with each other, which is an amusing sight to the other dragons, especially when they start trying to bite and claw each other, falling to the ground and rolling around flapping their wings. When they're not fighting, Tyki is the most carefree and laid-back, Sherrill being the smartest, always looking as if he's planning some evil scheme. Working together, they make a fearful sight... until they start fighting again.
