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.

Coming from a long line of Two Faced Dragons, this dragon much prefers the simple name of its species. His actual name, he says, is much to hard to pronounce, when in reality, it is simply CatsandJerry, a combination of his parents' names. His adopted parent drops by to visit from time to time, and is the only human to get away with calling his real name. However, he has and will probably always devour any humans who figure out his real name. He cannot change it because of the look in his parent's faces when he bring up the name. "It is a proud heritage, to be named after your grandfather, father, and mother at the same time."
