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.

ThingOne and ThingTwo's parents were big fans of the tall tales told to all growing hatchlings by the local dragon story teller. There was a particular legend about a large feline who wore a construction of twigs and leaves on its head that almost resembled the helmets that the human knights in the kingdoms across the mountains wore and went around causing mischief to the dragons. His parents continued to love this story far into adulthood and they named their first child after the feline's tiny, mischief-loving companions, two misfit pygmies. Unfortunately for ThingOne and ThingTwo, he hates that particular story because all the other dragons laugh at him when his namesakes are mentioned.
