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.

David and Samuel are two-headed dragons. They can best be described as complete jokers, spending their days teasing the other dragons and making everyone laugh. Many believe that the two heads are twins, but this is not true. In fact, David and Samuel are quite different, with Samuel preferring to study rocks and trees, and David always wanting to go on an adventure. This has lead to extremely awkward (and also hilarious) events in which David can be seen steadily marching off towards the unknown on the leg and arm he controls, while Samuel's arm holds the latest rock or bark he is examining, his other leg limp and being dragged along on the ground. In fact, all it takes is for David and Samuel to walk past the clan's camp to cause all of their clanmates to burst out laughing, forgetting what they were doing.
