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.

Kohryu likes to steal bird eggs and raise the fledglings to adulthood himself. As a result he is always surrounded by birds of various shapes and colours, each one thinking that he is their mother. When he isn't thinking of names and finding mates for them, he scours the land in order to find food for his feathered 'children'. <br/>Because there are so many types, he has a little trouble caring for all of them. Some of the birds will only eat seeds, others fruit and some merely feast on meat. The pride of his collection is an exceptionally rare penguin whose egg Kohryu found only by chance, but finding ample amounts of fish to sustain it is hard for Kohryu, as he dislikes water. <br/>Sometimes, Kohryu is overwhelmed with the urge to ask the other dragons to 'click' his eggs and fledglings. He has no idea what one of these strange 'clicks' is and doesn't understand why they would help him raise his birds, but he fears that someone might 'click' too hard and kill an egg by accident.
