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.

Cyonide's two heads generally agree with each other but unfortunately, although they have two heads and consequently two brains and characters, they have one big problem: only one stomach.

Cyonide's left head swears deer is the most delicious meat ever and the only thing a self-respecting dragon should eat, and Cyonide's right head refuses to eat anything but freshly caught fish, such as trout or salmon. As a large dragon like themselves needs to eat regularly, this leads to almost daily clashes between the two.

Nevertheless, there are quite a few things they agree upon. One of these is their love for a pretty two-headed female, Ayla and Halin O'Keeglan. It was love at first sight between the four, which lead to several children. Cyonide now has firmly established a territory which consists of two lochs and extensive woodlands, catering for both heads' taste, and which supplies enough food for themselves, the wives and all their offspring.
