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.

Karu (left head) and Nene (right head) are firmly convinced that they are the most ferocious beasts around, and when they aren't running around and stealing food from hatchlings, they spend their time getting into fights to prove their horribleness. However, due to the fact that they prefer eating in obscenely large amounts over working out, these brawls tend to end poorly for them. While they are definitely not as formidable as they make themselves out to be, they are quite irritable and irrational. It's not uncommon to see the two sparring in a wily clawing match over a slight error in dividing meat. Once, Karu had both of her eyes gouged out after accidentally nipping Nene's snout, rendering her utterly dependent on her not-so-wise sister.
