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.

Cetheno, although an adult, has always acted very boyish. His parents, two of the most alert and loyal dragons in the clan, are always trying to get him to be more outgoing. The truth is, Cetheno was meant to be a gift from the Mistress to another dragon keeper, but cetheno hatched too fast and refused to leave home. He is very quiet and shy, spending a lot of his time deep in the cave with Demitir, the first dragon in the Mistress' clan, where she passes on her wisdom to him.

Cetheno is rarely seen out of the cave, and is often overlooked when his hunting rotation is up. No one has ever seen him kill anything, but he insists that he gets enough food. The Mistress is one of Cetheno's favorite people to be around, and is sometimes found not far from where she is.
