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.

Solar and Lunar are stargazing daydreamers, spending their nights staring up at the sky. They know every constellation and galaxy, and have scratched a map of the night sky into a cave wall, much to the amazement of their clan mates.

Solar and Lunar get their sleep one head at a time. The other head does all the thinking until it is its turn to sleep. This strikes all the other dragons as rather odd, and Solar and Lunar don't have many friends, since they are thought to be a tad bit insane. Solar and Lunar get along quite well with Tor and Fenris, though,  and so have taken them as their mate.
