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.

Dorelzer and Gryythin are part of Sextem, a group of six dragons that were all raised together. They fought adamantly to be counted as two separate dragons in the group and eventually won, changing its name from Pento. The two of them have always been very separate from each other since the day they hatched. Dorelzer, the dragon on the right, has always been more demanding, aggressive and blatant than his brother Gryythin, who was born a much lighter shade than he is today and appeared almost female as a hatchling.

Both of them, however, enjoy flying. Once they grew their wings, there was no stopping them. Even today, they're rarely actually in the cave, usually circling the sky above it, accompanied by Tomasker or Auburnus and thoroughly enjoying themselves.
