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.

The Freani-eplith, or Friends of the Forest, are a guild that has sworn to protect the forest and all who pass through it. There are four "divisions" within the guild: The Guardians, The Cloud Guard, The Earth Guard, and The Bloodseekers.

The Guardians do as their name suggests: they guard the land and the humans that pass through it. Members of the Guardians are often strong and proud of their power.

Costhel's two heads are a much needed addition to the Guardians' ranks. They've perfected the art of intimidation, often avoiding bloodshed just by showing up and roaring in unison. Their faces and necks are covered in scars, making them look quite a lot tougher than they really are. Nobody has to know that those scars come from frequent arguments between the two. Truthfully, they would rather spend their day asleep in the shade and not be bothered at all. However, the guild provides them with free meals and a spacious den, so they do their job without complaint.
