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.

Jasper and Frank is an "agent", or "agents", depending on how many dragons the heads are seen as. After they're through with someone, the victim tends to see multiple dragons anyway. They work for a mysterious higher power, a group of multiple entities who run the region that this two-headed dragon patrols. Jasper and Frank are tasked with hunting down anyone who deeply displeases the masters and either demand payment, drag them away, or beat them. Maybe any combination of those. They have several "business interests" which involve "collecting" from weaker dragons who share their space, and they will occasionally start fires when said "business interests" become unprofitable. Very clever, persuasive, dangerous, or shadowy folks know the various methods to evade Jasper and Frank or stay on their good side, perhaps even get little jobs from them.
