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.

Zilva and Xilva are so alike that their names are often interchangeable (and both sisters respond to pretty much any name that's thrown their way). Most consider them to be the same dragon, as they tend to do everything as one, from talking to hunting. They even argue as a team, which often ends in hilarity as both sisters simply parrot back what the other had said but with appropriate pronouns. However their close relationship means that neither can function without the other. If one decides to rest, the other is at a loss as to what to do next. They are a formidable opponent, but their lack of individuality is a major weakness. All their adversaries have to do is cause one to break from the team, and the other will completely fall apart.
