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.

Iblis and Thanatos are a very serious pair—often times finding little hilarity in anything. They generally speak only to one another in private locations, otherwise remaining quiet. They dislike having to deal with anyone else's problems and have little tolerance to listen to them—tending to move away so discreetly that others would continue the conversation even though there's no one there.<br/>Both are very drawn by battle and are known to be ruthless. However, neither Iblis nor Thanatos have the mind to kill a hatchling—some believe it's because they want a fair fight and others believe it's because they have some semblance of heart. There have also been rumors going around that they want a hatchling of their own to care for.
