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.

Mas is the right head while Menos is the left. They usually know what each other is thinking but they don't always get along that well. They often have childish arguments but most of the time, it's nothing major. In fact, they secretly enjoy their banter with one another. When Mas and Menos have different ideas, like deciding whether to go left or right, they'll be going back and forth until one of them comes to an agreement or another dragon decides. Mas likes hatchlings and is patient with them and their antics, whereas Menos has no time for annoying, energetic hatchlings and rolls his eyes in disgust when he watches Mas playing with or taking care of them. Both of them are friendly and Mas tends to take things more seriously than Menos, who takes most things extremely lightly. Mas hates fruits and so does Menos but he secretly likes one type of fruit—raspberries!
