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.

A true-blue two-headed dragon, Cyan and Jasper love to debate. They live by the motto 'there is always two sides to one story,' and somehow always manage to choose opposite sides. Their arguments never turn violent, but they can get pretty loud. Aero knows she can trust these two level-headed males. They have a great affinity for weighing options and finding a logical solution to almost any problem.

Cyan and Jasper love to eat cooked meat. Aero has seen them sprinkling seasoning on a recently killed cow, then 'cooking' it by breathing fire and charring the animal. She still doesn't know where they learned that.
