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.

Kalianna is a sly and secretive dragon. Both her heads fight with each other, but will quickly gang up against anyone who tries to intervene. She is intensely smart, smart enough to be the equal of the other two-headed dragon, Swiftly comes the Darkness now (Skitden). Tveir Drekinn doesn't really count, because he seems to be two dragons trapped in one body.

Kalianna and Skitden frequently set up challenges for the other, like a riddle or a mysterious arrangement of stone on the ground that pointed the other in the direction of food, berries or something.
