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.

Kiouth and Algrith are the sons of Tarkai and Markai, and Aquaieth and Isolieth the Split dragons. Being the children of two (or four) of the most quarrelsome dragons in the family had its effect, and even before they had gendered, Kiouth and Algrith decided  took up the role of the family peacemaker. If even the tiniest quarrel was to break out anywhere in the large family caverns, the young Split hatchling would appear on the scene and stand resolutely in between the combatants. As not even the angriest dragon will harm a hatchling, the parties are forced to hear out the duo's lecture on the importance of peace, and are then made to sit down and talk out their issues. Strangely enough, this method also worked when Kiouth and Algrith grew up. As hatchlings, they were far too young to be given a clout on the head. Now, as towering adult dragons, they are far too determined- and big.
