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.

Within the Mountains of Elgar, Ianos lives as a member of the Posluga (dragons serving the High Family) and lives in a cave on the plateau of the mountain of Oulerun. As an egg he was discovered in one of the caves on the mountain and was raised by Ouranos, father-figure of the High Family. Once matured, Ianos was left to his own devices and found himself in the company of his fellow Posluga. He can be serious or playful, but his moods greatly depend on the emotions of those around him. His true character surfaces when in the presence of someone making an important choice, even if the choice has not yet been vocalized. In such cases, both of Ianos' heads will calmly begin listing off different options that can be carried out by the individual in dilemma. Though never in disagreement with himself, it has been commonly remarked that Ianos creates indecision in others, and often at the worst moments. In the Posluga, Ianos is the living representation of transitions and gateways.
