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.

Gemini is surprisingly calm for a dragon with two heads, as she spends far more time resolving other's problems than fighting herself. She can hardly stand to see other dragons argue, and she rarely keeps to herself when fights break out. She shoves herself between the quarreling dragons, and each head will address one side and attempt to calm them. Rarely does she actually solve the argument, as the dragons become more angry at her than the one they were originally fighting with. Gemini has to hide herself away in her den as much as possible during mating season; her scars show that she has learned her lesson about trying to part two testosterone-filled males locked in battle.
