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.

According to most sane (and some insane) dragons, Rabid Twoface is one of the most extreme cases of split personality disorder that the land has ever seen. Sometimes, he stands at the front of the cave for hours at a time, blocking the cave while his two heads argue over which way to go. This also impacts Rabid Twoface's abilities; he tends to fight with himself during a battle against intruders, or make so much noise quarrelling that he scares off all the prey.

Because of his split personality, however, he's very good at seeing things from different points of view, and this often benefits Rabid Sea Breeze, the leader of the Rabid Ones, if he ever needs advice on making a decision. When he can't make up his mind, Sea Breeze presents the issue to Twoface, who promptly begins to argue over it. This helps Sea Breeze make decisions, which is the only reason he even keeps Twoface around other than pity; the way Rabid Twoface behaves, he'll find it hard to live on his own.
