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.

Cerberus is the oldest dragon in his cave. He is very wise and gentle, but he can get very angry at times. Hatchlings are a weak spot for him, as he has no heir of his own. After centuries of unsuccessful attempts at pregnancy, one night Cerberus and his mate Christine discovered that she would be having an egg. The next morning, a "brave knight" came into the cave while Cerberus was gathering nesting materials. He killed her and took her head as a trophy. When Cerberus came back, he was destroyed. Outraged, he flew back to the knight's village and burned it to the ground. Now he guards the entrance to the cave every night to ensure his dragons are unharmed.
