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.

Tidal Wave and Aqua Fang are the best of friends and the twenty-third dragon to be accepted into the cave. They get along well but even they get into quarrels. Both love to show appreciation to other dragons by catching them food. When the brothers were still a hatchling, Lightning that Lights the Sky, better known as Lightning, attacked them with a jolt of electricity giving them the fear of electricity. They sometimes have a difficult time making choices. When Tidal Wave wants to go left, Aqua Fang wants to go right. When Aqua Fang wants to go hunting, Tidal Wave wants to go take a nap. They still love each other even if they fight over things. Tidal Wave and Aqua Fang are inseparable, literally.
