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.

Sadie and Sapphira are like two very different dragons trapped in the same body. While Sadie, the right head, is very optimistic and open-minded, Sapphira is dark and pessimistic. Whenever Sadie thinks something is a good idea, you can be sure Sapphira will disagree, thinking it is stupid and will never work. Often, Sadie will have to drag Sapphira outside to get some air and to hunt. While Sapphira prefers meat, Sadie's favorite food is wild strawberries. The only thing they have ever agreed on is their mate, Dillon and Dallas. And even then, they disagree. While Sadie prefers Dillon, the funnier head, Sapphira prefers Dallas, who is almost her perfect match in negativity.
