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.

When the Great War broke out, Betwixt and Between, a serious, no-nonsense dragon, found themselves fighting just to stay alive and protect their mate, Twotails and Foureyes, and their hatchlings. When Flameflow, the treacherous Magma dragon, made an offer of sanctuary for the family of Split dragons, in exchange for their loyalty, Betwixt and Between was all too happy to accept, trying to ignore the bitter taste that betraying the old Weyr leader brought. Now, as one of the first who switched to Flameflow's side, Betwixt and Between find themselves ironically both esteemed and reviled: Flameflow and his supporters offer the Two-Headed a place of honor in the new Weyr of Flame, but those who converted only by force spurn them and call them the Two-Faced.

In the new Weyr of Flame, Betwixt and Between's job is to patrol the borders of the new lands, watching for invaders or encroachments. Their mate, Twotails and Foureyes, is responsible for raising their hatchlings.
