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.

No one can dole out a tongue-lashing like Dea-Deis.  When the sisters are truly worked up, the recipient of their anger is likely to end up huddled in a corner under their own wings as they lambaste him or her over their intelligence, the honor of their mother, and the potency of their loins.  Once ruffled, the only way to smooth out relations is to wait; although their anger is bright and furious, it burns out quickly, and within a few days it will have cooled entirely.  However, the girls absolutely cannot stand Kira and Kat—Kira is unbearable, and Kat lacks a spine.
