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.

Strata and Terr (in ancient draconic, their names literally mean "sky and earth")represent the constant balance between opposites.  Unlike some two-headed dragons, the heads have separate names and completely different personalities.  Strata, the left head, is calm and peaceful, while Terr, the right head, is violent and aggressive.  

As the entity of balance, Strata and Terr are pro-mint, or more accurately, anti-winged.  Seeing the winged dragons as disrupting the coexistence of earth and sky, Strata and Terr fight against all those who are anti-mint.
