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.

Double-edge is a very violent dragon, often trying to pick fights with the others, particularly Tragic Night.  His two heads bicker with each other over every little thing, irking almost every other dragon in Flora and Ashes' clan.  The only dragon he tries to stay somewhat rational around would be his mate Glacia, though the reason for this is most likely because she's scolded him more than enough for it.  One of his favorite things to do in the cave, other than picking on Tragic Night, is training his daughter, Double-edged Glacier, to fight and hunt, even though she'll never become an adult.
