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, like most Splits, is usually solitary and tends to remain on his own. Despite this, he seems to retain a close relationship with his mate, Dune Viper, who he will visit on a monthly basis. The two are known for their love of puzzles and games, which can get pretty elaborate during their longer meet ups. They think up different riddles and puzzles to present each other and spend the visits solving them. Double is known for his cleverness, not just in front of Dune Viper, but also in general. He is a skilled and powerful hunter, often utilizing traps and unique strategies to lure certain prey out or separate them from their herd. He can get testy around other dragons, particularly if he finds them ignorant or boring (they're the same thing to him.) Dragons that earn his respect, however, also earn a life-long friend who is quick to come to their aid at a moment's notice. Double strongly believes in loyalty and will never quit on a true friend.
