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.

Stolen from his mother's cave as an egg, Bluegun behaves more as a carnivorous horse than a dragon. He eagerly waits to be ridden by his hatcher, following her around the cave system as she tends to her captured eggs, hatchlings, and weaker dragons. Sometimes he presents her with slain goats or boar as a token of friendship (bribery). His two heads are usually in agreement with one another but have different ideas on how to fly, resulting in his flights being perilous and more of a chore than helpful or fun for his hatcher. His name is actually split between his two heads, his left and more curious head named Blue, and his right, characteristically serious head named Gun.
