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.

Tamara Workman has nearly spent her whole life being envious of other dragons, as she somehow sees herself as being unrealistically "ordinary" and as a result seems to despise most other dragons in the cave, due to all the envy that has built up inside her since she was, well, a hatchling. She seems to think her name is the proof in the pudding, which she often says to her mate Tommy Workman is "horribly ordinary". She seems to think that maybe, just maybe, if she could somehow get her owner to change her name to something extraordinary, she may begin to become so, as if the name defines and has the power to change the dragon as a whole. If she just had the guts to approach the owner!
