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.

For a two headed dragon, Hecate Beeblebrox is remarkably single-minded. Her heads generally agree with each other about everything, and each nods happily when the other makes a statement. They chat to one another when no-one else is around to talk to—but the conversation is very dull, as there is no to and fro about it, just "yes", and "I agree". However, talking to her potential mate Gandaberunda is more complicated. Given his personality disorder, if they go head to head, she finds herself very torn and confused, as his two heads have opposing views about most things, and also, each can be extremely rude and insulting. But she perseveres—partly as he is her only chance of an egg, and partly because she does understand how very hard he finds it to talk to anyone at all.
