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.

Knock and Talk works in law enforcement. She usually patrols the network of caves she calls home, but she occasionally serves the town of humans a short flight away. Whenever there's suspected criminal activity inside a cave or building, Knock and Talk is usually one of the dragons sent to investigate, since having two heads allows her to observe more of her surroundings and process multiple theories at once. While most would just enter as they please, Knock and Talk always knocks on a nearby hard surface and requests entry first, engaging in conversation to try to convince the homeowner to let her in. Some officers think this is unnecessary, saying that asking permission hinders investigation, and they should not listen to criminals.
