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.

Do's and Don't's is a junior floor assistant at the East Repository of Else and a student of the Magical Arts. Splits are not normally interested in this profession or a place with this many dragons together; Do's and Don't's really wanted to study magic and twice fought tooth and claw to convince the others that he belonged here. Once he stopped using teeth and claws and started using words and books, convincing others became much easier—whoops. He's not that fast a learner, and his heads arguing with each other about how to carry out a spell is usually what causes the slowdown. However, both are tenacious and practice often, with neither wanting to fall behind the other in knowledge. His name contains three apostrophes, and he's particular about everyone getting the spelling and apostrophe placement right. When he writes it out in the possessive form, such as when labeling the day's meal "Do's and Don't's's lunch", it makes some dragons shudder or gnash their teeth.
