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.

Leon And Lola is—or perhaps are—the oldest members of the Vocaloid Clan, and among the least famous. Nobody is ever quite sure whether to talk about this dragon as one or two people; even though they share the same body, Leon and Lola insist that they are completely separate entities. Luckily they get on quite well, for their shared body means that they are doomed to have to put up with each other's presence forever. Although Lola is quite certain that she is female, their body is male, and to Lola's considerable disgust and annoyance Leon has taken the Bloodscale Dragon Karakuri Burst as his mate. Despite their lack of fame, Leon And Lola still enjoy singing together, and their voices are always in perfect harmony.
