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.

The reason Alura doesn't have two names is because only one of her heads has a consistent name. Her right head likes to be called Alura while her left one changes its name constantly. Alura often snaps at her twin head, while her twin head rarely starts arguments with Alura.

Alura and her twin were Origami's first friends, and often played pranks on him at first. When they began making more friends, such as Racer and Vine, Alura was the one who came up with their first names while her twin liked coming up with last names.

Sometime after the water dragon, Aqua, joined the group, a human quite suddenly showed up in the cave. Since then she's taken over the job of naming dragons, which leaves Alura and her twin rather sad because their main job is gone.
