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.

Jessie and James are two troublemakers in one body.  Jessie is more of a thinker and James is more dull-witted, but James puts force into their plots.  It isn't uncommon that the two heads argue with one another.  They constantly pull pranks on the other dragons, much to their annoyance.  Aramuto, the alpha male, often resorts to disciplining Jessie and James.  They are actually smaller than average and few dragons in the Trojevian pack tolerate their presence, as it often means trouble.  The most common recipients of their pranks are Ash Catch 'em and PeekAtYou.  Two of the few dragons that tolerate their presence are Venus and Athena.  That doesn't mean that Jessie and James won't hesitate to pull a prank on them.  To this day, Jessie and James are planning their biggest prank ever.
