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 head on the left is names Rain while the head on the right is named Echo. But due to the fact it was a mouthful to say "Rain and Echo," everyone just combined their names into "RainEcho." While RainEcho shares the same body, their personality is totally different. Rain is the more mature and serious one. She is quite yet not shy. Echo is the bubbly one. She always seems to have unlimited energy. Her curiosity is surpasses MangoGlyder. Her voice is loud and she speaks before she thinks. Without Rain with her, she'd get into tons of trouble. Even though these two are like black and white, they love each other very much. The only arguing they get into is when Echo wants to play pranks while Rain tries to supress her.
