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.

Ever since Delagon arrived at the cave he has been seen as quite unusual, while his friends care for and love both of him.  Although in his earlier days he was made fun of he didn't become sad and secluded, rather he chose to embrace his oddness.  Delagon competed in games with other dragons and when he was made fun of for having two heads, one of the heads said "Bet you can' can't breath fire and eat a meal at the same time."  The other dragon almost began laughing and said "You two may be odd, but you both have a good sense of humor."  Despite the odd beginning both dragons became friends and defended each other whenever the other was in trouble.
