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.

Pyrrhes is the mate of Toregene of the Dragon Horde Clan. He is a calm but playful dragon. Once he is interested in something, he learns everything he can about the subject he's interested in.

He gets along with everyone in his mate's clan but also misses his parents, who he visits from time to time. Chosen by his father in law, he currently leads its hunting party.

He also tightly bonded with his mate Toregene. They are always together and always there for each other.

He is very close to his daughter Assenat but frowns upon the goals of his son Cesarion. He doesn't approve the latter's "quest" for power, though he understands his son's reasoning. Because of this, he keeps out of the issue.
