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.

Assenat is the daughter of Pyrrhes and Toregene of the Dragon Horde Clan, great-granddaughter of Temudjin the great, sister of Cesarion. She disapproves of her brother's actions and intentions, but still loves him dearly. She is a committed dragoness, fighting for what she believes. She is a bit of an idealist and is at very good terms with her uncle Baatu, as well as her grandfather Ogedei and her cousin Tolui. She tries to contain her nephew, Hattusil. To secure Tolui's position, Assenat became his official mate, despite their platonic cousin relationship. However, they agreed to keep it an open and free relationship. She does love her son Kubilai though and spends as much time with him as she can.

She is generous and headstrong, bold and thoughtful. She is one of the best motivators in her clan and hunting party.
