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.

Who will be able to conquer a two-headed dragon when everything from his brute strength to his witty humor is doubled. That was what the over-confident dragon thought with both of his heads when he changed his birth name 'Agathon', which means 'good', to 'Anicetus', which means 'unconquerable'.

Anicetus' strength lies in the solidarity of his heads. They think, act, and feel like one as if they were never two separate heads. Not in everything though. The left head loves the sweet taste of vegetable while the right one likes to eat fresh meat. For Anicetus that alone is a serious problem, since usually he goes back to his cave hungrily, tiring out after dealing with the two heads' fighting over food.

With two consciousnesses in one body, Anicetus doesn't need anyone else. On each of his foreheads there's half of a heart shape. Anicetus had created them with magic as a sign that his two heads love each other with an intensity not weaker than any normal dragon pair.
