Because of their dual personalities, Duotone Dragons are extremely nervous and indecisive. When confronted, it is often the case that one head wants to fight while the other wants to run, resulting in the dragon trying to go in two directions at once. They are omnivorous, choosing to eat both vegetation and meat—although perhaps this is just another outcome of their indecisiveness.

Both heads can control the body, with each head having only marginal control on the opposing side of the body; this works when both halves want the same thing, but does not work as well when there is a disagreement. Despite this, Duotone Dragons can fly quite well, but can crash through the trees if one head becomes distracted.

Duotone Dragons can fight, using their large claws and heavy face plates to rend and bash their opponents.

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.

Dare-Oce (known as Dare and Oce) is a rather curious dragon. The red half, Dare, is always seeking out a nice cool place to rest in, while Oce, the other side, is always in pursuit of warm and sunny areas to romp around in. Many are confused by this, as their colors would suggest the opposite, but their simple retort is that only simple minds would think of such a thing. Due to their indecision, the Duotone is constantly fighting with itself, pulling in opposite directions towards their desired destination. However, this typically never gets them anywhere. The dragons who have witnessed this joke that if they tug hard enough they'll split and finally have a body of their own, however the two halves shudder at the thought of splitting from each other.
