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.

When Broca was an adolescent, her two heads got into an argument in mid-flight, resulting in a crash landing. Upon impact, both heads received nasty bumps. Because of this accident, Broca's twin heads are both convinced they are actually two separate dragons who had been fused together by an evil spell. For a few years, Broca tried to ask other dragons to help her find a way to reverse the spell, but when the other dragons heard what she was after, they openly mocked and insulted her. This pattern changed when Broca met the dragons in Sol Orb's dragon clan, who were the first dragons who actually took pity on her. They allowed Broca to join the clan, promising her that they would help her find a way to break the spell. In actuality, they are not only doing what they can to keep her from doing something rash to become two separate dragons again, but are also searching for a way to repair the damage that had been done to Broca's minds and help her remember the truth about her identity.
