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.

Radelle and Raegen can always be counted on for optimism and encouragement, and they have a knack for saying just the right words at the right time. Radelle and Raegen tend to have great health, probably in part due to their pleasant disposition. Though Radelle occasionally over-analyzes situations and worries a lot, Radelle only means to make herself and others as happy as possible. Raegen tends to be to goofy and insensitive even in serious situations, she can hardly become composed. She doesn't mean harm and isn't evil; she just lacks tact. Because of the marginal control both Radelle and Raegen have over their shared body they have learnt to corporate with each other. They can do this so well that Radelle and Raegen are able to predict what the other sister wants to do with their body and even wants to say. They have become so in tune with each other that dragons in their own clan don't even notice this, they move so fluid and smooth that they forget how hard it is to do that.
