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.

Bratty and Catty, despite having conflicting desires and personalities, work relatively well together compared to other two-headed dragons. Each head considers the other her 'bestie,' and they'll frequently finish each other's sentences or say the same thing in perfect sync.

Together, they run a shop where they sell what seems like junk to most dragons. Even to them, it's junk. But, according to them, it's good garbage. And other dragons should totally buy all of it. The real problem with them selling the things they find in the garbage dump is that even though the items are totally wicked cheap, they're selling them for a totally wicked expensive price.

Altogether, they make pretty respectable shopkeepers, even if nobody buys their things. Their great love for cats (one of them wanting to pet cats, the other wanting to eat them) and excitable nature wards off a lot of customers, but they get enough business to stay in business. After all, best friends have to work together.
