Blancblack dragons are a two-headed breed known for their hardiness and easygoing nature. They are omnivorous, with the cream head preferring to eat plants and the violet head preferring to eat meat, and can adjust readily to harsh climates. These dragons are sociable—both with other two-headed breeds and with single-headed dragons—and can often be found as adopted members of social dragon colonies. They are often considered symbols of balance and fairness, and likenesses of Blancblacks have been found in ancient ruins associated with law and justice. Females Blancblacks have longer tails than males, which they use as whips when defending a nest from predators.

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.

Difference is rather shy and reclusive when compared with his much more outgoing siblings. He doesn't care for the same attention and worship they attain, rather choosing to associate more intimately with others. Though he tends to keep to himself, Difference is also a great listener. He has a way of saying exactly what someone needs to hear at a given time, even when they themselves don't know it. He's extremely intelligent like his father and tends to stay close to him as well. Someday, Difference hopes to take on his father's position as primary judge of their home island, even though his mother, Crown, is currently doing most of the work. He seeks to help others and make the world a better place, even when he isn't sure exactly how to do that. He doesn't have Danarin's popularity or Jewelry's authority, so making close friends is more difficult for him. But what he lacks in outgoing personality, he makes up for in listening skills, intelligence, and empathy. He has much potential.
