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.
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.
