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.

Umber may have scales of brilliant white,

But the magic that he casts is dark.

Esp has photomancy—spells of light

And scales that are a gleaming purple-black.

.

Both have little tolerance for "black"

When it refers to evil, and for "white"

When it means "good". They hope to shine a light

For those who ignorantly blame the dark.

.

Umber talks of goodness in the dark

Like sweetlings who have scales of midnight black

While Esp explains the evil found in light:

Like Thyras, the malicious, greedy white.

.

After all, dead bones are brilliant white

And death is the epitome of dark;

While 'windows of the soul', the gates of light,

Eyes have pupils. Slit or round, they're black.

.

Esp explains the world's not black and white

While Umber shows that darkness works like light.
