Black Dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

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.

Gravity 66 was named for her code. She was born from a White Stripe and a Black dragon, and has developed a peculiar fascination with stripes. Swirly ones, straight ones, thin or thick, she loves stripes. Her hoard of gold is small and arranged in stripe patterns, and if she sees a piece of cloth or something that she can carry away that has stripes on it, she'll almost certainly filch it. Although she isn't a Black Stripe, she seems to be trying to get as close to one as she can.
