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.

Dark Boo knows something about herself—she is a female in the body of a male. Luckily for potential mates, she also happens to like females, so whether they know or not there are no problems.

She often hangs around a particular forest of the Enigma Mountains, popping out of the shadows to scare couples—dragon or otherwise—who visit the otherwise-peaceful spot. Often, before revealing herself, she listens in on their conversations, leading her to know the most gossip of any dragon around—as though she only jumps out at couples, she will listen to all said around her.

Her habit of eavesdropping makes her the only dragon to know of Crimson and Indigo's dilemmas, and though she wishes greatly she could tell them, she fears for their life with the overly attached Fira around.
