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.

A dragon with a personality comprised of sassy sarcasm and clever foresight, Sin Master paints the very picture of a regular snarky Black with flirtatious habits. Most strangers take this at face value and don't think of her much besides when they wonder why she is ranked as one of the highest dragons in the group.

The dragons who live around her, however, have found that she is just using a mask when it is needed. Ones like the Albino, Sebastian, want nothing to do with her and cower away whenever she approaches, wary from the times when he's seen her in action. Others like the Silver, Hdq, speak to her politely and sometimes even ask favors of her, looking at her as a necessary evil.

Of course, no one actually knows any of this. Those who find out are usually taken to the local Magi's and thus forget anything that is too important to be known publicly.
