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.

The prized heir of Silent Kill, Assassin Bat is the apple of his father's eye, a king to rival the warrior's power. He resembles S.Kill and is the first Alt-Born Dragon that he sired. He also takes after his father in his character—he is proud and powerful, loves to show off his skills as a fighter and is eager to prove his strength to him. Often, Assassin has challenged Kill to a duel, but his father beats him every time, even though he is a lot older than his son.
