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.

Cub Cat is a pompous and evil dragon. He wants to be the clan leader after Nite Eye's planned downfall, but Clariona argues that it will be Aussie Nessie. He's mated to Dracthya Macabero, but she isn't very close to him. He admires her greatly, but Dracthya tends to view him more as a weapon than as a mate.
