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.

Zack is energetic to the extreme; he's always getting on the nerves of the other dragons, poking fun at them or generally making mischief. He is good friends with the Misfit Pygmies for this reason, and often gets bad ideas from them. The only one that can control him is his mate, Great Gospel; She'll grab him by the horn and drag him back to their nest, reprimanding him for making trouble.

Then the second she looks away, he'll be gone again.
