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.

Yamoh is a notoriously seedy dragon. Lurking around Altea's skid row pub, he plays rowdy games with other dragons into the early hours, until he's either too exhausted or too inebriated to continue. As a vagrant, he has a habit of betting—the very habit that led to his loss of a home—and continues to make a shoestring living through gambling.

While most of the dragons he mingles with welcome him, Yamoh has a reputation for being a rude, foul-mouthed knave prone to outbursts of violence. It's probably this very behaviour that leads to his acceptance: unpredictability riles the scoundrels up, to the point of egging on fights between Yamoh and others—with the winner being paid just enough to maybe scrape him through the next day.

The proper dragons of Altea look down on Yamoh and his 'friends' with disdain, for all they see are unhealthy dragons with bad teeth, dreadful manners, all manner of offences committed and a sad, sad 'life' to lead.
