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.

Mydnachet is grouchy, withdrawn, and suspicious. Like several of the Breedery's other blacks, he was an abandoned egg, found by Lurhstaap on the outskirts of a cave system not far from the Breedery's borders. Although not hunting for black eggs at the time, the dragonkeeper picked up the egg anyway, and allowed his eldest pair of blacks, Sardonyxiar and Obseddiun, to raise it. Mydnachet is aware of his true origins however and unlike many of the other adopted dragons, he is bitter and resentful. Sometimes he feels betrayed by his birth family; other times, he hates the Breedery and thinks of it as a place to which he was kidnapped and enslaved (despite having no particular duties or tasks and being left to his own devices ninety percent of the time). Unsurprisingly he is not very popular, either with his own species or other Breedery dragons. Of course, he could just run away to the wilderness, but this seems to have not occurred to him yet. Or perhaps he's just afraid to.
