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.

Yogurt is Yumzy is a confused dragon that probably belongs in a hospital. She repeats, day after day, "Yogurt is Yumzy, Yumzy, Yumzy", for that is all she knows how to say. It is not possible to eat yogurt in her presence, as she will shriek with fury until the yogurt is handed to her. People got tired of not knowing what to call her, so they started with the name Yogurt is Yumzy. The confused dragon was blissfully happy, and learned a few new words. Everyone agrees her name is perfect for her.
