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.

Zakuaris lives in the Dusk Divide Dragon Keep where he is known, along with his two sisters, as one of the self-christened Black Thunder Trio. His parents were a black and a thunder obviously, both born in the caves of the wild and not the Keep, which the Black Thunder Trio take pride in. The three siblings are rarely ever seen apart, and they eat, sleep, and fight together.

Zakuaris himself is the oldest of the Trio. His pride and unique alternative look has gained him some resentment with his other two "normal black" sisters, but they get along for the most part. Zakuaris is subject to his wiles and finds it hard to control himself. For this reason, he is known as the id of the Trio, always acting out of selfish reasons. He has found a permanent mate in the vine dragon Proserpira, whom he sympathizes with due to her also unique look among the other vines.
