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.

With scales black as ink and eyes that shine like the purest of emeralds, Call of the Dark considers himself the greatest black dragon in all of the Caves of Twilight. He fights with other dragons to prove his strength, but never uses his magic against another resident of the caves. Some say it is because as a hatchling, he used powerful magic during a friendly battle and seriously harmed his opponent. Though the other hatchling survived, he feared he may lose control of his warrior nature again.

Call of the Dark has an affinity for female dragons with brightly colored scales. No one is exactly certain why, but some suspect it is because he thinks too highly of his own scales. Seeing another dragon with dark scales not nearly as "perfect" as his own would be far too much for him to bear. Though he prefers dragons in shades of white, he has been known to stare off in the direction of yellow and pink shaded dragonesses as well.
