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.

Isander is one of the fiercest of the black warrior dragons. He will put his life on the line to protect anything that is dear to him. His clan was at war with a neighboring Magi dragon clan, and the battles were always savage. Isander received a large, gruesome scar on his left wing from a battle with an elder Magi dragon. It was this dragon that had driven him into the Japanese forests in which his mate, Natsumine, and her clan was residing. He would have probably been killed if it hadn't been for Natsumine's intervention, though she couldn't bring herself to kill the elder. Ever since then, the two have deeply been in love, but her clan was strongly against it, and frequently attacked Isander. Isander did his best to hold his temper, for the sake of his love, but eventually, he could take it no longer and took Natsumine back to his home in the mountains of Romania. They have lived there ever since.
