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.

Fierce Fighter was taken as an egg very close to hatching. When three other hatchlings hatched with him, he had immediately started his fighting skills on the others. They all fought back, but Future Guardian always protected the others. When he matured, the first of the four to, he started to prowl through the caves, then flew through the sky at night. When all three others had matured, he stopped disappearing. 1.)Careful Dreamer took care of the disappearing, and 2.)He started to like Future Guardian. Maybe it was because she rarely fought and mostly guarded the others, or maybe it was something else. Who knows But, soon after both had matured, they decided to become mates. Usually Fierce Fighter is seen outside of the entrance, guarding, since Day Dream Maker doesn't bother to do anything.
