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.

A member of the Sylvain clan's search-and-rescue team, Yebira is the team's go-to supply runner during recovery missions. Having trained to fly while carrying medical equipment of different weights and fragilities, she is able to quickly transport items to the team when they search for injured dragons. Yebi also possesses knowledge of the clearest flight paths through the biomes, as she doesn't like the risk of obstacles snagging or damaging the carrying bags she uses. In her spare time, Yebi arranges backup caches of medicine around the clan caves, making sure that she will be ready to leave immediately should the need arise.
