Gold dragons are the ones most often killed by humans, who consider their scales to be extremely valuable. These golden scales grant them a high level of protection, similar to armor, and they use this to their advantage in battle.

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 progeny of Wild, Jacheongbi instantly won the collective attention from the clan members even as an egg. Everyone was very much interested in witnessing the evolution of a rare breed that had its innate traits preserved, untouched by domestication from humanity. The outcome turned out to be disastrous; the memory of mankind's atrocity vivid in her veins, Jacheongbi not only refused to inch out of her shell as she registered the presence of the Breeder to the point where it became physically dangerous for the hatchling to remain in the confines of her egg, but she stalwartly identified Breeder as a threat to her safety for the entirety of her hatchling years. Her prejudice was defeated only when she reached adulthood and logic finally kicked in. While reason commands Jacheongbi to correct her attitude, she finds it difficult to be on amiable terms with the Breeder after two steadfast years of rejection. She nowadays would shadow Breeder, but would fail at the last moment to apologize.
