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.

After graduating from Seven Questions University with a degree in Unanswerable Questions, Chocolate Death Soulbones ultimately became a dramatist. His favourite classes were all maths taught by Rogue Rose, and like his mentor, he wants to find a mathematical proof for love. His dramas are a byproduct of this quest translated into a more accessible form. He always starts with a graph of the story with each character represented by a line. Some are parallels who never meet, some sine waves that keep going back and forth and intersecting with the rest of the cast, and—of course—there is at least one pair of asymptotes. Some people dislike his dramas for being too formulaic, but that's not his point. He is convinced there is an as-yet-undiscovered but elegantly simple equation to bring two lines together and staying together that—unlike the asymptotes—doesn't have an eternal gap, and hopefully composing his formulae will help him uncover it.
