Luminox Wyverns are a spritely breed, though their sharp beaks and talons may suggest otherwise. As the fall months approach, they begin to collect and store heat from fire mana, and as the temperatures drop off, they release it through localized spots on their bodies. This enchanted heat creates a bubble of warmth around the dragon, not dissimilar to sitting by a fire, and it causes parts of their hides to glow a striking orange. They are very popular with children, who are enraptured by their bright wingtips, glowing markings, and magical warmth. As a result, they frequently join in on human festivities, much to the humans’ delight.

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.

Bookkeeping is an accountant in the Specific Accountability House. Her parents truly named her Bookkeeping hoping she'd become a librarian. Her supervisor's supervisor's supervisor is a ke'maro xenowyrm. He's well-qualified for the job, but she can barely hide her fear of him. Coworkers, possibly without realizing, noticeably stand closer to Bookkeeping, Theistic the gaia xenowyrm, and Scaup the floret wyvern whenever their ke'maro boss is present. Bookkeeping is cheerful but easy to annoy, and she gets extra annoyed when anyone doubts her numbers, especially when she's been wrong only twice. She has a habit of grinding her teeth loudly when deep in thought.
