Frostbite Dragons first appear at the beginning of winter, creeping in with the frosts. They have found their place in human lore as the spirits of snow, since they only reveal themselves during icy weather. In the depths of winter, they cover the world in blankets of snow and are believed to be responsible for the glittering frost that creeps over everything. Although they appear cold and distant, they are actually rather mischievous and enjoy spending time dancing through blizzards.

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.

When it comes to collecting shinies, Rufiyaa is only interested in "cold hard cash". It's gotta look like flat, roundish pieces. The stuff he collects must be solid and won't crack if he bites it, and it must be cold—the second part of his requirements isn't too difficult since he makes everything cold. His pile of treasure looks like a heap of metal money. If humans see it, assuming they're not shivering and worried about the weather, they'd jump out of their socks.
