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.

Mister spends most of his time in the icy peaks of his Clan's mountains, and he never comes down, even during winter. He has a habit of moving between many dens throughout the year and as such it can be very difficult to find him, but one can tell when they're near Mister's home when they see all the ice sculptures that he fills the landscape with. He is very interested in the craft of ice sculpting and will often give small sculptures as gifts to visitors.
