This world is characterized by brown skies, a small, dim, red dwarf sun, extreme cold and giant glacial ice-plains, and seas so thick with salt that they are viscous and can be crossed by skiff or sled-like vessels.
Animals of this world, which is subjectively in the future, are hyper-evolved for the cold and the salt-seas. Major life-forms include Seal Beasts, Sea Stags, Giant Herons, and Oozers.
The Moon has crashed into the planet as well. It exists as a half-buried mountain in the southern hemisphere, still inhabited by the Silver Warriors who hollowed it out to build their cities.
