⛄ Snowberia
This extra cold land had formed during the Hot Age, probably to balance out the heat of the Great Desert... Another version is that the land was frozen by the Snowmaiden, the busty queen of this kingdom, who is also rumored to have built her Frozen Kremlin using some spacetime-freezing magic...
Either way, it's the land of Eternal Winter and many cold-loving creatures (e.g. snow angels, snowmen, etc) have made it their home.
This land is favored by shamans, also known as ice mages, who are immune to cold so much that they're running around almost naked while playing with snow and ice. The ones who lose in the snowball game have to strike a cool pose and get frozen into beautiful ice sculptures that become the winner's trophy for a day and the winner is free to do whatever they want with them (e.g. lick them like icecream).
This Snow Queendom has a surprising amount of magical creatures and animals who love cold snow as much as demons love their hot desert sands.
