Gusting Southern Nation Snows

As the name says, this place is covered by snow and has a fierce, freezing, southern wind. If you can stand the wind, this is a great place to go and have fun. The snow is so cold here it's perfect for making snow balls.
But you still have to watch out for monsters.
The monsters here range from level 10-15.
Every once in a while, a huge monster will appear that is level 40, but, very rarely, and it doesn't appear from a magic portal. The monster is undefeatable and no one knows why.
