The Northern Lands Suggestion:

The Northern Lands are several places located to the North.The terrain found here is glacial.Polar Bears and other few NPCs dwell here.Unlike the dry, scorching environment;the Desert, the Northern Lands are the exact opposite of  that environment. This environment is frigid and players will take damage due to severe conditions by staying too long out in this environment. When a player takes adequate damage they will die.However, adequate armor might prevent conditions leading to a player's demise.
