Neþr is an infinite fiery wasteland where the dead are doomed to wander for eternity, fighting off demons and trying to survive, there are various regions in Neþr, such as volcanic basalt areas, blue and red forests, sandy areas where ancient bones exist, and vast lava oceans and lakes, with lavafalls being common, and wastelands with nothing unique to them. There is an impenetrable roof over Neþr, keeping everything in, and an impenetrable floor deep beneath the blood red rock.
The demons will try to torture you, you have to fight them off to avoid torture, if they catch you and torture you, you will have a very bad time, they will torture you for years before releasing you to continue the chase.
You can use the resources found to try building a life, but certain demons can fly and shoot explosive fireballs to destroy your shelter to continue the fight.
