The green world

 This is where you disappear into an unknown reality it is where every thing you see is just green when you walk into the the barkey looking tree there is no going back and every time you try to explore it you will keep coming back to the same tree you saw when you first got here so every time you walk past the portal tree you don't notice until you come back to the same tree. Every time you try to go through the barley looking tree you get through but something comes and pulls you back into the tree people don't last that long in there because they run out of water and food and some deadly gases so the world you us to know is know longer a thing. The world is only  unknown because every one who walks through it never returns from the deadly green world of horror
