"house of chaos"

concept of game location: old house in the middle of abandoned lands, this place is hard to find, this place can find only those who wants to left this world, its place is crossroad between other worlds, this house is like broken puzzle build from pieces of different places, here doesn't work "properly" laws or real world and normal reality, randomly this place transforms and there is no two same combinations... well, there is a problem: who passed through these entrance, hardly returns same way...
