no outside exist. just inside. a dimension where inside is the only thing. so its like you in a Giant endless building. see a exit, it leads to another room, another building. sometimes large building exist. like a large warehouse or hanger, or just a huge room. sometimes rooms have monster. towns exist deep in the dimension. like the walmart Bandits. or the Costco Territories. there is the Warehouse Alliance who tries to take as many to use as factories for weapons. the Ikea union. the polices!
