I like that idea Saric. Actually, I'm thinking of some more elaborate to drive the idea that the place is extremely dangerous like only those who reached certain level (I'm thinking of at least master level) can gain entry to the fortress while to get to the shadowed land itself, they have to sign a paper of sort to say that they are going to enter the place of their own volition and that they are aware that if anything bad or traumatic happen to them in the shadowed land, the fortress goverment isn't liable to the damage (loss of items, innocence or even virginity XDD) pretty much along the line that venture to red zone isn't covered by insurance and equal to virtual suicide.
