View outside the walls lays nothing but a desert wasteland, Life inside Fortuna City is Harsh but outside is even harsher.
U may find a abandon ruin of a town, maybe raiders passing by looking for weakness.
Maybe the aftermath of a apocalyptic event that no one knows how it started, All this gave just one thought of point of view that seems to be unanimous...
And that's it's better to live inside the walls than outside...
