A good post I thought, in answer to your question about guards,
I do believe the difference between buildings and outdoors
is that the city guards patrol the streets and those places
deemed to be public whereas the would be thief/stealth assassin
can avoid detection by flitting from the shadows of one
building to another. When introduced many years ago this was
intended to test the stealth of those with the courage to
venture beyond the city walls of their enemies, however, with
the introduction of divine protection and so many safe areas
I guess this whole area does now look a little odd. That's
evolution for you, I suppose.
