I heard there were some that occasionally use the tunnels. Apparently I was lucky not to run into them.
The point is that I think there's always going to be a risk of someone coming across the containment area in a place like this. We won't know all the movements of the other clans, so to speak, and I imagine there are plenty of people from inside the mountain who go out and explore when the weather isn't so awful.
I'm not saying it isn't possible. I just think we should also plan for people actively trying to get in from the outside, too.
