After a solid 10 minutes of wandering around the same rooms and corrodor, I gotta ask: How do I access the tunnel on the farthest room? That's where he says it is, but neither of the two right-most rooms seem to have any indication of a tunnel. I've uprooted everything uprootable in both of them, but I've not found a thing. Do I need a higher perception level? It's at 8 atm.
