The bishop’s masked troops can travel freely on all levels. I was almost cornered by them, and when I tried one escape route, they waited at a crucial spot in the stairs—which I had to cross to complete the next leg—and I was forced back. I prided myself in knowing the Cathedral top to bottom, but as I scrambled madly, I came upon a tunnel I had never noticed before. It led deep into a broad stone foundation wall. I was safe for the moment but afraid that they might find my caches of food and poison my casks of rainwater. Still, there was nothing I could do until they had gone, so I decided to spend the anxious hours exploring the tunnel.
