Rockfall (Caldos Quest 1-15)

Synopsis
The passage turned out to be a labyrinth and we got lost. In complete silence, I could hear Alice start to sob. I really wanted to comfort the girl, but suddenly we heard a rumbling roar in the distance.

Completion
Oh, please, no!' cried Alice. Having crawled half a mile, we saw that a cave in had blocked our path. We could see that our narrow passage ended there.
