It's a thunderous Tuesday night... You have been spending the time in the local casino, not to gamble but to not get wet. However, you got kicked out because you weren't gambling. Now, you are running around trying to find shelter when you stumble upon what appears to be a tunnel. It's open, so you enter to escape the rain. The tunnel extends very far, and you can't see the end. There's also a storage room nearby.

You feel an odd compulsion to go deeper.
