The Tunnels

You can only grope for a way ahead as you crawl on your belly through the filth in the coal-black tunnels.

As you push forward, hoping for space, for light, and maybe even a way out, you realise the water is getting deeper. The air is staler.

But you cannot turn back. There is no space to turn in this twisted warren. And worse, it is behind you. Chasing. Growling. Slavering. Killing.
