"Hopefully it doesn't lead to a septic tank" you mutter to yourself as you peer down the drain. The darkness seems to peer back at you, and then it makes a far off gurgling noise.
Actually you are fairly certain that no one in this area uses septic tanks anymore, so at worst you might end up in a sewer... but you much prefer to imagine that you'll be able to navigate your way out to a drainage pipe in your basement, or maybe a gutter pipe in the yard. With a shrug you finally commit to your decision and push off... you dive into the dark opening and splash into the murky water of a drain trap. After some splashing about you work your way through the bend of the trap, and climb into another stretch of pipe. It's Pitch black in here, you can't see a damned thing. All you can do is press onward.
