You were dropped into that "hole" by something.

You have no memory of before the fall. The hole is pitch black; you can see nothing.

The ground and walls are lukewarm and somehow moist. You cannot feel the boundaries of the space, making it seem endless.

Occasionally, you touch something slimy, and a slow, drum-like thumping—thump, thump—reverberates.

The walls are soft and offer no resistance when you try to break them. No matter how much you scream, no one comes to help.

Will I die like this?

──Just as you were about to give up. A voice spoke.
