Summary
The One Who Waits is about souls that live in a well on Mars. The story takes place far in the future, 10,000 years after there's no more life on Mars. A few guys from Earth land on Mars and go to the well to try the water. The creature that describes himself as "mist" comes out of the well and possesses one of them. The guy fought back for control and ended up dying. The creature then possessed another guy and shot himself. He then possessed the rest of them and trapped their souls in the well. The soul waits for more visitors to repeat this.
