Ves tried to take back the tiny bit of spiritual energy he lost. It took some exertion, but he eventually managed to pull it away from the hungry rock.

Once he did so, Ves looked at the rock with a speculative expression. What was it? Why did it attract his spiritual energy? What uses did it have?

In any case, Ves already developed a theory of why this exotic initially attracted notice. It must have stored some spiritual energy upon discovery. When certain people came in touch with it, the rock must have discharged it into their bodies which caused them to faint.

He wondered what kind of energy the rock used to contain. Could it be a spiritual remnant of some long-dead alien or something? Whatever it contained, Ves found no traces of its existence.
