As he made his way further down, he began sensing more and more presences.
At first, he pondered whether they were all coming from the guards -in which case there were many more than he had initially presumed- however he quickly realized that this wasn't the case.
The additional energy readings he was picking up were dim, and not in the sense that they were too far away -in fact, he could sense that they were just a short distance ahead. No, these signals were those of a weakened creature, it was as if they had been exhausted of all their energy.
~What's going on here?~ he thought to himself, as he heard the echoed moans of a multitude of creatures coming from the tunnel hallways that he was about to walk into.
He paused for a moment, trying to make sure that there was nobody of considerable power within the area, before continuing his advance.
