As he slowly makes his way down the tunnel, it stays fairly level, but he notices a faint glow along the walls. It's not quite bright enough to let him see without the flashlight, but it's an indication that there's something up ahead.<br/><br/>If he continues to follow it, the tunnel spirals fairly widely, and, while he may not realize it, he actually ends up almost directly below where he was standing, when that lightning bolt struck, where the narrow passage will open into a small room, where an odd, blue-glowing stone rests amid a pile of rubble. It looks to be about eight inches in diameter, apparently made of glass, though covered with odd designs, and lit from within by an undiscernable light source.
