Tim shrugged, smiling still. He walked along the wall, rubbing it with his hand, feeling the contrast between the smoothness of the etchings and the roughness of the walls. He kept on like this for a bit, his intent to walk the circumference of the hollow. However, as he moved, he found his hand touching nothingness. But he hadn't circled around the entire area yet. He turned his light on the wall.

"Whoa... wow. Sophia." He stared at the wall intently, shaking his head. He took a step closer to it.

"What? What is it?" She asked running up to him. And soon, she found herself in the same state that tim was in.

In front of them was a perfectly rounded hole carved into the face of the center of the wall. Just like the runes, the hole was perfectly smooth to the touch. The entire passage was perfectly carved into the wall. Just as well, as Tims light shined down the tunnel--which appeared endless, by the way-- one could see tiny gems of some sort refracting the light all the way down into the hole.

Tim spoke curtly. "Holy shit."
