It was roughly six hours after he discovered the rock wall when he found the end of the wall. He had dealt with another two waves of Living Shadows since then. He looked into the part of the wall where it ended. After observation, he surmised that the wall was not in fact ended, there was simply a very huge opening on this side of the wall. The wall still continued some distance away, but he could not see it because it was covered by fog.
The opening itself seemed like a quarter sphere shape, as if one section of the wall had been scooped out.
He did not doubt that there was something in this opening, as he saw one large dark red dot. From the size and its color, Jack could determine this was not a monster that he wanted to deal with. Such indication on his radar meant that this monster was much stronger than him.
