He shook his head. "Large machine, yes, but it was doing something to space and time around it. The dwarven rescue team swore it was only two hours, tops, since they had gone in, not more than four hours that I had experienced. It may be better to not play with it, and just leave it alone. As for the other tunnels, they might not come out into the city at all, hence why I wanted to have teams check them out, since all of them appeared to head toward the surface. It might run under the city, or the machine might shift things around so most of the time there isn't anything able to tunnel into it. If the machine does what I think it does."
