"Is there a way of asking the computer to look up anything aside from locations of personel? Does it have simple cameras, or motion sensors in its system? We need to know a bit more about the locations of these things. So far, we have a SINGLE invisible ghast, which is frightening, a score of exploding crows, which is more frightening, and no idea where any of these things originated from. We need to find our next target. And this time, hopefully not kill it off the bat." This last bit sounds a bit irritated, and unsurpressed. With eyes scanning the hallways to either side, he hopes to notice at least a shimmer of an invisible creature. "Unless, Matsuko, there's a more specific idea we've neglected to attend to, but honestly, I'd be less inclined to think that all of them were killed by the equally butchered first team, save for a single one, and thus are no longer on this plane. We need to find a way to find our invisible army that, insofar as we've come, haven't bothered us. Is there a deeper underground to this facility?"
