The following account was recorded in the agent's log during your transmission: Umm, a big-ass waterfall cascades down into a pretty massive underground cavern... The sound of the rushing water's echoing off the stone, and it's pretty cool in here, the air's damp but it's not humid or anything. For some reason, the water's falling upwards at the edges, forming like a circular dome around the center, and some chunks of ice are stuck to the ceiling somehow, reflecting the faint sunlight that's filtering through some small cracks. Outside, I can see it's overcast, but I'm pretty far down here, so it's hard to tell what time of day it is.
