The following account was recorded in the agent's log during your transmission: Uh, what looks like a bunch of discarded fetuses from some unknown species are scattered all over a dirty, abandoned, and severely rusted medical laboratory deep within some cave system. The air's heavy with the smell of decay and it's pretty damp, but for some reason, all the equipment's spotlessly clean despite everything else being caked in grime. There's a pretty intense high-pitched whine coming from deeper in the cave system... The lab seems to be surrounded by a halo of iridescent, glittering particles that appear to be slowly dissolving the rock itself, and outside, I can see a perfect, mathematically precise circle carved into the side of the mountain, pulsating with a faint, blue light.
