The following account was recorded in the agent's log during your transmission: Tendrils of steam rise from the gleaming steel surfaces of what looks like a retro-fitted, abandoned Soviet-era nuclear submarine reactor room, somehow embedded in the wall of a massive, dry limestone cave. The air's thick with the smell of mineral-rich soil and ozone, and there's a constant, low-pitched humming noise. A perfect, undistorted mirror-like reflection of the surrounding cave somehow exists in the empty space where the reactor core would be, like a heat haze - it's reflecting the cave walls, even though there's nothing to reflect off of.
