The following account was recorded in the agent's log during your transmission: Sunlight's pouring through a narrow slit in the rocky ceiling, casting a bright, jagged line across the surface of this giant, perfectly circular underground reservoir. Umm, the air's stale and musty, but it smells kinda like wet earth and damp concrete, and the pressure's pretty intense down here. Like, there's no sound at all, total silence, as Roomba vacuums somehow maintain a series of concentric, crop-circle-like patterns on the reservoir's calm surface, even as a miniature, 100-meter-wide replica of the Tabula Peutingeriana hovers just below the surface, totally unaffected by the water's presence.
