The following account was recorded in the agent's log during your transmission: Like, sunlight's filtering down through a massive, transparent geodesic dome that's somehow encapsulating the entire upper half of a kilometer-deep, abandoned quarry... the air's thick with the smell of damp stone and the sound of dripping water echoes off the walls. A series of cryptic symbols, etched into the stone in what looks like a mix of Sumerian cuneiform and ancient Phoenician script, are somehow causing localized distortions in the air's refractive index, bending the light around them in impossible ways. Water's slowly trickling upwards, flowing from the quarry's base back up to its rim, where it's being somehow reabsorbed into the rock.
