The following account was recorded in the agent's log during your transmission: Umm, massive concrete tetrahedrons are scattered everywhere, half-buried in the dusty ground like they were dropped from the sky. The air's pretty dry and still, smells kinda like hot dust, and the sun's directly overhead, making the shadows pretty much nonexistent. Water's somehow seeping out of the tetrahedrons, but instead of flowing downwards, it's forming perfect, hollow cylinders that just... stay there, suspended in mid-air. The hum of what sounds like a giant, distant engine is making the ground vibrate, and it feels like it's late afternoon.
