The following account was recorded in the agent's log during your transmission: The interior of a hollow, kilometer-long asteroid... Umm, rough, dark rock forms the uneven ceiling above, and the air's stale, with an undercurrent of acrid sulfur smell. A fine, grey dust coats everything, including the bizarrely twisted, rusted remains of what looks like ancient Sumerian irrigation equipment, strewn about haphazardly. The locust swarm's steady thrum has reappeared in the distance, accompanied by faint, ethereal echoes that seem to match the layout of the ancient Mesopotamian city Nippur - the echoes mirror Nippur's city plan.
