The following account was recorded in the agent's log during your transmission: Crystalline shards of light are piercing the darkness, illuminating ancient Sumerian sigils etched into the stone walls of a vast, underground ziggurat. Umm, the air's thick and heavy, like, totally still, with a faint scent of frankincense, and it's like, late evening or something, with no visible sun, just an eerie, pulsing glow emanating from the symbols. Water's slowly rising, flooding the lower chambers, and I can hear this steady, low-pitched thrumming sound, like the heartbeat of some ancient, buried deity. The walls are somehow shifting, rearranging the sigils to align with the celestial bodies above.
