The following account was recorded in the agent's log during your transmission: Glittering crystalline stalactites hang from the ceiling of a cavernous, crystalline cave system, refracting turquoise light from an unseen source. The air's heavy with a sweet, metallic scent, like hot steel, and water trickles down the formations, forming a misty veil that shrouds the lower levels. Umm, I see... some crystallized structures are coalescing, looking suspiciously like Kabbalah-inspired merkabas, and they seem to be resonating with a soft hum. Shafts of rainbow-colored light dance across the walls as a low-pitched rumble vibrates the air, like thunder on a summer afternoon, and yet it's perfectly still and silent outside.
