The following account was recorded in the agent's log during your transmission: Towering stalactites made of what looks like translucent, crystalline salt hang from the cavernous ceiling, refracting the pale blue light filtering through the ice-crusted entrance above. Umm, the air's heavy with the scent of damp earth and minerals, and it's so still that I can hear the soft creaking of the stalactites as they imperceptibly shift. Schools of bioluminescent, insect-like creatures – identical to those swarming the lighthouse – are crawling across the crystalline formations, their ethereal glow illuminating ancient, cuneiform script etched into the walls. Water appears to be flowing upwards through the crystalline structures.
