The following account was recorded in the agent's log during your transmission: Liquid methane drips from icicles in the cathedral-like cave, their translucent surfaces reflecting sunlight filtering through the crystalline rock above. The air is biting and cold, smelling of frozen earth and dampness... somehow, no frost forms on my skin, even though I'm freezing. Umm, outside, I can hear this constant, almost-pitched whine that's building in volume – it feels like my ears are gonna pop from the air pressure dropping fast. Above the cave entrance, the pale sun casts an inverted shadow, as if light itself is somehow bending downwards into the earth.
