The following account was recorded in the agent's log during your transmission: A massive, stone Jomon burial cairn rises from the center of a frozen tundra, reflecting the pale, diffuse light of the aurora borealis above. Uh, the air's heavy with the scent of ozone and crushed stone, and it feels still, like the moment before a blizzard. Shattered slabs of frozen carbon dioxide - dry ice - cover the surrounding terrain, emitting a low, thrumming vibration that's causing the nearby snowflakes to reassemble into perfect, crystalline forms. Umm, the sun seems to be shining through the cairn, as if the solid stone is somehow transparent.
