The following account was recorded in the agent's log during your transmission: Uh, sunlight's reflecting off the polished surface of a massive, rotating ice disk in the center of a vast, frozen cavern, creating a strobe-like effect that's making it hard to look directly at it. The air's dry and freezing, with a hint of a metallic smell, like someone poured gasoline on a pile of rusty scrap metal and lit it on fire. Water's somehow flowing upwards from the cavern floor, freezing into crystalline formations that are then getting shredded by the disk's slow rotation, and it's somehow creating this low-pitched humming noise that's vibrating through the air.
