The following account was recorded in the agent's log during your transmission: Snow's piling up on the frozen surface of a massive, crystalline cave. Uh, it's got this iridescent sheen to it, reflecting the pale morning light that's filtering through the entrance, and the air's crisp and still, with a hint of ice and rock dust. Water's trickling out of a series of tiny fissures in the crystal, and it's somehow... solidifying into tiny, intricate sculptures of what look like ancient cityscapes. The air's got this gentle, soothing hum, like a gentle engine vibration, but there's no sign of any machinery or source for the noise.
